I was reading somewhere that by using the symbolic reference character in workflow i.e. "%"; One is able query what the current value of data items may be at the time of a particular activity.
I tried this out just as a test in buildtime. Using the Workflow Native-Client(Fat-Client), I was however, not able to determine the value of the data items I was querying.
Below is the symbolic reference syntax I used in BT
% Variable Name1 %
% Variable Name2 %
% Variable Name3 %
Am I missing something obvious like quotes before and after perhaps?
Also is there a known limit to the number of symbolic references one can put in the description field.

I havent tested it but I dont specify a blank space between the '%' and the variable name. If my d/s is VAR_1, I would specify %VAR_1% in the description and it always works. Give it a shot.

I just tried that with and without the space, but no luck 
All I see is some like this...
Do you think it's possible that if the data item does not have a value stored in it yet, workflow simply puts something like what's above instead of perhaps returning a null value?

I believe it should return a null vaue if the field is empty.
If you you D/s looks like this :
Datastructure Person
member string FirstName
member String LastName
END PERSON.
Then to display the info you have to specify it like this
%Person.FirstName% and %Person.LastName%.
If you are trying to display it in the 'documentation' space it wont work. You should be able to use it in the 'Description' space.

if u try the following in the "DESCRIPTION" field
|%name1%|%name2%| with name1 = "Mac" and name2="" or null
then it will appear as
|Mac||

This worked. I'm not quite sure what it was. After I took out the spaces from the description field and re-imported into runtime, I was able to see values ONLY after a native client restart.
At anyrate, thanks a bunch!
