How to call data page from when rule ?
I have a data table that represents a list of Users.
I have a data page D_Users that provides access to the data table.
D_Users takes few parameters like First Name, Last Name, Birthday and it should return the User from the data table with this characteristics.
I tested some hardcoded values in a test section, to see if the data page works correctly and it does.
How to call D_Users from a When Rule? I need to check if a user exists in the data table, in a When Rule. How can this be done?
Thanks.

Hi,
You can set the Data page (lookup) in the Pages & classes
D_MyDataLookup = MuOrg-MyApp-Data-MyClass
Then in the condition use:
- D_MyDataLookup[ID:”myValue”]
- D_MyDataLookup[ID:.myID] (as long as it is accessible in the context)
- D_MyDataLookup[ID:param.ID]
The only way I found to make the 3rd option work was to set param.ID in a data transform before executing the when rule.
Not sure if it is the best way.

When rules and parameters don't go along with each other very well. If you have a hard coded value D_MyDataLookup[ID:ABC].Value>0, use when rule otherwise, use a data transform and use an expression like D_MyDataLookup[ID:param.ID].Value>0
