[teiid-issues] [JBoss JIRA] (TEIID-2094) Projecting node issue

[Steven Hawkins (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-2094?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins updated TEIID-2094:
----------------------------------

    Description: 
If a non-pushed source node (inline view) is located over a projecting node (windowfunctionproject, join, group, or a select node) the resulting construction of the projection/projection indexes will be incorrect or fail - as the input elements will not match the output elements that have been set to the views elements.

Note that not all nodes should be the first child under a source.  For example, join/group should not appear there (typically it will be one of project/windowfunctionproject/limit/sort/unionall/select).  Other child nodes besides windowfunctionproject/select could have issues, since we are not specifically coding to use a different set of output vs. original elements such as with ProjectNode that holds elements and selectSymbols respectively.
