How to display HTML content in CellList by UiRender

Dear All

I have a database table with a column of HTML contents which will come from a RichTextArea. Now, I want to display them with additional information in a CellList. As a sample,  although it is too much complex for the CellList and its AbstractCell, let's regard it as a Q&A web site like stackoverflow.com. A question and all its replys are writen in HTML format (end-users key in RichTextArea, and save it in database). I want to show the question and all its replys with HTML format by CellList.

I followed "Rendering HTML for Cells" (https://developers.google.com/web-toolkit/doc/latest/DevGuideUiBinder#Rendering_HTML_for_Cells).  But <ui:text> displays HTML strings as plain text in label, all HTML tags are directly displayed as characters. Means, I expect "Title" will be show to end-user, but end-user will see "<b>Title</b>".

I tried several way but no one works:

• Seems template variable "{var}" with <ui:with field='var' type="Var"/> only will be calculated in tags, and don't support javascript context. So if {var} or ="{var}" is out of any <tag>, end-user will see these characters directly, not the calculation result. Also, <input type="button" onclick="alert('{var}');"> will give you a black error screen directly.
• Seems triditional uiBinder way: <div ui:field="divA"/> and @UiField DivElement divA; doesn't work. You can't change it by divA.setInnerHTML(user.getBody()); in AbstractCell's render().
• I followed the "Getting rendered elements" to define interface MyUiRenderer extends UiRenderer<String> {SpanElement getNameSpan(Element parent);} but I can't get parent element if I just want to load it in the beginning instead of "click"ing it after every HTML tag and template variable is loaded and calculated.
• Finally, I defined <div id="{obj.getId}"/> in ui.xml and for (obj o:oList){DOM.getElementById(o.getId()).setInnerHTML(o.getBody());} . It doesn't work either. I regard it as a bug. I don't know how to report it.

So, Anyone can tell me How to display HTML content in CellList by UiRender if you know it. I think it should be very simple, I just didn't get the correct way. Thanks a lot !!!
