How to use attachments by custom

Hi,

I make custom actionModel.xml and custom action.xml.

by  DocumentManagement-actionmodels.xml, DocumentManagement-action.xml "COPY & PASTE".

And make

<model name="CustomInfoPageTabSet" resource="com.ptc.core.ui.navigationRB">

  <action name="customContent" type="custom"/>  <=== custom

  <action name="docStructureGWT" type="docsb" />

  <submodel name="docContentInfoDetails" />

  <submodel name="docRelatedObjectsInfo" />

  <submodel name="changesTab" />

  <submodel name="docObjectsHistoryTab" />

  <submodel name="requirementTraceabilityTab" />

  <action name="sysnavTab" type="sysnav" />

  </model>

and Make CustomTableBuilder.

did working good.... BUT

In, InfoPage .. contendTab did not working..

Not working <submodel name="docContentInfoDetails" /> ...

my custom edit page is just JSP page. no Wizard page...

add attachment actions is failed....
