InfoPath Dev

hi
I have two sharepoint form libraries.
First has column itemID.
Second has columns itemID, itemDescription.
In first library saved file with itemID=1.
In second library saved files with (itemID=1, itemDescription="QQQ");
(itemID=1, itemDescription="WWW").
Firts library created from infopath by publishing form template. This form
template by default has only primary data connection with one datafield -
itemID.
When I open first library file from sharepoint I want to display on form
also all items from second library that have corresponding value of itemID
column.
I try to add repeating table on form and add secondary data connection.
In preview mode I see all appropriate items, but are absent when I open form
from sharepoint.
How can I design form template for display one item from main form library and all
corresponding items from related form library?

...when I bind repeating group from secondary data source to master/detail repeating table, this table lose its master/detail property!
Its means that only primary data source groups can be bindind to the repeating table with master/detail properties? 

thanks

Its a newbie question, yes?

well, else speaking, I want to consolidate in one forn data from many form libraries, which one-to-many linked. I need display one record from main library and all corresponde records from childs libraries (not in list, entire records in repeating table).

but I dont want to use filtering on client side, that only hide uncorresponding records. I hope to find decision, whith allow me use server side filtering, when uncorresponding records stays on server.

may anybody suggest me the right way?

thanks
