Ups, didn't know it was missing. :-(
My IDEA gets totally scre... when dealing with a lot of annotations.
It's commited now.
btw: is there a SVN function that could help me in these cases - to find other potentially missing files?
svn status | grep \?
will show you unadded files.
They both have status functionality.
In TortoiseSVN they have "check for modification" in the right click menu, third choice from the top
In IDEA, There is "Check Directory Status" in the SVN menu, if you choose check against server you get what is changed on the server from what you have, to what you have changed.
Also, at the bottom of the screen there should be a "#9. Changes" that if you click on it shows what has changed. It also gives you the ability to group your changes so that you can say have three JIRAs going that don't overlap, and put changes for each JIRA into it's own group, then you can choose to commit just one group and all the files for that JIRA will be commited.
