When I use this property DatabaseEditor.class then comboBox is showing but when changing value from combo then following error is showing:-
java.lang.IllegalArgumentException: argument type mismatch
Please check my DatabaseEditor class & tell me why this error is occurred if you know about that.
Any ways, my main problem is solved
& its my duty to submit solution here for closing
Modification in PnlForQuery.java
Modification in PnlForQueryBeanInfo.java
and its successfully working.[/code]
Advantage of This Thread:-How to use combo box as a Property Editor? and conclusion is that we do not require to extend PropertyEditorSupport for selecting one value from multiple choice. Instead we set the multiple choice values to enumerationValues attribute of PropertyDescriptor's object.
