Nested columns in tableview only populates some columns [duplicate]

OK, new to java by several weeks, but have been programming for 30 years. The following code executes, but only the first column is showing anything. The data object is showing multiple rows of data, with fields of data that are filled in. I'm sure I'm missing something, and have looked through similar questions on here.

THANK YOU for the answer. Way to many years in case insensitive languages. This has been a quick and dirty exercise for me to learn java and the latest & greatest stuff or as I like to say New Exciting Technology (NExT!)
For anyone looking at the answer and still not completely clued in, here are the changes that made the code work properly.

This question is really a duplicate of: Javafx PropertyValueFactory not populating Tableview, but I'll specifically address your specific case, so it's clear.
Suggested solution (use a Lambda, not a PropertyValueFactory)
Instead of:
aColumn.setCellValueFactory(new PropertyValueFactory<Appointment,LocalDate>("date"));
Write:
aColumn.setCellValueFactory(cellData -> cellData.getValue().dateProperty());
For more information, see this answer:
Java: setCellValuefactory; Lambda vs. PropertyValueFactory; advantages/disadvantages
How do you use a JavaFX TableView with java records?
demonstrates replacing PropertyValueFactory with lambda expressions.
Solution using PropertyValueFactory
The lambda solution outlined above is preferred, but if you wish to use PropertyValueFactory, this alternate solution provides information on that.
Background
PropertyValueFactory uses reflection to determine the methods to get and set data values as well as to retrieve bindable properties from your model class. The pattern followed is:
PropertyValueType getName()
void setName(PropertyValueType value)
PropertyType nameProperty()
Where "name" is the string specified in the PropertyValueFactory constructor. The first letter of the property name in the getter and setter is capitalized (by java bean naming convention).
Why your application doesn't work
You have these three expressions:
new PropertyValueFactory<sresult, String>("DateEntered")
new PropertyValueFactory<sresult, String>("cDesc")
new PropertyValueFactory<sresult, String>("CreatedBy")
For your sample properties, the PropertyValueFactory will look for these methods:
"DateEntered" => getDateEntered()
"cDesc" => getCDesc()
"CreatedBy" => getCreatedBy()
And you have these three getters on your sresult class:
getDateEntered()
getcDesc()
getEnteredBy()
Only getDateEntered() is going to be picked up by the PropertyValueFactory because that is the only matching method defined in the sresult class.
Advice
You will have to adopt Java standards if you want the reflection in PropertyValueFactory to work (the alternative is to not use the PropertyValueFactory and instead write your own cell factories from scratch).
Adopting Java camel case naming conventions also makes it easier for Java developers to read your code.

Some times columns doesn't show data because of column names. eg,
new PropertyValueFactory<sresult, String>("cDesc")
and getter is getcDesc cDesc column may not display data. If you change code to
new PropertyValueFactory<sresult, String>("CDesc")
and getter is getCDesc CDesc column may display data.

For anyone else who still wasn't getting it after going through the above, my problem was that I wasn't specifying my setters with the "public final" designation.

PropertyValueFactory uses reflection to determine the methods to get and set data values as well as to retrieve bindable properties from your model class. The pattern followed is:
PropertyValueType getName()
void setName(PropertyValueType value)
PropertyType nameProperty()
Where "name" is the string specified in the PropertyValueFactory constructor. The first letter of the property name in the getter and setter is capitalized (by java bean naming convention).
Why your application doesn't work
You have these three expressions:
new PropertyValueFactory<sresult, String>("DateEntered")
new PropertyValueFactory<sresult, String>("cDesc")
new PropertyValueFactory<sresult, String>("CreatedBy")
For your sample properties, the PropertyValueFactory will look for these methods:
"DateEntered" => getDateEntered()
"cDesc" => getCDesc()
"CreatedBy" => getCreatedBy()
And you have these three getters on your sresult class:
getDateEntered()
getcDesc()
getEnteredBy()
Only getDateEntered() is going to be picked up by the PropertyValueFactory because that is the only matching method defined in the sresult class.
Advice
You will have to adopt Java standards if you want the reflection in PropertyValueFactory to work (the alternative is to not use the PropertyValueFactory and instead write your own cell factories from scratch).
Adopting Java camel case naming conventions also makes it easier for Java developers to read your code.

Some times columns doesn't show data because of column names. eg,
new PropertyValueFactory<sresult, String>("cDesc")
and getter is getcDesc cDesc column may not display data. If you change code to
new PropertyValueFactory<sresult, String>("CDesc")
and getter is getCDesc CDesc column may display data.

For anyone else who still wasn't getting it after going through the above, my problem was that I wasn't specifying my setters with the "public final" designation.

