<sigh> another regex question

[Bob Sneidar]

Hi all. 

I am trying to filter a list without integer numbers. Note that matchText(tControlNames, "[0-9]+") returns true, so the regex pattern IS working, but filter lines of tControlNames without "[0-9]+" does not filter out the lines with integer values, neither does filter lines of tControlNames not matching "[0-9]+". 

Where am I going wrong?
