[20040503] To reproduce: 1) create a webproject (WP) 2) create a JSP page 3) run the project 4) from files view expand build/web node 5) try to open the -deployed- JSP => java.lang.IllegalArgumentException: MasterFileObject@17e18d5[file:/E:/testing/projects/p1/web/] / MasterFileObject@8aa4b[file:/E:/testing/projects/p1/build/web/test.tag] The some happens for tag library descriptors, HTMLs (and probably other webmodule specific objects). Note that for example text files can be opened without problems.

this is caused by jsp parser not being able to find a web module corresponding to the jsp. in org.netbeans.modules.web.core.jsploader.JspParserAccess it says: // PENDING - will also need this: //public static JspParserAPI.WebModule getParserWMOutsideWM (FileObject packageRoot) { } which is probably what is needed.
actually I found I cannot reproduce the problem doing the steps that you listed bellow....
