OnBeforeDelete in DataExtension - What's it for?

When I use DataExtension to add $has_many pdf files, I want to use OnBeforeDelete within the DataExtension subclass to remove those files before the deletion of the data object itself. But it seems not working.

To get around, I have to add codes into the data object's own class, which is not very ideal because the class doesn't have codes mentioning the pdf files.

Is this a limitation of the DataExtension of do i miss something?

onBeforeDelete() should work if your DataExtension extends the DataObject that is deleted. To have an idea what's wrong we'd need a to have a look at the code...

you are right it works ok.

Like other functions, i need to use $this->owner->Images() to remove images
