Hi Harsha,
For radio buttons, the select (and not press) event is fired whenever a radio button is selected. For your scenario, however, you need to listen to the select event of the RadioButtonGroup.
Step 1 : Create all your RadioButtons within a RadioButtonGroup. (How?)
Step 2 : Listen to the select event of the RadioButtonGroup (and not RadioButton)
Step 3 : Use an event handler similar to this for the select event :
select : function() { var oSelected = oRadioButtonGroup.getSelectedItem(); if(oSelected.getKey() == "<key_of_limited_liability_radiobutton>") { oComboBox.setEnabled(true); } else { oComboBox.setEnabled(false); } }
