Set tCombobox=..%GetComponentById(pComboName)
Set tCombobox.valueList=%session.Data("Codes")
Set tCombobox.displayList=%session.Data("Display")

This is part of an instance method. 

The exact error is: Method or Property '%GetComponentById' does not exist in this class. 

Yes, that was a typo on my part. %GetComponentById is being used in the parent class. 

You see, when I try to call it with ##super I get "method does not exist in any super class" 

The line that's giving me trouble is: 

Set tCombobox=..%GetComponentById(pComboName)

I'm basically trying to pass a class parameter into the GetComponent so it can be used in a variable. 

The parent class uses the GetComponentById without an issue so I can't figure out why I'm getting the "not present in class" error.
