[jira] Commented: (WW-3040) Context supplied through convertValue to custom converter is missing many key-value pairs (including ServletContext)

["David Mansfield (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/struts/browse/WW-3040?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=46297#action_46297 ] 

David Mansfield commented on WW-3040:
-------------------------------------

the valuestack present during type conversions that take place during the parametersinterceptor is a "fake" stack created to prevent some security problems.  the fake stack doesn't contain almost any of the things the real stack has, including what you need.  

i'm not sure there's a way to get what you're looking for, but for reference, here's a previous report similar to yours:

> I recently upgraded from Struts 2.0.11 to 2.1.6. I had a custom date converter class. In the convertValue method, I had the code:
> ServletContext servletContext = (ServletContext) context.get(StrutsStatics.SERVLET_CONTEXT);
> I was getting the servletContext and I was reading a param where I had my date pattern. 
> With 2.0.11, the above code returns the servletContext. With 2.1.6, I get null. Basically, the difference in the context provided through 
> public Object convertValue(Map context, Object value, Class toType) {}
> is this:
