Engine exception when reapply data on filtered dataset

Forum post

Launch the app, click Refresh button on tbar, it will just re-apply data into project.
Tried to replicate in Vanilla, no luck.
If comment resourceStore filtering, no expception will be triggered.
If set all stores data with empty array before set real data - it will also fix an exception.

Hi, no progress yet, but we flagged this as high-prio. So, things should go faster from now!

After brief investigation, it seems what happens is:

• The resource store is filtered.
• When data is loaded into the filtered store, the commitAsync is called immediately (synchronously) after
• This breaks the optimization we have for loading data into several stores, which "holds" the commit until changes to all stores are written, so commit starts in the middle of data loading
• This somehow rejects the ongoing transaction (from the previous ongoing commit - this part is not clear) and triggers those errors

Probably will need to coordinate the filtering after data load with the data load optimizations. Investigating further.
