Subject [jira] [Created] (WW-4813) NP with TextProvider and wildcardmapping
Date Wed, 12 Jul 2017 15:59:00 GMT
Markus Fischer created WW-4813:
----------------------------------

             Summary: NP with TextProvider and wildcardmapping
                 Key: WW-4813
                 URL: https://issues.apache.org/jira/browse/WW-4813
             Project: Struts 2
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.5.12
         Environment: Linux / FF / Java 8
            Reporter: Markus Fischer
             Fix For: 2.5.x


Probably another corner case around TextProvider in connection with wildcard mapping:

Embeded elements (in URLs, image tags...) in jsp like {{<s:text name="edit"/>}} throw
an NP-Exception.

{{struts.xml}}
{code}
        <action name="**" class="org.package.MyClassDoingNothing">
          <result name="test">/view/test.jsp</result>
        </action>
{code}

{{test.jsp}} contains an element like this:
{code}
<img title="<s:text name="edit"/>" alt="<s:text name="edit"/>" src="deleteImage.jpg"/>
{code}

This will give since 2.5.12 null pointer exception:

{code}
