[rules-dev] Attach custom editor on guided decision table cell

[Michael Anstis]

I've been thinking.... a dangerous activity ;)

It might be possible to write a custom pop-up cell editor that embeds an
IFRAME and displays your JSP.

You'd need to scrape the final "formula" from the JSP and populate the
CellValue value property with the completed expression.

You might have issues with cross-site scripting, as I assume your JSP will
be on a different domain.

It'd be interesting to post any experience back to help refine what we have.

Thanks,

Mike
