Telerik Open Access error on string with 8000 characters

Question

I'm trying to save 8,000 characters to a SQL Server Express database table, and this may be smaller or larger in the future, and I'm getting an exception saying that the data will be truncated.

I've already set the column to varchar(max) and don't know if there is another setting for the ORM itself.

Any help is appreciated

Is there anywhere from within the visual designer where you can see what the column is set to? Data-type that is? — KreepN, Dec 03 '13 at 03:32
Are you setting any other columns to anything during this update? It looks like it?: "[PI]=?, [ReqState]=?, [second_message_date]=?, [second_message_j_s_o_n]=?, [TI]=?". Perhaps one of those is not the required length in the db to support the inserted value. — KreepN, Dec 03 '13 at 04:52
@kreepn yes the problem is with the column reqstate. If I don't set the value than everything is fine. I inspected the coin and that is the column with 8000 chars. I right clicked on the designer and made sure the column was varchar max. I also deleted and recreated the table. — makerofthings7, Dec 03 '13 at 12:56
The next step would I guess be to check the value of said column and verify it really is only 8000: http://documentation.telerik.com/openaccess-orm/developers-guide/tracing-and-logging/openaccess-tasks-tracing-and-logging-enable-log . Turn that on and you should be able to grab the value, copy it out, and paste into a text editor to check the length. — KreepN, Dec 03 '13 at 15:16

@makerofthings7, my best guess about the re-appearance of the error after the fix is that the model and the database are not in synchronous. It seems that you have modified the table in the storage model in Visual Designer and in order to complete the fix, I would suggest to you to run the Update Database From Model wizard and to transfer the change in the database.

I hope this helps.
