kabootit[Tip] Target an error fast
When you get an error in a method, an error box pops up with a description of what Servoy doesn't like. An example would be "org.mozilla.javascript.EvaluatorException: The undefined value has no properties. (REC_nav_label, line 7)." Notice that the method and line number are given for you.
A fast way to jump right to that line of code is to turn on the Servoy debugger. Don't open any methods or set any break points. When the error occurs now, Servoy will pop open the debugger, open the correct method and put an error next to the line of code that is not working.
One more reason to love Servoy's ridiculously powerful debugger....
