In other words, moving the view caused it to load at a slightly different time in program execution which was (apparently) a time when the datapath had been linked with a data set. It's good to know that your code is working! However, if you want to ensure that it will *always* work as expected, you might want to wrap the code's initialization inside of an ondata event handler as described above. Cheers! :) -Rich Hi Tim,

WTF? :) I actually just ran into this error and it turns out that the simple fix was moving my view that generated the error out of a library file and into the main file — I changed nothing else.

Despite being a a member of the OL team when this warning emerged, I never understood it, either. Now I'm working on a OL app for a client, and the first answer in my googlechase was this entry. Way to go! ROTFL! Despite being a a member of the OL team when this warning emerged, I never understood it, either.

Thank you very much for this tip. My code works fine now! =) [ simon.cpu ] I spent hours racking my brain why a simple call to this.datapath.getNodeText() gives me “p is null in Datapath”, even though it works inside .
