ABAP WebDynpro work item in uwl doesn't work

Hi,

an ABAP WebDynpro by itself works. But using it in a uwl work item doesn't work:

After clicking the button to start the WebDynpro in a uwl work item a browser opens but the site could not be load.

So something is wrong with the url:

http://<host>:<port>/irj/servlet/prt/portal/prteventname/Navigate/prtroot/pcd!3aportal_content!2fevery_user!2fgeneral!2fdefaultDesktop!2fframeworkPages!2fframeworkpage!2fcom.sap.portal.innerpage!2fcom.sap.portal.contentarea?NavigationTarget=ROLES%3A%2F%2Fportal_content%2Fevery_user%2Fgeneral%2Fuwl%2Fcom.sap.netweaver.bc.uwl.uwlLaunchWebdynproABAP&System=T70CLNT100&WebDynproNamespace=sap&WebDynproApplication=zwps_bspobj_Ship_set&DynamicParameter=wi_id%3D000000004020%26WI_ID%3D000000004020&CurrentWindowId=WID1181552609217&NavMode=1

This is the uwl configuration part:

[code]

<ItemType name="uwl.task.webflow.TS97300003.T70CLNT100" connector="WebFlowConnector"

defaultView="DefaultView" defaultAction="launchWebDynPro" executionMode="default">

<ItemTypeCriteria systemId="T70CLNT100" externalType="TS97300003" connector="WebFlowConnector"/>

<Actions>

<Action name="launchWebDynPro" groupAction="" handler="SAPWebDynproABAPLauncher"

returnToDetailViewAllowed="yes" launchInNewWindow="yes"

launchNewWindowFeatures="resizable=yes,scrollbars=yes,status=yes,toolbar=yes,

menubar=yes,location=yes,directories=yes">

<Properties>

<Property name="WebDynproApplication" value="zwps_bspobj_Ship_set"/>

<Property name="newWindowFeatures" value="resizable=yes,scrollbars=yes,status=yes,

toolbar=yes,menubar=yes,location=yes,directories=yes"/>

<Property name="DynamicParameter" value="WI_ID=${item.externalId}"/>

<Property name="openInNewWindow" value="yes"/>

<Property name="WebDynproNamespace" value="sap"/>

<Property name="display_order_priority" value="5"/>

</Properties>

<Descriptions default=""/>

</Action>

</Actions>

</ItemType>[/code]

What's wrong? Any idea?

Thanks,

Susanne
