Error encountered while evaluating Guided Decision table in a Business Rule Task
SubhoC
Below is the complete stack trace
Business Object : CreditScore(currentScore, colorCode)
process variable : creditScore
Guided Decision table - sets the value of colorCode based on the ranged of currentScore value
Business Rule task input and output variable name has been kept same
After the business rule task, I have a gateway with 3 outgoing connectors with java expression on it.
Connector 1: return creditScore.getColorCode() == "Red";
Connector 2: return creditScore.getColorCode() == "Yellow"
Connector 3: return creditScore.getColorCode() == "Green"

Thanks Maciej for the input. I already figured out that name of both input and output variable should be same but document and your previous video misguided me.
Despite having the same name of input and output variable did not resolve the issue as the Java expression associated with the outgoing connector required using Kiefunction to evaluate outcome in the script editor not using just the getter on the the process variable object as suggested in your video.
Please don't get me wrong but lack of proper document actually took me long to implement the most obvious feature.
I appreciate your kind and quick turnaround but it is high time Redhat takes some time to work on the documentation. Can you please share with me the appropriate blog site so that I can document the steps for the community.
Once again thanks for the kind collaboration. I am glad to figured out the issue last night as it was painful for me to keep it open until Monday :-)
Regards,
Subho

Which blog article you are referring to here. I followed first 6 steps, could not find any such instructions. May be I had misguided by another blog not having correct information.

In 6.2, apart from java primitive type which is not at all relevant for guided decision table, you must use Kiefunction else you will run into compilation errors. Your first 6 step video also referred to person object but had no reference of Kiefunction.
