Classcast Exception in AdaptiveWS model

[Former Member]

Hello All,

We have made few attribute addition in the existing structure.

After reimporting the WS model, we are getting the below error message,

java.lang.ClassCastException: class com.XXXX.XXX.mdm.massupload.wd.models.sbmvalidatewsmodel.String_Item:nokia.com/sbm~mdm~massupload@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@d385362@alive incompatible with class com.XXXX.XXX.mdm.massupload.wd.models.sbmvalidatewsmodel.ErrorMessage:nokia.com/sbm~mdm~massupload@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@d385362@alive

The Web Service is returning the list and when we try to initiate the element it throws the above error.

wdContext.nodeValidationErrors().nodeErrorMessage_2().getErrorMessage_2ElementAt(m).getItem1();

Could you please help what could be the reason and how to fix?

Thanks in advance.

Regards,

Senthil

Senthil,

Try to delete the project from Web Dynpro perspective. Close NWDS and delete .metadata folder. 

location of metadata folder : C:\Documents and Settings\<USER ID>\Documents\SAP\workspace

Again create a project from NWDI.

Hope this helps!!

Thanks & Regards
