Embed OVP in custom Web Dynpro

Question

Hi,
I'm experiencing a similar problem as described [here|How to Embed FPM ABAP into a WebDynpro ABAP Application;, but that thread is closed (unanswered).
I want to embed an (ESS) OVP component in my Z Web Dynpro. I defined a component usage for the OVP component, embedded its window in a view container. I also set the configuration 'XYZ' for the OVS component:
   1. using code (as in FPM developer's guide)
   2. by means of an application configuration for my Z Web Dynpro
Both approaches to set the configuration (1 and 2) yield into the same result at runtime: see B
A) When I run the OVP component directly (OVP app with config XYZ), it works (ESS data is shown in FPM_LIST_UIBB panes).
B) When I run my Z Web Dynpro, only the header of the OVP component is shown (no FPM_LIST_UIBB panes with data).
Following symptoms make me think my Z Web Dynpro set up is correct and it is a FPM/Web Dynpro bug:
   1. Something of OVP component is shown (page header), so it is initialized and runs
   2. When I open my app while my PERNR is locked, the OVP component shows it in a message (exactly as in case A): "Person is already being processed by user XYZ123")
Did I forget something? Do you think it could be a bug?

Hi Joachim,
To embedd object selector in your custom UI you can use two interfaces which are implemented by this component. There are ObjectSelectorCI and CommandletCI.
I recommend you to use the ObjectSelectorCI. There are no methods in this interface. So, you need to add this interface to used components from cafuiptn~common dc, the "CommonInterfaces" public part. The only configuration step which you need to perfrom is create component and setup object selector configuration name to context
like this:
     String componentName = "com.sap.caf.ui.ptn.objectselector.ObjectSelector" ;
     String devComponentName = "sap.com/caf~UI~ptn~objectselector" ;
     IWDComponentUsage usage = wdThis.wdGetObjectSelectorComponentUsage();
          WDUtils.createComponent(usage, componentName, devComponentName, true) ;
IExternalObjectSelectorCI interface =
wdThis.wdGetObjectSelectorInterface()
IWDNodeElement selectorConfig = interface.wdGetAPI().getContext().getRootNode().getCurrentElement();
selectorConfig.setAttributeValue("configName", configName);
And that's it. Actually, I never done it, if you'll get a problem please let me know.
Best regards,
