Bug #103212
openWorkspace page preview not working
0%
Description
When I want to open a page preview (/typo3/workspace/preview-control/?token=xxx&id=123) in a none-live workspace in a TYPO3 12.4.11 installation I just get the BE loaded again and not the split FE view. Everything is fine in the live workspace.
After some debugging I found out that the route is not matched in TYPO3\CMS\Backend\Routing\Router::matchResult() because the route path for workspace_previewcontrols is configured as "/workspace/preview-control/" and the trailing slash seems troublesome. At least it's the only BE route path that has a trailing slash. When I remove the trailing slash everything works again as expected.
I got these problems at least since TYPO3 12.4.7. I can't tell if this problem does exist in previous TYPO3 versions. At least in TYPO3 10.4 everything works as expected.
On a side note I uninstalled all 3rd party extensions but that didn't change everything. So it seems to happen even with a vanilla installation.
