Hi James,
To re-use a Method inside another Method - which happens to belong to the
same TCF:
Note: Re-instantiating the Object is not necessary.
-- Drag the Method into the Method:
-- Set your 'Object instance variable' to:
Scope: Method
Name: this
Or if you want to the <@CALLMETHOD> Metatag:
<@CALLMETHOD OBJECT="method$this"
METHOD="someMethod('parameter1','parameter2')">
The variable 'this' automatically refers to the current Class (TCF), and
because you are inside a Method - Method Scope is used.
Just be careful about doing this inside your On_Create Method - because then
your TCF is going to call itself before it has finished loading the first
time.
Hope this is what you are looking for. Cheers...
