Netbeans adding actions to output window

I have a netbeans platform application,
The Output window consists of two tabs in which am able to embed one of the tab in to a separate component with the following reference,
http://wiki.netbeans.org/DevFaqOWTabEmbedding
However, when i tried adding actions to it , the actions are not coming up in UI .
IOContainer ioc = IOContainer.create(new IOC());
InputOutput io = IOProvider.getDefault().getIO("test",
new Action[]{
new OneAction(),
new TwoAction(),
new ThreeAction()},ioc);
am expecting the three actions to be shown in the newly created window.
Something like this,
But am getting only the white window.
However, if i don't embed the tab in to another component, the actions appear.
Any help?

IOC has empty implementation of IOContainer.Provider method
setToolbarActions(JComponent comp, Action[] toolbarActions)
you should add JToolbar in IOC and implement that method.

Chart Wont Show When I Run It?

I'm trying to make a simple pie chart appear on a jpanel in netbeans with JFreeChart and got this:
public void createPieChart()
{
DefaultPieDataset myPie = new DefaultPieDataset();
myPie.setValue("Apples",new Integer(12));
myPie.setValue("Oranges",new Integer(23));
myPie.setValue("Mangos",new Integer(7));
myPie.setValue("Pears",new Integer(22));
JFreeChart myChart = ChartFactory.createPieChart3D("Damo's Fruit Sales", myPie,true,true,true);
PiePlot3D pie3D = (PiePlot3D)myChart.getPlot();
ChartPanel myPanel = new ChartPanel(myChart);
lowerMain_PNL.removeAll();
lowerMain_PNL.add(myPanel,BorderLayout.CENTER);
lowerMain_PNL.revalidate();
}
I get no compiler errors and when it runs the window appears with the button, but when I press the button my pie chart doesn't appear. Anyone know what I could be missing?

Check the layout manager of lowerMain_PNL. Netbeans form designer uses GroupLayout by default, so unless you changed it, that's what you got. Adding to a container using GroupLayout at run time is tricky, especially if the component contains more than one subcomponent (And requires adding components to the layout, instead of using the usual add() methods).
Change it to BorderLayout instead, since you are using BorderLayout constraints.

GWT loading elements dynamically on page load

I have some page that should have dynamic count of check boxes, and inputs depends on data received from database
now I do like this:
make rpc call on component load (getting data for inputs)
onSuccess add inputs dynamically on the form
result: form displayed without content(because it makes call async), only after resizing, it displays content properly
(probably I can fire resize event or redraw with my self, don't know how.. )
question: I am new in GWT, What is the best way to do this task? (Now i am using gwt-ext http://gwt-ext.com/, but I think it's no matter )
update: to refresh panel it's possible to call doLayout();

I'm not familiar with gwt-ext but in "vanilla" gwt you have two options:
Refresh your widget (that should show the result) in the onSuccess method
Proceed with the rest of your code not until the result returned.
To get a bit more precise i would need more of your code.

I had a similar challenge, the content of my widget was loading for a few seconds. I display a ""Loading, please wait ..."" label until the widget is loaded:
final VerticalPanel mainPanel = new VerticalPanel();
initWidget(mainPanel);
mainPanel.add(new Label("Loading, please wait ..."));
mainPanel.add(new myCustomWidget()); // this constructor uses RPC to get content
Timer t = new Timer()
{
public void run()
{
if (!mainPanel.getWidget(1).isVisible()) {
// do nothing
} else {
// remove label "Loading, please wait ..."
mainPanel.remove(0);
// stop timer
cancel();
}
}
};
// repeat every 30 miliseconds until myCustomWidget is visible
t.scheduleRepeating(30);

How to create controls dynamically in JFace Wizard

I have a jFace wizard, I am using this to create a new project type eclipse plugin. As you can see from image below, I have one treeviewer on left side, and a SWT group on right side. What I want is when ever user selects one of the item from treeviewer, I should be able to create dynamic controls on right side SWT Group. Say user selects Test One, one right side I should be able to create few controls like label, text and few radio buttons on right side, similarly if user selects Test Two I should be able to create dynamic controls on right side.
Currently I tried below code:
tree.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent e) {
for (int i = 0; i < selection.length; i++) {
String tempStr = selection[i].toString();
tempStr = tempStr.replaceAll("TreeItem \\{", "");
String finalStr = tempStr.replaceAll("\\}", "");
if (finalStr.equals("Test One")) {
Button btn = new Button(g2, SWT.NONE); //g2 is right side group
btn.setText("Blaaaa");
btn.setVisible(true);
container.redraw();
}
}
But when I run, I see no changes on right group. Can anyone guide me what I am doing wrong? Any pointers would be very appreciated, since I am new to Eclipse development and SWT.