Why I only get one column when using TableView with JavaFX? [duplicate]

OK, new to java by several weeks, but have been programming for 30 years. The following code executes, but only the first column is showing anything. The data object is showing multiple rows of data, with fields of data that are filled in. I'm sure I'm missing something, and have looked through similar questions on here.

THANK YOU for the answer. Way to many years in case insensitive languages. This has been a quick and dirty exercise for me to learn java and the latest & greatest stuff or as I like to say New Exciting Technology (NExT!)
For anyone looking at the answer and still not completely clued in, here are the changes that made the code work properly.
colDateEntered.setCellValueFactory(new PropertyValueFactory<sresult, String>("Denteredon"));
colDescription.setCellValueFactory(new PropertyValueFactory<sresult, String>("CDesc"));
colEnteredBy.setCellValueFactory(new PropertyValueFactory<sresult, String>("Ccreatedby"));
public class sresult {
private String Denteredon;
private String Ccreatedby;
private String CDesc;
public sresult(String T, String d, String c) {
this.Ccreatedby = T;
this.Denteredon = d;
this.CDesc = c;
}
public String getCcreatedby() {
return Ccreatedby;
}
public void setCreatedby(String T) {
Ccreatedby = T;
}
public String getDenteredon() {
return Denteredon;
}
public void setDenteredon(String d) {
Denteredon = d;
}
public String getCDesc() {
return CDesc;
}
public void setCDesc(String c) {
CDesc = c;
}
}
}

This question is really a duplicate of: Javafx PropertyValueFactory not populating Tableview, but I'll specifically address your specific case, so it's clear.
Suggested solution (use a Lambda, not a PropertyValueFactory)
Instead of:
aColumn.setCellValueFactory(new PropertyValueFactory<Appointment,LocalDate>("date"));
Write:
aColumn.setCellValueFactory(cellData -> cellData.getValue().dateProperty());
For more information, see this answer:
Java: setCellValuefactory; Lambda vs. PropertyValueFactory; advantages/disadvantages
How do you use a JavaFX TableView with java records?
demonstrates replacing PropertyValueFactory with lambda expressions.

TreeTableColumn.visible : A bound value cannot be set

I make a simple JavaFX application. In this application there is a treetable with 2 columns and a check box. If check box is selected column 2 will be visible, otherwise not visible. To do this I bound tree table column visible property to checkbox selected property. When I click the check box column state change but at the same time gives.
Caused by: java.lang.RuntimeException: TreeTableColumn.visible : A
bound value cannot be set.
If I use bidirectional binding I don't get this error. But I don't need bidirectional binding. Is it a bug or I don't use bind correctly? Please use below code to reproduce this error. I use jdk1.8.0_111.

I think this actually is not a bug. It's definitely mysterious and unexpected behavior though. Part of the problem is that the binding conflict is coming from TableHeaderRow, which is created by the skin at display time.
The TableHeaderRow is responsible for rendering all the column headers, and it includes this built-in button for a menu that, by default, is a radio selection list of columns to show/hide:
As a result, the TableHeaderRow creates a bidirectional binding between these menu entries' selection state and each column's visible property.
It actually is possible to undo this binding but I found it annoying since the TableHeaderRow is null until the TableView is displayed. But, adapting this solution to access the TableHeaderRow, we can do something like:
TableHeaderRow headerRow = ((TableViewSkinBase) tableView.getSkin()).getTableHeaderRow();
try {
// get columnPopupMenu field
Field privateContextMenuField = TableHeaderRow.class.getDeclaredField("columnPopupMenu");
// make field public
privateContextMenuField.setAccessible(true);
// get context menu
ContextMenu contextMenu = (ContextMenu) privateContextMenuField.get(headerRow);
for (MenuItem menuItem : contextMenu.getItems()) {
// Assuming these will be CheckMenuItems in the default implementation
BooleanProperty selectedProperty = ((CheckMenuItem) menuItem).selectedProperty();
// In theory these menu items are in parallel with the columns, but I just brute forced it to test
for (TableColumn<?, ?> tableColumn : tableView.getColumns()) {
// Unlink the column's visibility with the menu item
tableColumn.visibleProperty().unbindBidirectional(selectedProperty);
}
}
} catch (Exception ex) {
ex.printStackTrace();
}
// Not strictly necessary but we don't want to be misleading :-p
tableView.setTableMenuButtonVisible(false);
But here's the kicker: you have to do this every time a column's visibility changes, because the TableHeaderRow has a listener that rebuilds the menu, and re-links the properties, every time a column is shown.
You could, of course, find a way to disable that listener.. but clearly this is already ridiculous and probably unnecessary.
Anyway, as you noted:
If I use bidirectional binding I don't get this error. But I don't need bidirectional binding.
I think the second statement isn't technically true: your use case doesn't require bidirectional binding, but it is actually appropriate here since there are other properties already linked with a column's visibility.
So, I would use bidirectional binding.
