TYPO3 Core

Works for me on current master. As others also reported that it works, I’ll close this.

@Stefan ping me on Slack if you can reproduce it again, then we can sort it out. :-)

this is reproducable.

How I do it: I have in current master installed ext:news and ext:cal. Then a plugin is created on any page, and the select field with the available plugins contains News and Calendar. Selecting any value does not reload the form, so the dedicated flexforms are not shown.

Obviously it is only me. We tried this now with four people. Sorry to say this, there must be some weird configuration issue, and maybe the moon phase plays a role as well. Lets wait for other reports to come it, that help shine a light on this. I will close the issue until then.

After hours of tracing we found out that a garbled TCA is the culprit.
Caused by the bootstrap_package. Pull request https://github.com/benjaminkott/bootstrap_package/pull/210

so no core error, only a missing $GLOBALS in third party extension. Thanks for this catch.
