In moving a project over to Project Wonder, I'm happy to say that things are going very smoothly. Today I've come across an issue with this code:
EOEnterpriseObject pgEO = (EOEnterpriseObject) currentTrial.valueForKey("programGrouping");
String programGroupingStr = (String) pgEO.valueForKeyPath("displayName");
return programGroupingStr;
Previously when pgEO did not exist, (a valid result) the code would continue to run and I'd simply get null in programGroupingStr. The value for the pgEO after line one is this:
{values = {programGroupingId = <com.webobjects.foundation.NSKeyValueCoding$Null>; displayName = <com.webobjects.foundation.NSKeyValueCoding$Null>; bixidentity = "null"; }; this = "<com.webobjects.eocontrol.EOGenericRecord 7e6bc5aa _EOIntegralKeyGlobalID[BIXProgramGrouping (java.lang.Integer)0]>"; }
Now using Project Wonder, the value of pgEO becomes:
<er.extensions.eof.ERXGenericRecord pk:"0">
and when trying to execute the second line:
ObjectNotAvailableException: No er.extensions.eof.ERXGenericRecord found with globalID: <BIXProgramGrouping: [programGroupingId: '0']
What is the best way to deal with this scenario?
