Re: Witango-Talk: methods calling methods

[Dale Graham]

Well, I'll have to check this out again (I've had so many different  
versions of the editor lately that I don't know if this is still a  
problem) but I can assure you that I did have at least one version of  
the editor that pulled it in as a method scoped "this" - and when I let  
it stand that way, the tcf definitely no longer functioned. Again, this  
might just have been a problem with that particular version...  And  
I've also been bouncing back and forth between the Witango server and  
the J2EE server, so cannot recall now on which I had the problem... I  
have just been explicitly setting the internal methods ever since to  
the scope of the instantiated object and that's worked well. But if  
it's overkill I'd like to drop back to something simpler.

I have tafs and tcfs that would disagree with this statement.

And if instantiated in any other scope, the called internal method   
needs to match scope of instantiation. At least that's been my   
empirical experience.


when using "this" as the object name,  the scope should be irrelevent.  
 the "this" keyword implies that you want to call the method of the  
exact same instance of the method that is currently running.  Method  
makes the most sense to me, because your are currently executing a  
method, but Instance$this would probably make more sense.

However, what I've documented in my previous email is how the two  
versions differ, and the Witango one definitly has "pain in the butt"  
potential, because dragging a method to a called within a tcf method  
by default will not work unless you explicitly fill in the name as  
this.

This (no pun intended) is a step backwards.
