Parser generates a NullPointerException for invalid use case of jsp:attribute instead of a useful message.
Summary: Parser generates a NullPointerException for invalid use
case of jsp:attribute instead of a useful message.
Product: Tomcat 5
Version: Nightly Build
Platform: All
OS/Version: All
Status: NEW
Severity: Normal
Priority: Other
Component: Jasper2
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: Ryan.Lubke@Sun.COM
Consider the following fragment which is supposed to generate a translation-time
error:
<jsp:attribute>
<jsp:attribute name="name">
someattr
</jsp:attribute>
<jsp:body>
someattrvalue
</jsp:body>
</jsp:attribute>
According to the specification, if a jsp:attribute standard action is nested
within another jsp:attribute standard action, a translation error must occur.
In this case, a translation error does occur, but for the wrong reason. Here is
the resulting cause:
