Error while creating query

[Former Member]

Hi ,

I am creating 7.1 laptop application, I am getting error while creating the queries. I have 2 queries in my Model DC, When I create the 1st query I am able to use it in the applicationDC without any problem, But when I am creating the second query, I am getting exception "Caused by: com.sap.tc.mobile.exception.standard.SAPIllegalArgumentException: Cannot find class com.acc.iss.issdatamodel.GetAccountDetails" . At design time in the application, I dont face any problem and I am able to build the application also. But during runtime at applicaiton la the error starts coming. In my 2nd query I have an input attribute and output based out on this input attribute.

The detailled error trace is below

Hi Priya,

I also have this error. In fact every time I do a change in my model DC, it is not reflected in my other DC which depends on this one. Rebuild, reload, .. nothing helps...

Did you eventually found the problem? Reinstalling the client solves the problem, but as you can imagine, that's not a helpful trick.

Dear SDN'ers,

I reported this error to SAP. A bugfix will be foreseen for this in the following patch for MI7.1 SP9, probably patch3.

regards

Peter
