we are using Intellij for same project since version 8. Spring facets and the validation of xml files worked great in 8 and 9. In version 10 though things became complicated. I tried with manually configuring facets and with auto-detection and sometimes it works and sometimes not but the settings are always lost after Intellij restart, I think at least. Its hard to describe since the behaviour seems to be random, the only thing that stays constant are the read lines in the xml files after some time
Once I got it working after setting it up manually and everything was green again. But it took me like 15 minutes and changes were lost after restart again (auto detection disabled). I really dont know what to do here.
What I also recognized is that .iml files are removed at startup and then they are added again, maybe it is related, is this kind of settings stored in the .iml files? That would explain the reset.
I just did restart and I see the red lines and also the message Spring facet is not configured for module ... which is very frustrating since I added the configuration 1 minute ago
