Hi Igor,
I adpoted your "properties" approach and it works well in VCO 5.1, however, when I improted the same workflow into VCO 4.2 it failed.
the error is "ReferenceError: "storageProps" is not defined. (Dynamic Script Module name : getStorIpByStorIdAndStorProps#17)"
storageProps is the attribute of type "properties" that I use to carry information throughout the workflow, however in vco 4.2 it seems to be lost right after the workflow leaves the the script task where it's created (using "new Properties"), thus when I try to use this attribute even just in the immediate following script task, I get the error shown above.
Again, the same worfklow works fine in VCO 5.1. Our product needs to support both 4.2 and 5.1 and this is blocking our product release, please let me know if you have a solution to this, thanks!
