An Entity With Key (pk) Will Not Round-trip When
I have this error when I build my Web Service: Error 3004: Problem in mapping fragment starting at line 323: No mapping specified for properties JE_TRN_HS.JE_HDR_HSJE_HDR_KEY. Entity is type [TESTCPModel.JE_TRN_HS This is what happend. I created this Entity Data Model from an existing database. I added 2 tables and rebuilt the Web Service. The build was successfull. THEN I added an Association between the two tables. When I tried to rebuild
Entity Type Is Not Mapped
it failed with the error message displayed above! Now here's the kicker! I deleted the newly added Association and rebuilt. The build failed with the same error message!? The only way I can get rid of this error is if I delete the second table, rebuild and re-add the second table?? I've looked EVERYWHERE for the solution to this problem!

By default it uses independent assoc
