I am using DevExpress to create an invoice. I have done this similar procedure several times now in SF (sales orders, acknowledgements, packing lists, etc.). Today I have been unable to resolve an error. Here it is:========== Message: Object does not match target type./r/nSource: mscorlib/r/nInner Exception: /r/nStack Trace: at System.Reflection.RuntimeMethodInfo.CheckConsistency(Object target)

When it reaches the very last field in the very last BO (extprice), the process aborts and displays the above error. I have been really struggling with this for two full days. Can anyone give me some pointers on this? I do not think it is the DevEx report...I think it has to do with the BO, BBS or Datasource somewhere along the line. Thanks,
Bill

I have worked around the error by replacing all calculated fields on the report with custom BO properties. For some reason, the report will not calculate simple things. Oh, well, it is better to have these kinds of things in the business object, anyway.Thanks,

Glad you got it going...we do not use XtraReports but rather Report Sharp-Shooter....we haven't had any issues on this side...however, we too generate custom properties many times...or, calculate this via the sproc or method that generates the results set depending on what we are trying to accomplish.

Yup...get it into the BO...experience is often a harsh, strict, but effective, teacher. Thanks.
