[teiid-issues] [JBoss JIRA] (TEIID-4829) odata4 fails to return data on top of mongoDB view model

[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-4829?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13385472#comment-13385472 ] 

Steven Hawkins commented on TEIID-4829:
---------------------------------------

That's showing a length of 0 for the affected columns.  Ideally it would trigger a metadata error in Designer, as that is not expected.

The runtime is effectively honoring that in the odata layer by indicating that the values are too long.  If you increase the length property to a wide enough value, the odata 4 path should work.

So the follow on tasks may be here:
- determine if a designer validation is needed
- determine what set the length to 0 initially.  How was the mongodb metadata created?
