How to pass java obj between Workflow and Form

hi I created a java obj using <new class='com.foo.classname'/> in Action id='0'

then I have a manual action. After the manual action exits, the java obj is null? see postPrintVars action.....

Bottomline: I need to pass a reference to java obj, back and forth between workflow and form.

Here is my code.............

******************************************************************************* ***

<Action id='2' name='SetArnObj'>

<expression>

<block trace='true'>

<set name='global.arnObj'>

<new class='com.foo.idm.util.beans.AccessRequest'/>

</set>

</block>

</expression>

</Action>

<Transition to='DataForm'/>

<WorkflowEditor x='142' y='247'/>

</Activity>

<Activity id='1' name='DataForm'>

<ManualAction id='1' name='ActivationForm' timeout='20' syncExec='true' itemType='Activation'>

<ReportTitle>

<s>ActivationForm</s>

</ReportTitle>

<Owner>

<ref>WF_CASE_OWNER</ref>

</Owner>

<FormRef>

<ObjectRef type='UserForm' name='VGA1-UserForm-TestOnly'/>

</FormRef>

<ExposedVariables>

<List>

<String>global.arnObj</String>

</List>

</ExposedVariables>

</ManualAction>

<Action id='2' name='postPrintARNObj'>

<expression>

<ref>global.arnObj</ref>

</expression>

</Action>
