Re: Witango-Talk: Branch Question

Just tested it, and it worked fine. ;)

Chances are the Object Instance Variable is incorrect in the "branched to" taf

The introspection error is typically caused by trying to call a method of a non existent object instance... Perhaps you should try rewriting

<@callmethod request$Common 'SelectShippingrequest(<@var request$FreeShip>)'>

as

<@CALLMETHOD OBJECT="Common" SCOPE="Request" METHOD="SelectShippingrequest(<@var request$FreeShip>)" METHODTYPE="invoke">

That's what my callmethod looks like in the example i've attached.

I've attached the 3 files i used to show that this works fine on 065

This is incorrect.... Request scope is valid for the entire "REQUEST" branching doesn't start a new request scope.

Request scope is local to the TAF and I don't think it can cross branch
actions?
Try USER scope

If you instantiate a tcf object in a taf, and then branch to a taf (branch and return), do you have to instantiate the same tcf object again in
the
branched taf in order to perform a <@callmethod> in the branched taf?

I am getting the following error and wondering if this is the problem:

Also, what does "introspection information mean?
Error getting object's introspection information.
Couldn't find info for method SelectShippingrequest
<@assign request$Shippingrequest "<@callmethod request$Common
'SelectShippingrequest(<@var request$FreeShip>)'>" encoding=none>
Thanks
