I ran into this and now that I know what's happening it doesn't bother me. I think if anything the messaging is not as helpful as it could be.
1) It was identifying the wrong missing field, which I think is fixed but won't come until 1.4.5 2) Perhaps the message should indicate that the wicket:enclosure doesn't support hidden fields within in (unless the wicket enclosure or the "child" is hidden") D/ On Dec 12, 2009, at 3:22 PM, Igor Vaynberg wrote: > hrm, already two people stumbled into this. i was of the mind that the > way it works
