I am having problems writing an expression rule that uses displayvalue() function.

I have an array CDT called BusinessRulesCDT. It keeps erroring out complaining about the 4th argument to displayvalue() which is the default value.

At run time, it gives the error message:

Details: ERROR:An error occurred while evaluating expression: businessRule:rule!findBusinessRuleCDT(pv!businessRuleArray, pv!ruleName,pv!defaultBusinessRule) (Expression evaluation error in rule 'findbusinessrulecdt' at function 'displayvalue' parameter 4: ) (Data Outputs)

My BusinessRuleCDT is:
- id (integer)
- name (text)
- value (text)

my expression rule is:

findBusinessRuleCDT(businessRuleArray (Any Type), ruleName (Text), defaultBusinessRule (Any Type))
which calls ==> displayvalue(ri!ruleName, ri!businessRuleArray.name, ri!businessRuleArray, ri!defaultBusinessRule)

For the 4th parameter, I tried {}, "", and even the example above where I pass ...

I tried placing {}, "", and finally passing into my expression rule a default value where I pass in a pv of that CDT type. Even that blows up with the same exact error on the 4th parameter to the displayvalue() which is the default value argument.

It only seems to work if I use displayvalue() straight on instead of abstracting it away in an expression rule.
