UWL SWFVISU WebDynpro - application as paramater

[Dart, Jocelyn]

Hi Robert
Please look again at my suggested alternative if you can't get your preferred option working (but by all means try that first - it looks plausible).

You really do *not* want to call the wda or iview in a method. We have seen a number of sites try this and it leads to all sorts of unfortunate side effects particularly around web browser sessions.

Task expressions are very easy to use and a great technique to add to your collection

Jocelyn, all,


I have a container element with the correct webdynpro application (and/or URL).

I also have a containerelement with a parameter for the caseID for which the task is concerned.



So I want to call the WebDynproLaucher with the correct application and also pass the parameter so the data from the backend can be retrieved within the WebDynpro application.



I thought maybe it is possible to change the UWL XML so the value for the WebDynproLaucher is a variable?



For example (with CONTAINER_ELEMENT_URL and caseID):


<ItemType name="uwl.task.webflow.TS99900078" connector="WebFlowConnector"

defaultView="DefaultView" defaultAction="launchWebDynPro"

executionMode="default">

  <ItemTypeCriteria externalType="TS99900078" connector="WebFlowConnector"/>

  <Actions>

     <Action name="launchWebDynPro" handler="SAPWebDynproLauncher">

       <Properties>

       <Property name="WebDynproApplication" value="${item.CONTAINER_ELEMENT_URL}"/>

       <Property name="WebDynproDeployableObject" value="sap.com/tc~wd~tools<http://sap.com/tc~wd~tools>"/>

       <Property name="System" value="SAP_LocalSystem"/>

       <Property name="caseID" value="${item.caseID}" />

       </Properties>

    </Action>

</Actions>

</ItemType>





Other possibilities:

- call the WebDynpro from the method in de task. So then the XML in the UWL must be a tasklauncher in the back-end. But how can I call a WebDynpro from ABAP (with a parameter)?

- or call the iView URL direct from the backend. So then the task in the UWL must be a tasklauncher in the back-end. But how can I call a URL from the UWL via a workflow task/method?

Robert

Hi Robert,

You can pass whatever parameters you need to DYNPARAM but that’s usually
for the parameters passed to the application itself.

The difficulty might be in getting the UWL to launch the correct
application, but its theoretically possible. An alternative is to pass
it as a container element of the task.

Remember SWFVISU is only used to generate the UWL XML file entry – you
can always override it in your custom UWL XML file.



Give it a go but I don’t promise anything.



Just thinking an alternative may to be to use a Task Expression to solve
the problem – i.e. have a task for each application but use the Task
Expression field on the workflow step to default in the correct task for
the correct application using a workflow container element. Then your
SWFVISU would still have 7 different tasks, but your workflow would only
have one task at design time.

Just a thought… as that’s how I would approach it personally… i.e. work
with the existing functionality rather than counter to it.

Up to you though…..

Regards,

Jocelyn

Subject: SWFVISU WebDynpro - application as paramater



All,



We have an application where we have 1 workflow task in de UWL which we
want to be used for 7 WebDynpro applications. In the workflow, I can
determine the correct webdynpro application.



Is it possible to pass the application as a paramater? So the setting
"APPLICATION" inSWFVISU with the type WebDynpro ABAP?



Or should I use an iView and let the method call the URL? And if that is
the solution: how can I pass a parameter to the iView? Using DYNPARAM?



Kind regards,

Robert
