(old) Extensionmanager Popupwindow cannot be closed after installing depending extensions
i get the following js error when i install several extensions that are depending on each other:
parent.TYPO3.EM.Tools is undefined
Steps to reproduce:
- use old extension manager
- uninstall extbase and fluid if installed before.
- install fluid. fluid requires extbase to be installed. install extbase. another popup windows opens. after installing extbase, the window shoule be closeable via "Close window." but that is not possible.
