Hello all,

I'm using a plugin in my application, everything is done. But when i check the log, there are plenty exception as shown below. The good thing is, it doesn't influence any result there, but the bad thing is as it doesn't ruin anything, I could not tell where it takes place and what caused that strange stuff.

In my plugins, I've used the many stuff as "option =  AppUtil.processHashVariable(option, wfAssignment, null, null);" to get the value by hash variable.

I'm wondering if this the cause, but i don't know how to avoid it either.

Is there ANYONE who has some ideas about this?

Thanks for your time and help!
