Description Satyaranjan D 2008-07-23 09:38:56 UTC 
The IDE is not able to resolve the implicit variables defined by the custom taglib in a jsp page. The jar containing tld
and taglib implementation is already there in the web application's classpath. I can see the code completion for the jsp
tags but the IDE shows the error for the implicit variables defined in the TagExtraInfo class of those tags.

Please refer to the attached sample application.
Steps to reproduce:
- Open the attached NetBeans project
- Open WEB-INF/jsp/HelloWorld_view.jsp
- You can find "renderResponse" variable is shown as unresolved even though this variable is defined in the
DefineObjectsTagExtraInfo taglib class.
- But the other taglib code completion help for all <portlet:* tags are coming fine.

Let me know if you need any other info.

Comment 2 Marek Fukala 2008-07-25 17:50:35 UTC 
reproducible. Likely JSP parser doesn't provide such information or virtual java source just doesn't reflect it.
Reassigning to Tomasz for evaluation.
Comment 3 Satyaranjan D 2008-08-29 08:04:38 UTC 
Are we going to fix it for NB 6.5 ?
Comment 4 Satyaranjan D 2008-08-29 08:10:02 UTC 
It's a usability issue. Many users post messages about this issue. It has been there since NB 6.1 . So changing the
priority to P2.
Comment 5 Tomasz Slota 2008-09-01 14:59:28 UTC 
I filed issue 145813 about the missing data from JspParser.

Here is a draft of the solution that will be implemented in the SimplifiedJSPServlet class:

JspSyntaxSupport syntaxSupport = JspSyntaxSupport.get(doc);
        Collection<String> prefixes = JspUtils.getJSPColoringData(doc, fobj).getPrefixMapper().keySet();

        for (String prefix : prefixes) {
            List<TagInfo> tags = syntaxSupport.getAllTags(prefix);

            for (TagInfo tag : tags) {
                for (TagVariableInfo var : tag.getTagVariableInfos()) {
                    // Create Variable Definitions
                }
            }
        }
