Filtering a repeating table linked to a secondary datasource

Question

I have an infopath form based on a sharepoint list (worktracker).

In that form there is a repeating section which holds data from a secondary source which is the worktracker list again.

I would like to filter that table using the value in a field on the form - this enables me to run a check on duplicate items on the list by using a calculated checking reference.

I have done this by using conditional formatting to hide the non-matching items but that this killing my form as IE throws tantrum as it takes too long.

Does anyone know another way to do this? I am stuck using IE8 - not my choice!

UPDATE:

So since posting the above, I had since tried using a REST connection which doesn't work as my list is too big. I have also tried using an XML connection to a filtered view and that didn't work either!

Cheers,

In the form, select the value field. Create a rule that sets the secondary data source's query field of the same name to that value. Then query the secondary data source. It will only return the items where the value matches.
