Apologies if I am asking a stupid question here, but here is my scenario:
I have a custom object, say A, which has two lookups:
One to a standard object (Lead) and,
Another to a custom object, say B.
The name of the two lookups on A are B__c and Lead__c.
Now, on the related list for A on Lead's page-layout, how can I show the fields belonging to B? Is it even possible? The user interface doesn't seem to allow me to do this, but I was trying to use something like:
<relatedLists>
<fields>B__c.some_custom_field__c</fields>
<relatedList>A__c.Lead__c</relatedList>
</relatedLists>
in the layout metadata file, but it doesn't work. I get a message that says something like:
Invalid field in related list...
Thanks in advance!
