Re: MyFaces Tomahawk ignores checkbox in dataList on first submission

[Wally Hartshorn]

I tried that, but got this error: "Attribute preserveRowStates invalid for tag dataList according to TLD". Apparently preserveRowStates is defined for t:dataTable, but not t:dataList. Any other ideas? (Incidentally, we've upgraded to Tomahawk 1.3, just in case, but have the same problem.) >>> [EMAIL PROTECTED] 7/20/2006 1:08:16 PM >>> Try using preserveRowStates=true on your t:dataList and see if that fixes the problem.  There's some odd behavior of UIData component state saving that still needs to be addressed for JSF 1.1.
