Support other picker widgets

[dmolineus]

If I use a 3rd party widget (f.e. https://github.com/netzmacht/contao-icon-wizard) within the custom elements extension which has a popup picker like the file or page tree widget, it's not working because the virtual field does not exists.

Affected conditions:

• CustomElements.php#L143-148
• CustomElements.php#L76-L93

CustomElements.php:76-93 gets never called from your extension because it doesn't execute onload_callbacks.

Maybe your extension has to do something like system/modules/core/controllers/BackendFile.php:70-72?

Next problem is that your extension tries to load the virtual field from the database IconWizardController.php:59 which fails Unknown column 'rsce_field_icon' in 'field list'

Another issue is that CustomElements.php:49-51 will not pass. This check is necessary to check for requests like contao/main.php?do=article&table=tl_content&id=1.

Thanks for the hints. Had tried it some times ago and noticed that even if I create the DC_Table and trigger the callbacks it would fail because of the mentioned conditions. I'll prepare my extension to support this requirements.

I prepared the widget to support the onload_callback and load_callback. Still the above mentioned limitations in contao-rocksolid-custom-elements prevents them to work.

If you want to test it, it's currently only part of the develop branch. https://github.com/netzmacht/contao-icon-wizard/tree/develop

It seems like your extension still tries to load the virtual field from the database. Please try the draft/improve-compatibility branch and tell me if it works for your extension.

It works fine now with the changes in the branch. Thanks for the great and fast support.

It’s in the master branch now.
