Hi all
I am using the Send Message Even present in the escalations of the user input task. The message isn't sent when I use the rules/ expressions (with process variables as inputs) to set the value of custom properies. But the message is being sent when I use the hard coded content.
Could any one let me know why is this happening?

TIA...
