How to query more than one type objects using a webject in windchill PDMLink?

Hi,

Someone can help me on this. I will appreciate it.  I want to query two type objects using webject. I found the article CS195365 from PTC support, which has an example:

• Example:

<%@page language="java"%>
<%@taglib uri="http://www.ptc.com/infoengine/taglib/core" prefix="ie"%>
<!-- get wtproperties -->
<ie:webject name="Get-Properties" type="MGT">
<ie:param name="ATTRIBUTE" data="wt.federation.ie.VMName"/>
<ie:param name="GROUP_OUT" data="properties"/>
</ie:webject>

<ie:webject name="Search-Objects"    type="OBJ">
<ie:param name="INSTANCE" data="$(properties[0]wt.federation.ie.VMName[0])"/>
<ie:param name="type"    data="wt.part.WTPart"/>
<ie:param name="type"    data="wt.epm.EPMDocument"/>
<ie:param name="type"    data="wt.doc.WTDocument"/>
<ie:param name="ATTRIBUTE_TYPE_CONTEXT"    data="wt.fc.Persistable"/>
<ie:param name="where"    data="(containerName='<CONTEXT_NAME_HERE>')"/>
<ie:param name="attribute"    data="number,name,version,lifeCycleState" delim=","/>
<ie:param name="group_out"    data="objectsSearched"/>
</ie:webject>

But I tried it. I got the error.

Here is my code;

<ie:webject name="Query-Objects" type="OBJ">

  <ie:param name="INSTANCE"  data="localdomain.vm-windchill.Windchill"/>

  <ie:param name="authorization" data="$(@SERVER[]AUTHORIZATION[0])"/>

  <ie:param name="type"   data="wt.part.WTPart"/>

  <ie:param name="type"   data="wt.doc.WTDocument"/>

  <ie:param name="where"   data="(number='$(@FORM[]number[0])')"/>

  <ie:param name="attribute"  data="name,number,version,lifeCycleState,checkoutInfo.state,containerName,type,obid,containerID" delim=","/>

  <ie:param name="group_out"  data="objectsSearched"/>

     </ie:webject>

  <ie:webject name="Sort-Group"  type="GRP">

  <ie:param name="GROUP_IN"  data="objectsSearched"/>

  <ie:param name="SORTBY"   data="name"/>

  <ie:param name="GROUP_OUT"  data="objectsSearched"/>

</ie:webject>

Here is the error I got:

javax.servlet.ServletException: com.infoengine.util.IEException: Query-Objects: Parameter "TYPE" may only be specified 1 times.
