Error in custom module

Hi

I am using the latest version of Sitefinity: version 5. I try to create a module with the module builder.
I first created a new module with a couple of fields. Everythingh worked fine. But after making changes to the fields (remove field and add a new one) and selecting the button ;Update widget templates and finish' I get an error on the page where I defined the new module.

The ContentViewDefinition with name 'ImagesFrontend' does not exist in configuration files.
You should either add the ContentViewDefiniton with such name to the configuration;
change ControlDefinitionName or load ControlDefinition programatically by setting
the ControlDefinition property.

t has to do with the type of field I added: media field. After removing the field reference from the created widget template, everything worked fine again.

What is the reason of this error?
Regards
Luc

Hello

For your info:
I created a small business edition with Sitefinity version 5.2500. I have seen that in this version there were some problems with image libraries.So I installed version 2523 now and will try to create the custom module with the media type field again. See if the problem has been solved...
