Backend Preview dauert extrem lange

[Runner668]

Es passiert nur wenn eine Komponente mehre Repeatings hat.

z.B. folgende Komponente braucht Typo3 ca. 1 Minute Backend Preview zu generieren.

Hi @Runner668

Thank you for your report. The preview of content elements in the backend is gathered by using the FormEngine API. Maybe there are some hooks/processes taking a long time to finish the generation. Without any debugging/additional information I fear there is nothing I can do here.

Hi

I encountered this issue in a setup with a label_userFunc defined in the TCA of an inline relationship.
This hook called BackendUtility::getRecord in order to fetch more record fields, and it was slow.
I fixed the hook, and the preview is now pretty fast.
