Re: [Xsltforms-support] Cancelling loop/action

[Josselin M. <mor...@gm...>]

Hi Steven, 

Thank you very much for your answer. I don't know why I didn’t think of it before, as I use this method with another form… but not for a loop.  
It’s simple and efficient!

Just for my personal understanding, do you know (or anyone else) how works ev:defaultAction and if it’s fully implemented with XSLTforms?

Thanks a lot, 
Best, 
Josselin.
