  • Can't get the flowloader sample application working

    Hi all,

    I'm messing around with PR3 and I'm having a bit of trouble getting the flowloader sample application running correctly. At first, it wasn't working at all when I clicked on any of the links or buttons on the sampleA page, but then i realised that I didn't have the OGNL library in my classpath. After downloading and including it, everything except for the launching of sampleB as a sub-flow works. When launching sampleB as a sub-flow of sampleA, I get the following stack trace:

    Code:

    Have I missed something?

    Sorry, I meant "flowlauncher", not "flowloader".
