I am getting the following error with my sample decision table...

Getting the following error w
Exception in thread "main" org.kie.kogito.codegen.rules.RuleCodegenError: Errors were generated during the code-generation process:
[2,5]: [ERR 102] Line 2:5 mismatched input ';'
[0,0]: Parser returned a null Package

Here is the source:
https://github.com/ravim786/hayagriva/blob/int/src/main/resources/com/bluepitch/ruleapp/hayagriva/PropertyTypeCode.xls

What am I doing wrong?

Hi,

Not sure, but one thing I see is that the Unit row is added, but on the right cell next to it there is no rule unit name.

You can also try to import SubjectProperty into your XLS. It's a "blind shot", because I haven't tried it but import issues are common in rules.

Jakub.

Nothing worked. Can I have a simple decision table without ruleunit and queries?

When I remove both unit and queries rows.. it's now complaining about $l: /deriveProperttTypeCode

After going through the documentation, I fixed the decisiontable and now i am getting the following error

ParseExpressionErrorResult: Unable to Analyse Expression subjectProperty.getAttachmentType == "Detached":

Hi,

Could be that the header needs to be changed from "subjectProperty.getAttachment" to "subjectProperty.attachment".

What I do is I convert the table to DRL since I pick the errors easier that way. I used BC since I have it open here, but I believe it should be possible to just dump XLS to DRL. Maybe that helps a bit. Also depends what format you are the most familiar with.

I have uploaded the project in github : https://github.com/ravim786/hayagriva

I am trying to get a sample decisiontable working with kogito. The decisiontable fails to parse


InvalidExpressionErrorResult: Unable to parse consequence caused by: (line 3,col 90) Parse error. Found "}", expected one of  "%=" "&=" "*=" "++" "+=" "--" "-=" "/=" ";" "<<=" "=" ">>=" ">>>=" "^=" "|="

What am I doing wrong? I followed the documentation. 

Thanks for your time

Hi Ravi, could you please try to update the action

from:
$loanApplication.subjectProperty.setPropertyTypeCode($param)

to
$loanApplication.subjectProperty.setPropertyTypeCode($param);

Notice the ending ';'.

That worked. Thanks

Now to get a Resource generated, it looks like I need to define a query. 
I am trying to look for some documentation on how to define a query that will have my resource generated.
