Hi all, I tried adding a simple derived attribute to a model, as shown here:
http://idisk.me.com/kelleherk/Public/Pictures/Skitch/derived_attribute-20100226-125124.jpg However EOF falls over as soon as I touch that entity with an error like the following. This is WO 5.3.3 btw. Looking at the source in EOSQLExpression, it would seem that the attribute_definitionArray is null, because if it is null, then the method tries to get a column name and throws this exception when there is no column name.. The eomodel itself shows the attribute like this in the plist: { allowsNull = Y; definition = oid; externalType = INT; name = uniqueID; valueClassName = NSNumber; valueType = i; } So now I put a few statements in didFinishLaunhcing to grab that EOAttribute and check in the debugger and I find that the _definitionArray is empty. That does not seem right, does it? http://idisk.me.com/kelleherk/Public/Pictures/Skitch/emptydefinitionarray-20100226-131150.jpg Any ideas why this would not work, or how to troubleshoot it if it should work? I know Wonder uses programmatically created derived attributes for COUNT(*) and aggregate functions, but is there anyone out there using model-defined derived attributes successfully? java.lang.IllegalStateException: sqlStringForAttribute: attempt to generate SQL for attribute 'uniqueID' on entity 'CTMessage' with undefined column name. You must define a column name for this attribute before attempting a database operation. at com.webobjects.eoaccess.EOSQLExpression.sqlStringForAttribute(EOSQLExpression.java:2064) at
