Exception caught: (TypeError) _17 is undefined

[basis.marcio]

Hello, guys.

I'm getting this weird uncaught exception (client-side) when trying to save a form which contains an UploadItem field. If I remove the field, everything works just fine.

I attached the DataSource as it gets to the client and the exception full stack trace.

I've been working on this issue for a couple days now and couldn't figure out what the root cause might be. Any ideas of what could cause this to happen?

Thanks in advance.

We tested it again with SmartClient Version: v8.3p_2013-11-16 and the exception still occurs.

Any ideas of what might cause this?

Unfortunately this stack trace isn't giving us enough to determine what's going on.
The best way to proceed would be for you to show us a way to reproduce the problem. We'd recommend you create a small standalone test case we can actually run along with steps to reproduce the issue.
The best way to build such a test case is usually one of the following:
- Either create a new EntryPoint module consisting of a greatly simplified version of your existing app which contains only the DataSource definitions and the components which actually are involved in the failure. You can then typically remove any dependencies, and often replace the dataSources with ClientOnly dataSources so we have a self contained file or two which we can run.
- Or - use one of the existing samples, either a showcase example or one of the simple standalone projects like built-in-ds, as a basic scaffolding, and modify the components / DataSources to have similar properties to those in your app such that the problem manifests there.
