Hi Maxim, I've deployed 7.4.1-SNAPSHOT with the fix.
About debugging the client side, you would : - watch the dev tool / network ajax requests and response - watch the ajax debug window if there is any js commands in the ajax response that has not effect (you can copy/paste them in the brower's dev console) - look at the rendered source, also for the js commands in the widget initialization - clone wicket-jquery-ui and put some 'console.log' in the relevant javascript statements. - if still no clue, start from scratch in a quickstart... :/ Hope this helps, Sebastien
