I am new to wicket. currently in my project we are using wicket. my view page is looks like a tree view. right hand side we have displayed tree view and left hand side we have to display the corresponding panel for the selected tree node. my problem is, currently, i have add a dropdown choice at the top of the page. if we select the value from the dropdown choice, then we need to display the textarea in some of the treenode's panels. if i am selecting another value from the dropdown choice, then again we need to add another text area for same panels. present i have added the AjaxFormComponentUpdatingBehaviour to my dropdown choice. but i am unable to create the text area in the panels. please help me to solve this issue.
