Error in the evaluation of expression..." with empty attributes

[Schmidt, Jake (SN)]

Akshay,

To extend on Mike's example I've had this happen at a &ZOBJ1.ATTR& (just
one subtype, not 2).  This was happening on a couple material master
attributes (BUS1001006) that were created from classification data
(function module to read those in).  My fix was to use a container
operation to bind &ZOBJ1.ATTR& into the WF Container as a stand alone
element.  
At runtime the WF doesn't error out if the WF Container element is empty
as opposed to the object type.

I've always assumed it had something to do with how our consultant set
up those virtual attributes.  I've never fixed it since my non-elegant
work around works.  If your problem is similar and you do fix then
please share!

Thanks

Akshay, 

 

Most likely your top object is not instantiated. Another option is if
you're using an attribute of your attribute object then the 'middle'
object cannot be empty. 

In other words, for a binding like &ZOBJ1.ZOBJ2.ATTR&, both ZOBJ1 and
ZOBJ2 must be instantiated otherwise WF will error. 

 

Cheers, 

Mike

Hi All,

 

Has anyone seen problems in assigning empty attributes?

It's working fine in dev: I am using an object attribute with an object
type in condition step.However once transported to QA its all falling
apart with "Error in the evaluation of expression ....." .

Actual message seen in the log is : 


Error in the evaluation of expression '&ZWF_OBJ<???>.ManualApproval&'
for item '8'


I guess similar problem was faced by Mike Pokraka .. but I could not
find answer to the thread..

 If Mike or anybody has any clue to the same could you pls suggest what
needs to be done?

 

  

Thanks and Regards, 

Akshay Bhagwat
