CSS PropertyValueEditor calls index in EDT which ends in URLMapper.findFileObject().

This is a known issue. The children of the StructureItem can't be computed in advance and once the CSL infrastructure asks for them, they need to be synchronously computed and returned.

I do not remember all the aspects now, but we tried to resolve the performance issues with Svata some time ago and this was a compromise. 

It looks like I can't do much to resolve this problem - either the CSL won't call getNestedItems() in EDT or the whole API needs to be redefined to better support the needs.

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
