[teiid-issues] [JBoss JIRA] Commented: (TEIID-1503) Exception during Optimization

[Ramesh Reddy (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-1503?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12586702#comment-12586702 ] 

Ramesh Reddy commented on TEIID-1503:
-------------------------------------

The convert is also required in the form {fn convert (...)}, so when I register that it was rewriting the cast as convert. Now I am just going to add to supported functions. Attached is the vdb.
