> When modeling spreadsheets for form/spreadsheet validation, see the attached screen shots, all of the tools use the convention of A, B, C for the column names (Open Office, Excel, and Numbers). When trying to create an object with variable names of A, B, etc, I get errors in the JBDS as the below:
> Description Resource Path Location Type
> BuildError: Unable to create Field Extractor for 'A' of '[ClassObjectType class=com.sample.SimpleSpreadSheetBasedPOJO]' in rule 'Validation 1' SimpleSpreadSheetBasedTest.drl /BugProject/src/main/rules line 16 Drools Error
> No amount of massaging can get this error to go away.
> When I run the attached classes, I get the following error message:
> Unable to create Field Extractor for 'A' of '[ClassObjectType class=com.sample.SimpleSpreadSheetBasedPOJO]' in rule 'Validation 1' : [Rule name='Validation 1']
> java.lang.IllegalArgumentException: Could not parse knowledge.
> at com.sample.SimpleSpreadSheetBasedTest.readKnowledgeBase(SimpleSpreadSheetBasedTest.java:48)
> at com.sample.SimpleSpreadSheetBasedTest.main(SimpleSpreadSheetBasedTest.java:23)
> Even though a getter and setter method is available.
> So I created an ID field, this seems to work fine, but if I create a field A1, this does not, if I create ID1, this seems to work...so something is amiss in the way in which fields, methods, etc are marshaled.
> If a Java Bean is required that is fine, but then we need to retreat from marketing POJOs as facts, and also possibly create a better error message that tells us to use Java Beans and not POJOs.
