[Repast-interest] Runtime error with regard to watcheeFieldNames in the Watch annotation

[Zhi Z. <zz...@au...>]

Hi there

I am getting an run-time error while firing up my repast simphony model and
I am currently on version 2.0 beta. From the error stack, I think it is
complaining the watcheeFieldNames in the Watch annotation. The error only
happens on two of the three watches I have defined in my project and I
really don't know why.

The problematic watch is defined as:


@Watch

( watcheeClassName = "NGNMarketSimulation.ConsumerAgent",

whenToTrigger = WatcherTriggerSchedule.

*IMMEDIATE*,

watcheeFieldNames =

"FinishSelection",

triggerCondition =

"$watchee.CheckallCOFinishSelection()")



The FinishSelection boolean variable and the trigger method
CheckallCOFinishSelection()
have all been defined in the ConsumerAgent Class. I have compared the two
problematic watch with the one that is working and found out that the method
"repast.simphony.engine.watcher.WatcherEditor.edit" gets called three times
for the problematic watch for only twice for the watch that is working.

Any helps will be much appreciated.

Benson ZHONG.
