Option group has a value change listener just like any other vaadin field, and inside that you can check if value equals "Custom".

Here is an example of code. Warning : it works only if the method setImmediate(true) is used !

Texfield text = new Texfield("I am a textfield disabled by default");
text.setEnabled(false);

final OptionGroup optiongroup = new OptionGroup("");
		optiongroup.setMultiSelect(false); [color=#2db93f]//if true, vaadin creates checkboxes, if false, Vaadin creates radio buttons[/color]
		optiongroup.addItem("A");optiongroup.addItem("B");optiongroup.addItem("C");
		optiongroup.[color=#ed1a52]setImmediate(true);[/color] [color=#2db93f]// Do not forget this line ! without it the click event is not send to the listener[/color]

		optiongroup.addListener(new Property.ValueChangeListener() {
			public void valueChange(ValueChangeEvent event) {
				if (optiongroup.getValue()=="A") text.setEnabled(true); [color=#2db93f] //If A is selected, the textfield becomes enabled[/color]
				else text.setEnabled(false);                       [color=#2db93f]//Otherwise, the texfield is still disabled[/color]
		}});

I am using Vaadin 7.1.5 and its saying optiongroup.addListener is deprecated, can you please confirm ?

Marius Reinwald

For a ValueChangeListener use: optiongroup.addValueChangeListener. The addListener method of the base Component class was deprecated as of Vaadin 7 in favor of more specific methods like addClickListener, addItemClickListener, addValueChangeListener, addTextChangeListener, ....etc.

Henri Sara

As the deprecation message says, it is replaced with addValueChangeListener(...).

Philippe Baumard

For vaadin 7.1.5 we have to change the code see https://vaadin.com/forum#!/thread/3603213
