WL821 error, when executing customized user decision

[Garcia, Carlos]

Hi Philip:
=20
I used a copy of TS40007902, and this time the decision works jut fine.
I also tried your advice about deleting the bindings but it continues =
giving
me the same error.
About the OSS note you're talking about seems to be 0155129 Single step
task: binding can not be deleted.

If you define a new single step task and switch to the binding between  =
=20
task container and method parameter container, then binding is =
displayed=20
even if there had previously been nothing entered or something had been =
=20
deleted.                                                                =
=20
This binding is automatically created in the change mode.               =
=20
This underlying binding generation also occurs for a copy of the =
generic=20
decision task (TS8267), however, the work item is not executable and    =
=20
will produce an error.                                                  =
=20
This binding is not needed in most of cases, because, if no binding was =
=20
defined between task and method, the container is completely copied. If =
=20
all elements of the task container resulted automatically when you      =
=20
entered the object method, they are identical and copying the =
containers=20
is harmless.                                                            =

Solution                                                                =
=20
To delete the binding completely as to allow the container to be copied
 
choose "Binding" =3D>"Delete" in the Binding Editor menu.
 
It should be noted that this operation is not possible for method
 
parameter containers with mandatory parameters.
 
It should also be noted that binding is repeatedly regenerated when you
 
call the Binding Editor in the change mode.

Hi Carlos,=20
 
You have to delete the all bindings (even if just spaces) with the =
object
method=20
using the delete function key. Any other way will not delete the =
bindings.
Every=20
time you view the bindings in change mode, you have to delete them =
again!
There is=20
an OSS note on this somewhere, and for this reason I guess the 4.6D
documentation=20
says not to create decison tasks by inserting the object into a new =
task,
but by=20
copying the standard task.=20
 
I lost many days trying to solve this one when I first met it.=20

Hi everybody=A1=20
 
I=B4m working on a Purchase Requisition Workflow (4.0B) with a =
customized user
 
decision (copy of TS00008267). Everything goes fine, the workitem is =
created
 
in inbox of the right person showing in the workitem description the =
BUS2009
 
attributes. But when I try to execute it, only changes the status from =
READY
 
to IN PROCESS, Checking the workitem history shows a WL821 error =
(unable to=20
execute method PROCESS from object DECISION). I already revised the OSS =
 
notes but i didn=B4t find one, which could solved this problem. The =
weird=20
thing is that if I use the standard user decision, it works.=20
 
Any advice or guidance will be very appreciated.=20
 
Best regards.=20
