Last time I checked, and it's been a while, the setOutputMarkupPlaceholderTag behavior was to create an element like "<div id='wicketId' style='not visible' />" and then when you set it back to visible you end up with the proper html: "<div id='wicketId'>content here</div>". I don't know anything about the draggable behavior but I assume it must be client-side stuff attached to the DOM node. When you set the panel back to visible wicket will do an outer html replace and you end up with a new DOM node that doesn't have your draggable behavior attached.
BTW, this is a bit of speculation but sounds reasonable eh?

My question is that even though I add a draggable behavior to the new panel and do the proper replacement, it stops working as soon as I start of with an invisible panel (with setOutputMarkupPlaceholderTag(true)). I thought the whole objective of setOutputMarkupPlaceholderTag is to just to do an inline style change to invisible while holding the rest of the code including the component id's the same). public void setQuestionFormatPanel(QuestionEditorPanel qfp){ questioneditorpanel.replaceWith(qfp); this.questioneditorpanel=qfp; } On Mon, Nov 23, 2009 at 2:00 PM, Martin Makundi < martin.maku...@koodaripalvelut.com> wrote: > > This drabable code works fine until I set isVisible(false) on the panel I > > want to drag around.
