Bug? WYSIWYG designer stays blank and closes

[techknight]

Everything was working fine. Was working on my design in designer then suddenly the preview window closed.

I reopened everything and its staying blank. then closes.

Tried restarting B4J and no difference.

If I open another project, its fine.

I attached my layout to maybe see what borked it?

Somehow the text in Label6 and Label7 became Null. Not sure how it happened. You can change it and it should work.

I've made a change in the way such errors are reported to make it easier to fix.

I think I know.

I had a bunch of labels selected at one time to change the Tag line all at once, and then to change the text back to "" all at once. Thats when everything suddenly went bonkers.
