I think that with this new behavior it might now be impossible to use a component resolver to resolve components within an enclosure (that's my experience at least - they work fine inside enclosures for 1.4.2 but not in later versions):
I'm trying to work out how the changed behavior broke code that was working fine in 1.4.2 and have 2 possible theories: 1. As component resolvers are effectively only adding components 'on demand' then maybe the 'demand' is not forthcoming due to some change in the way enclosures are rendered in > 1.4.2. i.e. the container is not visible so no request to resolve other internal components is forthcoming and so 'on demand' results in those other components not being added. Or 2. Perhaps some intermediate but effectively transparent 'parent' container component is explicitly added in > 1.4.2 and the component resolver needs to add its components to that new transparent container instead of where it has traditionally added the components. Just theories at this stage... ;) > -----Original Message----- > From: Igor Vaynberg [mailto:igor.vaynb...@gmail.com] > Sent: Saturday, 6 February 2010 3:04 AM > To: users@wicket.apache.org > Subject: Re: wicket enclosure not finding child!? > > why dont you start a vote to have this changed back to pre-1.4.2 > behavior. if enough people agree we would have no problem applying the > change. > > -igor > > On Fri, Feb 5, 2010 at 1:13 AM, Girts Ziemelis <girts.zieme...@gmail.com> > wrote: > > According to the developers this was a "bug" in a the original > "enclosure" > > implementation, which allowed NOT to add all child components (if > enclosure > > is not shown on page).
