Can any bode tell me whether it is Version incompatibility or any other specific reason ?

thanks

Hi Raja,

The problem is from the web dynpro side rather at the framework level. If you please can point me to the Travel Request Interactive Form document on the SDN, I can try that application and can have a discussion on the same.

Thanks and Regards,

Hi Krishna,

Thank you for the reply. Here is the URL

https://www.sdn.sap.com/sdn/developerareas/webdynpro.sdn?page=AdobeForms_Tips.htm

thanks

Hi Raja,

did you recognize the following part from the tutorial: "If you are running Web AS 6.40 (< SP8), there is a limitation that Adobe Forms cannot deal with a simple flat context structure as above. As a work around, you can create a dummy node (with cardinality 1..1) underneath the TravelData node with a dummy attribute. The context appears as shown below. This issue is fixed in SP8." Do you work with a version < SP8?

Hope that helps.

Regards

Hi Raja,

just to be sure, does your server and the Developer Studio have the same versions?

One possible reason for this kind of errors (NoSuchMethodExceptions related to Context) is, that you deploy with a NWDS having a version greater than the target WebAS server version.

Hope that helps.

Hi Raja,

something is wrong with your context in the component controller. Please verify your context structure with the structure in the document, which you mentioned. Do you really use value nodes and attributes? Is the mapping to the view correct and also the binding between the interactive form ui-element and the context nodes of the view?

Regards, Carsten
