messages.log

After trying to continue to go about my business after this, the IDE keeps firing java.lang.AssertionError messages at me.

the proper messages.log file. The other is not the right file.

Uploaded the wrong log the first time. messages.log is correct, messages.log.2 is not.

Can you provide a fragment of your code and exact description how you changed the variable name? Thanks

I think, specifically, the problem occurs when changing the the variable name of the object that you're iterating over.
This issue also occurs with the fori template.

Example

private LinkedHashSet<String> newAvailable(DefaultMutableTreeNode selected)
{
        fori
}

expands to (actions is an instance variable String array):

private LinkedHashSet<String> newAvailable(DefaultMutableTreeNode selected)
    {
        for (int i = 0; i < actions.length; i++) {
            String string = actions[i];
            
        }

    }

I hit tab to accept that i is my counter, and now actions is highlighted so I can change it. I try to start typing to
change it to selected.getChildNodes(), and when I do that, it throws the errors, and the editor goes to heck.

log for fori crash

Should have said "selected.getChildCount()" in my previous message.
