The Gantt chart allows you to add a projectTask by clicking Add New Task button, and the window that pops up allows you to select a predecessor, however the dropdown values are not loading.
I can see that line 102 of modules/Project/views/view.ganttchart.php has seems to have the select options commented out - as following:
Having looked a little more into the project tasks module, i wonder how/if people are using it successfully?
The demo suitecrm8 does populate the predecessor list, but the popup still looks buggy and you cant seem to assign a task when creating it in Gantt view.
I’m curious about this behavior in the demo. I am not sure, but I don’t think Suite8 uses the new UI framework for Project Tasks. So it would still be using the old code, the same you show above. So why does it populate?
I suggest you go hunt for some Javascript that is doing that populating work behind the scenes, after the page has loaded…
