%GetComponentByID Compile Error

Paul Dawson · Feb 24, 2020

Hello,

I have a class I'm working on that is extending a base class that contains the %GetComponentByID method and a section of the new code I'm writing uses %GetComponentByID but when I attempt to compile the class I'm getting an error that says the method doesn't exist.

Am I missing something to be able to include the GetComponent method in an extended class?

What happens if you use %page.%GetComponentById?

Do you want to call %GetComponentByID of a parent class?

You can do it like this:

set result = ##super(args...)

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.

%GetComponentById and GetComponentById are different methods.

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

Share a code sample please?

One other thing: both methods should be either methods or classmethods.

 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.
