-------------------------------------
Yes, I verify the error message is the same in 8.1.0.CR1. I can tell by the stacktrace the
message is generated by the Jasper compiler -- which is not a JBoss component. If you want
to open up a corresponding ticket in Tomcat (owners of jasper?), that would be ideal.
Confusing error message when tag file's attribute type is
unknown
-----------------------------------------------------------------
Key: WFLY-3267
URL:
https://issues.jboss.org/browse/WFLY-3267
Project: WildFly
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: Web (Undertow)
Affects Versions: 8.0.0.Final
Reporter: Paul Benedict
Assignee: Remy Maucherat
Priority: Trivial
I have a JSP tag file that requires a "size" attribute:
{code}
<%@ attribute name="size" required="true" type="Long"
%>
{code}
Because the type accidentally wasn't a FQN (it should have been a
{{java.lang.Long}}), this error was generated:
{code}
JBWEB004193: Unknown attribute type (size) for attribute Number
{code}
The message doesn't make any sense. "size" isn't the attribute type and
the attribute is not "Number". A possible fix:
{code}
JBWEB004193: Unknown type (Number) was declared for attribute (size)
{code}
PS: It's really important to talk about the "declaration" here because the
tag file isn't mentioned at all in the exception. The Jasper compiler only reports the
enclosing JSP, which makes it look like the problem is with the usage not the tag file
itself.
