Hello Dachcom Team,
i'm using Pimcore 11 and formbuilder 5.0.3.
i want to add an Validation Message for Dynamic Multi-File Not Blank, but i can not find any field in backend to do this. See screenshot in attachments. In general the validation is not working. I have tried to debug the validate function in DynamicMultiFileNotBlankValidator Class and nothing happens. Could you please investigate it.

Thanks and best regards,
Eric Mititelu