You probably didn't set a layout on the g2 group. This is the common cause for controls not showing up. You can also try using g2.layout() to ensure that the new controls are correctly laid out after you create them.
Additionally you could look at using a StackLayout so that once you create a set of controls you can just hide them all at once instead of destroying when the selection changes. This is often useful so that if the user comes back to a previous selection, they will find the data they entered in the same state when they switched the selection. Here is an example.

Wicket panels need page refresh for javascript script to work

I am creating a web page with several tabs. To implement that I am using wicket AjaxTabbedPanel and several AbstractTab. In each tab I have tables with data and I am using a javascript script to make the tables sortable.
public TabbedPage() {
List<ITab> tabs = new ArrayList<ITab>();
tabs.add(new AbstractTab(new Model<String>("first tab")) {
public Panel getPanel(String panelId) {
return new TablePanel(panelId);
}
});
tabs.add(new AbstractTab(new Model<String>("second tab")) {
public Panel getPanel(String panelId) {
return new TablePanel(panelId);
}
});
add(new AjaxTabbedPanel("tabs", tabs));
}
When I load the page the table in the tab selected by default is sortable. However, as soon as I click any of the links to jump to other tabs (including the one of the tab already selected), none of the tables in any of the tabs allows me sort them (including the one that was previously working - the table in the default tab). If I refresh the page I can sort the table (of the tab selected in the moment of the refresh), but as soon as I click in any of links to switch tabs, the tables stop having the sortable capability again. Any ideas of why is this happening?
EDIT:
I just found that if I replace the AjaxTabbedPanel by TabbedPanel I don't have this problem. Although I'm still not sure why is that. Can anyone enlighten me?
add(new TabbedPanel("tabs", tabs));

Sorting the table by JavaScript is most likely a function called with a specific DOM-Id and seems to be executed 'onLoad'. it then accesses the currently displayed table and does it's work.
Changing the content of your Panel by Ajax doesn't trigger 'onLoad' so the function isn't executed again. TabbedPanel reloads the page and therefore executed your script.
Selecting a previous sortable table with AjaxTabbedPanel doesn't work because of the dynamically generated DOM-Ids.
Your solution is to add a AjaxCallDecorator to the links from AjaxTabbedPanel or to include the script or at least the function call to your tabbed panels.
At least this it what comes to mind without seeing any sources...
EDIT:
You might want to look at The Wicket Wiki. There's a description on how to call js after clicking an AjaxLink. That's exactly what should solve your problem.
Summary: Just add
link.add(new AttributeAppender("onclick", new Model("myTableSortingScript();"), ";"));
to the links generated by AjaxTabbedPanel.

In Wicket 6.0 you can run JavaScript on a component basis: Just override renderHead(IHeaderResponse response) for your component:
#Override
public void renderHead(IHeaderResponse response) {
super.renderHead(response);
response.render(new OnLoadHeaderItem("initalizeMe(\"" + getMarkupId() + "\");"));
}
initializeMe(mycomponentId) is executed every time the component is loaded by the AjaxTabbedPanel. This also works with the standard TabbedPanel.

No real idea since I'm not sure what the code is doing but I had a similar problem with my Panel Manager. Basically if you dynamically load HTML into a panel (a div or another element) using "innerhtml" script in the content will not be executed.
To get around this I scan the loaded content for "script" tags and append them using the DOM methods - this does run the script and makes it available. My "load" method is:
// Load Content
Panel.load = function(Content) {
// "null" the old (to clear it)
Panel.innerHTML = null;
// Load the content
Panel.innerHTML = Content;
// Load Scripts
var AllScripts = Panel.getElementsByTagName("script");
var AllScriptsCnt = AllScripts.length;
for (var Cnt = 0; Cnt < AllScriptsCnt; Cnt++){
var CurScript = document.createElement('script');
CurScript.type = "text/javascript";
CurScript.text = AllScripts[Cnt].text;
Panel.appendChild(CurScript);
};
};
Again, not sure if this is the issue, but it sounds pretty much on target from my experience.
