[jira] [Comment Edited] (WW-4572) Add dedicated class to represent Http Parameters

["Glen Mazza (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WW-4572?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15642519#comment-15642519 ]

----------------------------------------------------------

This change appears to break backwards compatibility, upon upgrade from Struts 2.5.2 to 2.5.5 the following code no longer worked:

{
    <s:property value='%{#parameters.weblogId}'/>   // returns empty string.
}

Apparent solution (haven't tested yet) is here: http://stackoverflow.com/a/40365187/1207540

> Right now {{parameters}} are represented by a {{Map}} and a lot of logic is duplicated. There is no way to check if given parameter was already evaluated.
