Exception:com.sap.tc.webdynpro.progmodel.context.ContextException: NodeElem

74 Views

Hi Experts,

I am consuming RFC to my webdynpro java application. The rfc takes some input values and returns some output vaules.

In the application I had taken model to my component and mapped ( model --> component --> view ). i created Application and deployed it. it is giving the following Exception.

com.sap.tc.webdynpro.progmodel.context.ContextException: NodeElement(.ComponentOne.Zbapi_Material_Create_Input): model node element cannot be created without a model instance

at com.sap.tc.webdynpro.progmodel.context.ModelNodeElement.<init>(ModelNodeElement.java:63)

at com.sap.demo.sample.wd.comp.componentone.wdp.IPublicComponentOne$IZbapi_Material_Create_InputElement.<init>(IPublicComponentOne.java:357)

at com.sap.demo.sample.wd.comp.componentone.wdp.IPublicComponentOne$IContextNode.doCreateElement(IPublicComponentOne.java:55)

at com.sap.tc.webdynpro.progmodel.context.NodeInfo.createElement(NodeInfo.java:1269)

Here actually it had to display the input screen (default view page )but while loading the starting page it gives the above exception.

I searches lot of forums, but they are related to particular inputfields, but here it is not that scenario, i am not using any fields here just to display the view page. I don't know exactly what was the mistake, Help me please if you know.

Regards,

Pradeep Kumar
