Request map in template's context is being overwritten

    XMLWordPrintable

    Details

      Description

      After LPS-76631 the request map in the template's/ftl context is being overwritten with a javax.servlet.http.HttpServletRequest object, this makes to fail existing code in templates currently accessing to the request as a map.

      Steps to reproduce

      1. Add this code to a Web Content template, for example to the basic web content default template: 
        <#assign containerId = request["theme-display"]["portlet-display"]["instance-id"] >
instanceId: ${containerId}
      2. Add a basic web content.
      3. Add the created web content to a web content display in a page.

      Result: The instanceId is displayed.
      Expected: An error occurred while processing the template.

      And some details about the error, also the error is present in the log file:

      2018-02-05 11:41:15.600 ERROR [http-nio-8080-exec-4][runtime:60] Error executing FreeMarker template
FreeMarker template error:
The following has evaluated to null or missing:
==> request["theme-display"]  [in template "20100#20136#BASIC-WEB-CONTENT" at line 3, column 24]

----
Tip: It's the final [] step that caused this error, not those before it.
----
Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??

      SOLUTION

      In Master
      This fix introduces a BREAKING CHANGE, you can access to the request map using the "requestMap" object in context. So, this code should work:

      <#assign containerId = requestMap["theme-display"]["portlet-display"]["instance-id"] >
instanceId: ${containerId}

      And the "request" in template's context will have a javax.servlet.http.HttpServletRequest object.

      In 7.0.x
      The fix will recover the "request" object in context as a Map representation of the request. So, this code should work:

      <#assign containerId = request["theme-display"]["portlet-display"]["instance-id"] >
instanceId: ${containerId}

      Also, the javax.servlet.http.HttpServletRequest object will be present in the context and used with the name httpServletRequest.
