Re: How to wrap an existing div into an HTML widget ?

It's working fine now.

My mistake was that somewhere on the page I was doing this action:

RootPanel root = RootPanel.get("content");
root.setStyleName("content_style");

so instead of doing this, I did:

Document.get().getElementById("content").removeClassName("content_style");

And now I am able to write

HTML myHtml = HTML.wrap(element); // element retrieved by GQuery.

So my problem is solved.

However, I cannot now add widgets to the element : <div id="content"></
div>
using root.add(new HTML());

Why is that? any workarounds ?
