Query for Multiple Rows as XML

Question

Ok I've seen this topic in the forums, but have failed to get this to work within my process. Basically I have a process that has a user fill out a form, and upon submittal the form writes it's information to a database (via a data connection within the form that invokes a separate process upon submittal.), once this is done the main process is invoked and it's first step is to query that same database and bring back the data in a lower (now exposed) portion of the form that contains certain fields that track the issue history. The query brings back the xml document and I store it in an xml variable (xml_output). I then take this information and use the Set Value object to assign the returned nodes values to the location fields in the form. This works if the query returns only one row. But once the form is moved beyond the initial Task Assignment, (first user), and query returns more than just one row, the added nodes to not show up on the form, i.e I still just get information about the first row in my form. From what I've read the form should be able to recognize the xpath expression, and bring back all the nodes, by in a sense using instance manager to create an instance for each node on the form. My question is how can I get this to work. Jasmin if your still out there... Help!
Also We're using Adobe LiveCycle ES 8.0
created the process using Workbench
the form was reader enabled and saved as a dynamic PDF.
Thanks

Ok have done the binding of the schema to the form, and I'm getting the information to flow as it's supposed to.  The problem I'm having now, (I know I'm having a bunch.) is that once I've placed the form into my process, and I use the set value operation to pre-fill information I get the form to flow, but the rest of the information that was previously filled in is blank.  So I have checked the variable and nothing wrong there.  It appears the problem is how I'm using the set value operation.  If I don't use the set value operation, the form retains it's information.  And if I use the set value by trying to set the subform value, the form retains it's information, but no pre-fill.  I'm going to try to be a little more detailed here.  The xml that is returned looks like this:

Flowed and positioned are actual subforms on the form that have their properties set as their names indicates.  The entire path is /form1/Page1/flowed/positioned .  The way I was able to get the form to flow correctly upon the injection of this xml data, was to bind the subforms in the form in this manner, positioned[*].  Designer didn't place the [*] for me so I had to do this myself.  But once I previewed the document, the form pre-populated and created the necessary number of subforms and placed information into the fields correctly.
Now on the process side, I have created an xfaform variable that stores the form (bound to xsd.)  information, and another xml variable that stores the query return that looks like the xml listed above (has an xsd associated with it for navigating xpath).  My first operation performs the query (JDBC- Query Multiple Rows as XML) and stores it into the xml variable.  The next step of the process is the Set Value operation which is supposed to inject the xml data retrieved from the query into the form.  Initially I tried the an xpath similar to the following:
/process_data/object/data/form1/page1/flowed/positioned = /xml_data/flowed/positioned.
No dice.  On this one the form retains the information filled out by the user (didn't explain this earlier, the form is filled out first, and upon submittal the process starts.), but doesn't pre-populate the bottom part of the form.  Next I tried the following xpath:
/process_data/object/data/form1/page1/flowed = /xml_data/flowed/positioned.
This time it retained the form information which was filed in by the user, but the bottom part is becomes hidden!  Didn't understand this.  But I started to kinda think that I had to navigate he xpath in order to correctly inject the xml into the form.  That being said my next attempt was:
/process_data/object/data/form1/page1 = /xml_data
My thinking was that if on location, I stop at page1, the xml in the variable will allow it to navigate correctly through the form.  Well it worked, but too well.  The top part of the form is blank, but the bottom portion is pre-populated correctly.  Now I'm stuck.  Not sure how to get the rest of the information in the form.  I thought about creating variables form each of the fields and then re-populating them after the injection of xml, but that didn't seem practical.  I'm almost positive it's something I'm not doing correctly with xpath.  Anyway, thanks for all your help on this.
