We are just trying to upgrade one of our biggest and most complex application to Java 21/Jakarta EE.
First, I wanted to ask when we will release the Jakarta EE version of Tapestry - any plans for this? Second, we found a real hard to pin bug in the changes to Tapestry 5.8.3 - we think it is connected to this commit: TAP5-2742: smarter page cache invalidation · apache/tapestry-5@48938d9 (github.com) <https://github.com/apache/tapestry-5/commit/48938d9a64239df37cbb7e2ad3c39ba196d1345e> When we launch the app with 5.8.3 we get the following error (with 5.8.2 everything works fine). We cannot reproduce the issue in a non-complex scenario. Any ideas? (could be similar to the issues mentioned by Chris Poulsen on the user's mailing list) Failure creating embedded component 'infoDialog' of myapp.components.pagelayouts.FullContentPageLayout:
