Comment 12 for bug 1460616

Ok, I have tried recreating the steps and here is what I've come with:
What I did was creating a completely new script file in :

K:\SikuliX\pdi\Tests

and retyping the text in the example from first post saving after every line.
K:\SikuliX is used as sikuli home folder and runsikuli script is used from it as well.
Note that my tabs are 4 spaces and "insert whitespace in place of tabs" option is active.

I started from the beginning and when I typed
        FilterTable.clickMessage(message21)
and tried to save it it produced the error:
[error] IDE: A non-IOException-problem when trying to save null Error: null

Hope this helps to find the problem
