Subject [jira] [Commented] (MYFACES-3981) Unable to resolve Integer API as Lambda expression in a facelet
Date Mon, 05 Oct 2015 20:42:26 GMT

    [ https://issues.apache.org/jira/browse/MYFACES-3981?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14943985#comment-14943985
] 

Thomas Andraschko commented on MYFACES-3981:
--------------------------------------------

Yep thats true - same as: https://issues.apache.org/jira/browse/MYFACES-4008

We could of course use reflection but thats not a good way IMO.
We should update the servlet 3.1 (for ticket 4008) and EL 3 and do something like:
if (el3Available) {ImportHandler....}

This should also work fine for el 2.2 as the code is only executed with EL 3.0.
We use some of such statements in PrimeFaces and this is working fine.

[~lu4242] WDYT?
