TYPO3 Core

When selecting a file, link, page or anything else from a popup wizard, the selected value e.g. "file:5" is not inserted in the input which is used for validation and submission. This leads to false validation errors on required fields and loss of information when submitting the form, because the selected and visible value is not transferred.
The value is, however, transferred to the input after some random clicks outside the visible input.
