CSLA Contrib - c# CodeSmith Templates

I am having some issues generating a source file when using a stored proc as my datasource vs. a view.  When I check my CodeSmith Schema Explorer (Oracle Database) I can navigate to my command, see my sproc and see the input / output variables (output is a refcursor).  The field in question is clearly defined as a varchar2(20).  The recursor is (select * from view) and generating from the view works okay.

Any ideas on where to look?

thx

Hi Jack, can you check to see if the column in question has an empty string in it?  If so, can you try updating to eliminate the empty strings?  This may be related to the Oracle Client having issues with empty strings on variable length columns.

That column can be null - I actually had engaged CodeSmith support with the issue and they found a bug or two in the Oracle schemaprovider.  The support person said they had a new build and would release it yesterday/today.  I haven't seen it yet but we'll see. 

I'll give that a try first and if that doens't cure the issue I'll try putting data in those columns - however that is only really going to help me to pass it along to CodeSmith as I can't obviously keep putting bogus data in the table just to run the CodeGen.  I also have a bunch of triggeres and RI on that table related to all the similar nullable string columns.

Thanks for you input and I'll update this when I get a update from CodeSmith
