The function ecm:coalesce returns the first not null argument from a specified list of arguments.
Example
An expression checks specific attributes and a related data set for values. If any of these sources contains data, a personalisation is inserted into a message. Rather than write an InsertIf statement to check each source, a single expression is used:
<%InsertIf expression="${ecm:coalesce(user.CustomAttribute['product ID'], group.CustomAttribute['conversion date'], user.relatedAttribute['Purchases'])=='notempty'}%>Text<%/InsertIf%>
