BPEL 11g - Error using FileAdpter + loop while

Question

Hi
I'm using FileAdpter to read some files, each file contain between 50 and 150 records, after the adapter reads records and transform the msg, the payload is send to a Bpel Proccess.
My Bpel iterate over the records using a while activity, the problem happens when the numbers of records is grater then 91, my composite never finish, and appear Running status in console.
Inside the while activity i put the ora:getElemnt(node, index) to retrieve the current row, if a just place a static value inside the loop it's run perfectly, but using getElment or /someXpath[$index] the bpel never ends.
Should i have to config in Bpel server to work with large documents ?
(sorry for my poor english) :)
Any ideas guys ?

Hi Klemp,
No need of configuring the server.
11g can handle giga bytes.
I think in BPEL activities expressions $index will not work.(as of my knowledge these works in XSLT only, I mean $var and exists() function these kind of things..), You have to use like bpws:getVariableData("Index") insted of $index
you can define variables and you can use them as indexes while retrieving data.
Like
<assign name="AssignIndexAndCount">
      <copy>
        <from expression="ora:countNodes('MyVariable','PartName','/ns1:Var_Input/ns5:Id')"/>
        <to variable="CountActivities"/>
      </copy>
      <copy>
        <from expression="'1'"/>
        <to variable="Index"/>
      </copy>
    </assign>
<while name="WhileName"
           condition="bpws:getVariableData('Index')&lt;=bpws:getVariableData('CountActivities')">
      <sequence name="CraeteOrderNotifications">
        <assign name="AssignIndexes">
            <from variable="inputVariable" part="payload"
                  query='/ns3:MyEBM/ns3:DataArea/ns3:Var1/ns4:PersonDetails[bpws:getVariableData("Index")]/ns4:PhnNumber'/>
            <to variable="varIndex2"/>
          </copy>
        </assign>   
        <assign name="IncrementIndex">
          <copy>
            <from expression="bpws:getVariableData('Index')+1"/>
            <to variable="Index"/>
          </copy>
        </assign>
      </sequence>
    </while>Regards
