> The attached Quickstart reproduces the issue:
> # Click the link to Page 2
> # Press F5 to reload
> I believe the issue was introduced by the fix for WICKET-5904 (commit https://git-wip-us.apache.org/repos/asf?p=wicket.git;h=32a40bc ), which introduces a request-local ID generator for autocomponents. The IDs are stored along with the tags in the global MarkupCache, which can lead to collisions if the IDs are generated incrementally.
> The mentioned crash can be observed in Wicket 7.2.0 and 7.3.0-SNAPSHOT, whereas 7.1.0 behaves differently and renders invalid markup, replacing the 2nd occurence of the colliding ID by the markup of the first.
