I have edited the ListViewData.php file that is located in include/ListView/
When I move it to custom/include/ListView/ the changes I made no longer work.
How do I direct SuiteCRM to look for ListViewData.php in the custom folder without modifying files outside of the custom folder?
Is there a way to extend the ListViewData.php file somehow?
I didn’t look into the specifics for that file, but normally you should be looking at overriding a method in the class, using the extension framework (instead of just replacing the file).
Introduction The extension framework provides a means to modify various application data inside SuiteCRM. For example it provides a way to add or modify vardefs, scheduled tasks, language strings and more.
The mechanism is slightly more complicated...
Look for examples online.
