Hi,
I was trying to compile this simple rule using alias from an example given in OPM user guide.
the person (the colleague) is a member of the person's co-workers if
the person's workplace = the colleague's workplace
I have declared the following in properties file
1. entity named person
2. relationship of person with itself called 'the person's co-workers'
When I compile it I get the following error ::
Error after text 'the person's workplace = '. Found text: 'the colleague's workplace'. Expected value: variable,constant (OPA-E00111)
Please help.
