Getting "Collection was modified; enumeration operation may not execute" errors on branch creation

[Aaron K]

This is started happening yesterday. When I make a child branch of our main I will sometimes get the error above pop up in a dialog. Everything seems to work but I am a little concerned.

Any ideas? Should I be terrified?

I've gotten this occassionally after upgrading to 4.1 as well, it seems fairly harmless and everything just progresses normally after I dismiss it. I usually see this inside visual studio, are you seeing it in the GUI?

[Aaron K]

Hi there. Yes I'm seeing this in the Plastic client GUI. Googling that error code doesn't bring up plastic but some possible runtime error in other apps, so maybe it's something to do with what Plastic is written in.

We are trying to catch this issue.

We also faced this issue last week, but we are not able to reproduce consistently.

[Aaron K]

Manu, is there any debug logging I can turn on to help find it?

I had this error when updating the Branch Explorer too today, but I wasn't able to reproduce it.

Thanks Aaron, we already have the stacktrace so the next sprint we will start investigating this issue.

As coding gorilla said it's harmless and nothing regarding the branch is broken, it seems it's a drawing error.

Cool, thanks guys.

You are welcome, we'll try to fix it ASAP.
