Max Rydahl Andersen commented on JBIDE-2671:
--------------------------------------------
That is called the WTP XML Editor - the completions should work from in there too...if not / that is a bug.
And Arne - this is an alpha, expect bugs we will fix them as soon as possible.

> the source tab stays gray, but after several attempts it opened somehow in the "visual/source" tab with some visual rendering (which i did not select! in perefernces "source" tab is set as default, visual part is set to 0%).
> "source" and "preview" are still gray and after checking these tabs "visual/source" is as well.

> to me it seems like the visual editor tries to render the page and fails horribly since parameters are missing.
> if this is true, it poses two questions:
> - why is the ve initialized at all
> - why is it not capable to cope with missing parameters -- it should be the case almost every time anything other than plain html is written.
> i got the same error for the iText testpage from the itext seam example
> jboss-seam-2.0.1.GA/examples/itext/view/pageSize.xhtml
> further attempts to comment out parts of the page resultet in nothing -- the editor tab that was open by default was in no way predictable, and switching to another tab made any tab plain gray.
> even a completely commented out page was not opened.
> below the code of the page, it is completely generated by seam!
