Using 5.4 (5.4.3) RTM designer.
Every time I run a relational model data sync all groups in the project explorer expand.
I don't believe this happened in previous versions.
Does it still occur in 5.4.4 hotfix? (We made a lot of optimizations in 5.4.3 and had to roll back one in 5.4.4 which I think will affect this)
I will check this.
BTW The description of the hotfix build seems to be incorrect.
Indeed, with the hotfix the groups don't expand after a model sync.
