Well, unfortunately, rowId is one of three attributes that were not
implemented with best practices for supporting alternate view
handlers, and were implemented as generic attributes rather than
properties on the component itself.

    // dataTable (extended) attributes
    String ROW_ID                      = "org.apache.myfaces.dataTable.ROW_ID";
    String ROW_STYLECLASS_ATTR         =
"org.apache.myfaces.dataTable.ROW_STYLECLASS";
    String ROW_STYLE_ATTR              =
"org.apache.myfaces.dataTable.ROW_STYLE";

There's an old myfaces-dev thread dealing with this issue.

As a workaround, I think you can use
org.apache.myfaces.dataTable.ROW_ID="#{index}" to assign the value.

Another workaround is to implement a Facelets component handler that
aliases  rowId to org.apache.myfaces.dataTable.ROW_ID.  See this url: 
https://facelets.dev.java.net/nonav/docs/dev/docbook.html#dev-meta-component

You should probably open an JIRA issue on this so we remember to fix
this directly on t:dataTable.

There's a similar issue open for Tree2 which you could use as a
guideline for creating a patch if you were so inclined.
