Displaying data in Gantt chart applet with 2 applets with active cache

Experts,

We have a customer who wants to have two Gantt boards (one for scheduling activities, the other to dispatch them) each one one with a different X-SearchSpec.

As part of a proof of concept, we cloned the vanilla applet "FS DB Planned GanttChart AX" but when testing the solution we found that it was behaving a bit oddly:

- When accessing the first of the boards, the data retrieved belonged to that particular board (so far so good).

- When navigating to the second board (within the same user session), the data shown was the same as before.

We found that the only way to avoid this behaviour was to turn off the board's cache (FSDB - Activity Cache Service user property) but the performance impact on the database side would increase significantly.
