arne anka commented on JBIDE-2671:
----------------------------------
additional test seem to indicate that somehow the state of that visual part is stored -- the file above does not open at all, even when the ve is set to 100%.
whereas the mentioned jboss-seam-2.0.1.GA/examples/itext/view/pageSize.xhtml opens after setting ve to 100%.
but -- after trying to open above file (and receiving a gray editor) even the successfully opened pageSize.xhtml is gray until i switch to another unrelated editor. switching back to pageSize.xhtml it renders fine.
there seems to be an additional redrawing issue, maybe connected to that ve part as well.
i was to understand, that the ve part could be disabled utterly und complete -- or that at least it is initialized lazily. since i don't use it all it should thus not be initialized at all.
is it possible to split the editor plugin in one simple text editor which all features (completion, bean recognition, el) and no visual candy whatsoever -- and another visual thingumabob that does everything including flashing, yodeling and making coffee?
thus people w/o need for visual gimmicks whatsoever may install only the text editor and everybody else might use the fullfledged visual thing?

> 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!
