I've got an NSArray var, custInfo, which fetches an array of objects via a
direct action:
custInfo = ec.objectsWithFetchSpecification(fetchSpec);
It then loads a component page passing the array:
ResultPage nextPage = (ResultPage) pageWithName("ResultPage");
nextPage.takeValueForKey(custInfo, "CustInfo");
return nextPage;
On ResultPage I can access a single element of all obj arrays by setting
it's value to a property:
CustInfo.cust
But, how do I access a property of a single row? I tried this, but it throws
an exception:
CustInfo[0].cust
Are you familiar with WORepetition? Alternatively, you may want to
investigate the use of WODisplayGroup.
I believe your first example above actually returns an array (NSArray)
of that particular attribute. How are you displaying that?
