[opencms-dev] 10.5 Error dragging a dynamic function to a pag

[fhsubscriptions at componio.net]

Hi list,

I ran into a problem when dragging any dynamic function to a page which
leads to the following stack trace. The function gets not persisted and
is no longer visible once the page is reloaded.
The funny thing is that several functions are already on the page and
work as intended. The only thing changed is that we upgraded from 10.0
to 10.5.

Any ideas?

Thanks

\Fabian
