Siebel TBUI View cannot render Gantt Chart Applets

I was trying to do a Proof of Concept for a project, and it was around Siebel's Task Based UI system. The scenario was for a Service Request manual assignment system, and the user was supposed to assign the SR to an available agent. If you drilldown on the "Status" field of an Activity from the "Service Request Detail View", Siebel will take you to a Gantt Chart View : "FS AxGanttChart View", where the availability of the agent can be seen in a nicely rendered chart.

 

 

 

Then the Activity can be dragged and dropped into the Gantt Chart applet above. I was trying to move this vanilla functionality into the end of a custom TBUI, and I pulled the top applet "FS Dispatch Board Gantt Applet" into the TBUI.

 

Compiled, and tested.

 

 

Bummer !

 

Gantt Chart applets do not get rendered properly in the TBUI. It breaks the layout completely.

 

 

I guess I'll just have to add this to the list of things I hate about Siebel.
