[Wicket-user] Validation

[Nino Wael]

Hi   Might be me which has’nt been looking good enough into documentation.   So I have the following scenario and question:   Two listmultiplechoice box’ses where you can exchange contents of the list boxes by pressing one of two buttons see nice ascii grapichs below:   Listbox a                               Listbox B | ____________     ___          |----------------- | | | selected      |      | >|          |                     | | |                   |      ----          |                     | | |                   |      ___          |                     | | | notselected |      |< |          |                     | |-------------------     ----          |----------------- |     So if you select one of the list items in listbox a and click  btn “>” then the selected item should be moved to listbox B. Currently when setting up the page I set .setRequired(true) on both listbox’s this results in listbox B complains that it has’nt a selected value.   So question is how do I trigger only the relevant validation when pressing < or >.   Regards Nino
