Subject Re: TableViewRowEditor or actually ListAdapter throws InstantiationException
Date Fri, 13 Jul 2012 10:40:59 GMT
Hi Thomas,
sorry for the delay for the response ... and I'm still in holidays until
next week.

I never had a problem like yours, so please in the meantime could you post
a minimal sample ?
The best would be in a jira issue (and grant the flag for usage in asf
derived work).

But yes, from what I read it seems something we can fix, but we have to
make even some unit test to not introduce strange behaviours.

Thank you,
Sandro
