[4.1.10-dev] Jasper 2 problems

[Remy Maucherat <re...@apache.org>]

Hi,

I'm testing 4.1.10-dev before tagging, and I ran into some serious problems.

Jasper 2 seems broken (in the TC 4 branch; the HEAD/TC 5 branch may be 
broken as well, but I didn't have time to test it), and fails to compile 
most pages from the admin webapp.

There seems to be a problem with the nested variable declaration code.

I attach the errors I get with the mail sessions page.

The generated code looks like (for the "hostInfo" variable):

                   /* ----  bean:define ---- */
                   {
                     java.lang.String hostInfo = null;
                     org.apache.struts.taglib.bean.DefineTag 
_jspx_th_bean_define_2 = (org.apache.struts.taglib.bean.DefineTag) 
_jspx_tagPool_bean_define_type_property_name_id.get(org.apache.struts.taglib.bean.DefineTag.class);
                     _jspx_th_bean_define_2.setPageContext(pageContext);
                     _jspx_th_bean_define_2.setParent(_jspx_th_html_form_0);
                     _jspx_th_bean_define_2.setId("hostInfo");
                     _jspx_th_bean_define_2.setType("java.lang.String");
                     _jspx_th_bean_define_2.setName("mailSessionsForm");
                     _jspx_th_bean_define_2.setProperty("host");
                     int _jspx_eval_bean_define_2 = 
_jspx_th_bean_define_2.doStartTag();
                     if (_jspx_th_bean_define_2.doEndTag() == 
javax.servlet.jsp.tagext.Tag.SKIP_PAGE)
                       return;
                     hostInfo = (java.lang.String) 
pageContext.findAttribute("hostInfo");
 
_jspx_tagPool_bean_define_type_property_name_id.reuse(_jspx_th_bean_define_2);
                   }

<snip/>

                         /* ----  controls:action ---- */
                         {
                           org.apache.webapp.admin.ActionTag 
_jspx_th_controls_action_2 = (org.apache.webapp.admin.ActionTag) 
_jspx_tagPool_controls_action_url.get(org.apache.webapp.admin.ActionTag.class);
 
_jspx_th_controls_action_2.setPageContext(pageContext);
 
_jspx_th_controls_action_2.setParent(_jspx_th_controls_actions_0);
                           _jspx_th_controls_action_2.setUrl( 
"/resources/setUpMailSession.do?resourcetype=" +
                             URLEncoder.encode(resourcetypeInfo) + "&path="+
                             URLEncoder.encode(pathInfo) + "&host="+
                             URLEncoder.encode(hostInfo) + "&service="+
                             URLEncoder.encode(serviceInfo) );
                           int _jspx_eval_controls_action_2 = 
_jspx_th_controls_action_2.doStartTag();

I assume "hostInfo" shouldn't be nested in the block when it is declared 
(or the block should be much bigger).
