JavaFX 2.2 Remove Pagination's selected page label

I want to remove the Selected page label (see image below) of the Pagination control.
After digging into caspian.css I wasn't able to find any clue about how to do that. By code I also didn't find any method to remove (or eventually hide) this label.
Is there a way to do that in JavaFX without re-implementing the whole control ?

Use -fx-page-information-visible
It's described within these links:
http://docs.oracle.com/javafx/2/ui_controls/pagination.htm
https://docs.oracle.com/javase/8/javafx/user-interface-tutorial/pagination.htm#JFXUI459
https://docs.oracle.com/javase/8/javafx/api/javafx/scene/doc-files/cssref.html#pagination

I couldn't find a way either to hide just the label, but would it help to hide the whole button?
.number-button:selected{
-fx-opacity: 0;
}
That would hide the current selected button.
It's not what you actually wanted but maybe it can help you.

GWT- PopupPanel with search?

I am looking for a way to create a popup dialog box when a user double clicks a textinput field that will contain a scroll-able list (from database table) where the user can select a field, hit ok, and have it placed into the textbox when popup closes.
The other major requirement is to have a filter/ or search field in the popup to aid the user in finding the correct option to select from quicker.
What is the best way to implement this?
Modification to gwt's popup panel? maybe a JOptionPane? are there any simple solutions already designed for free commercial use?

You could implement this with a com.google.gwt.user.client.ui.PopupPanel. You can make a PopupPanel that contains a ListBox with your data from the database, along with a OK button. When a user selects a value and hits OK, you should utilize an EventBus along with a custom Event that will pass the value to the field on the page. The page will have an event handler that will catch the event and put it into the field.
Another option is to use a com.google.gwt.user.client.ui.SuggestBox. It is a box that autocompletes / suggests values as you type, kind of like the Youtube search bar.
I can offer more resources to help you accomplish this, if you'd like.

GWT- dynamically make widgets non-editable

As per my requirements, I need to make a widget textbox prepopulate based on a selection, then under specific scenerios make the prepopulated field non-editable (from editable) without the page reloading.
The prepopulation works fine, but when I try to change my widget textbox to non-editable from the code (a validator), nothing changes. Of course I can easily make a field editable or noneditable easily on page load by setting my widget attribute directly in sql developer. But I need this to happen on the 'fly'.
So what is the proper strategy?
My thought is the widget is activated on load, and if I change the widget property I need a way to tell it to look there again w/o reloading the entire page?
Any thoughts would be greatly appreciated :)

I think TextBox#setReadOnly should work.

Wicket, how to lazy-load DropDown choices on click?

I have a lot of DropDownChoice components with many items in a form, and on loading the form, I'd like to display only the saved selected options. When the user clicks on a DropDownChoice, I'd like to ajax-load the full item list on the fly.
Can this be done?

Add a OnChangeAjaxBehavior to your dropdown-component. Override the onUpdate-method and add another component to the target. The chosen value of the dropdown-component is inside its model.
Update: Okey, I think I know what you're trying to achieve. Add an AjaxFormComponentUpdatingBehavior to your dropdown component with "onclick" as constructor parameter.
Override the onUpdate-method and add your dropdown component to the target. Before you do that, update the dropdown model, so that it now contains all values.

If you have a lot of options to show then using <select> is not the best option.
Better check http://ivaynberg.github.com/select2/ or http://livedocs.dojotoolkit.org/dijit/form/FilteringSelect or any other JS based component which can load options on demand via Ajax.

Maybe you could go with the AjaxEditableLabels... Using the AjaxEditableChoiceLabel from Wicket Extensions, you'll get a compponent that displays the current value as a Label until clicked and the changes to a DropDownChoice via Ajax. That should be pretty much like the solution you're looking for.

GWT hyperlink problem

i am using GWT Hyperlink for Click handling.I used rpc for showing the records in a dialog box by clicking on that link.but it is moving to home page immediately and showing the dialog box there.Please suggest me the solution for this problem.

Hyperlink should be used in combination with History (http://code.google.com/intl/nl-NL/webtoolkit/doc/latest/DevGuideCodingBasicsHistory.html) changes and not for click handling alone. When using Hyperlink the History token is updated, which will probably trigger the History change which will direct to the homepage, Next the click is handled which shows the dialog
EDIT:
Just as David mentions it's better to use the Anchor widget. Because Anchor is a native html element A, it's usability is better over using a span or div.

I concur with Hilbrand, but recommend anchor tags in such cases.
<g:Anchor name="whatever">Click me</g:anchor>

For this case I would suggest you to use CustomButton instead of HypherLink. For that custom button give some styles to look like a hypherlink. If you use label you cannot focus using keyboard.
Use hypherlink only if you are planning to give history support.
