Michael,
ThankYou for your speedy feedback.
Is it possible to count the number of fact types in a drl if not in a Guided decision table editor ?

It is not possible with the web guided decision table at this stage as you need to use "collect" as you rightly suspect.
We have numerous improvements to complete to make the web editor more powerful.

Hi,
How can I count the number of facts of a partilcuar type inserted into the rules session?
lets say, I insert several instances of fact called Asset into the rules session.
I need to write a web guided decision table that outputs a specifc text value in an action column based on the number of assets in memory.
numberofAssets result
1 result12 result23
result3
How can I create a condition column that counts the number of Assets in memory ?
question2:
If I want to write a drl that needs to count number of Assets in memory and print that value, can I use a collect from or is it only used with a Collection ?
As always ,
Thank You all for your fast responses and ideas.
Thanks,
Ram
