Integration

Hello everybody. I have Jdeveloper 11g with SOA installed, so within the BPEL i have a loop While from 1 to 3 (just to try).

So i want to create a Child Node on the fly counting from 1 to 3 nodes. For the input (which is useless) i have:

  <xsd:element name="numero" type="xsd:int"/>

For the output i have:

<xsd:element name="repeticion">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element name="palabra" type="xsd:string" maxOccurs="unbounded"/>
      </xsd:sequence>
    </xsd:complexType>
</xsd:element>

Inside my bpeel i have a var "loop" which counts from 1 to 3.

    <assign name="Assign1">
      <copy>
        <from expression="0"/>
        <to variable="loop"/>
      </copy>
    </assign>

A while loop and the concat Hello 1 -> Hello 3:

<while name="While1"
          condition="bpws:getVariableData('loop')&lt;=3">
      <sequence name="Sequence1">
        <assign name="Assign2">
          <copy>
            <from expression="bpws:getVariableData('loop')+1"/>
            <to variable="loop"/>
          </copy>
        </assign>
        <assign name="Assign3">
          <bpelx:append>
            <bpelx:from expression="concat('Hello ',string(bpws:getVariableData('loop')))"/>
            <bpelx:to variable="outputVariable" part="payload"
                      query="/ns1:repeticion/ns1:palabra"/>
          </bpelx:append>
        </assign>
      </sequence>
    </while>

But when run it returns <palabra>Hello 1Hello 2Hello 3</palabra>  instead of <palabra>Hello 1</palabra><palabra>Hello 2</palabra><palabra>Hello 3</palabra>

Where am i wrong?.

Best regards.
