[rules-users] How to count number of facts of a type in memory?

[puja nandamuri]

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
