Summary: Escaping EL doesn't work in Tomcat 6
Product: Tomcat 6
Version: 6.0.7
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Jasper
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: arjan.tijms@mbuyu.nl
We're using a number of custom tags that accept JSF (deferred) EL through
dynamic attributes. In JSP 2.1 this is illegal. I therefore tried to deactivate
expression evaluation by escaping the #{ pattern, but it seems that Tomcat 6.0.7
ignores this?
E.g.
<x:myTag id="someID" someDynamicAttribute="\#{someBean.someProp} />
Where myTag would be declared like this:
<tag>
<description>...</description>
<name>myTag</name>
<tag-class>com.someClass</tag-class>
<body-content>empty</body-content>
<attribute>
<description>...</description>
<name>id</name>
<required>false</required>
<rtexprvalue>false</rtexprvalue>
</attribute>
<dynamic-attributes>true</dynamic-attributes>
</tag>
This results in a:
org.apache.jasper.JasperException: Unable to compile class for JSP
where the deepest nested stack trace starts with:
java.lang.NullPointerException

at org.apache.jasper.compiler.Node$CustomTag.accept(Node.java:1507)
at org.apache.jasper.compiler.Node$Nodes.visit(Node.java:2336)
In a simple outputText escaping is ignored too.
Something like:
<h:outputText value="\#{someBean.someProp}" />
would render a literal "\" before the value of "someProp".
Escaping EL is mentioned here:
http://java.sun.com/javaee/5/docs/tutorial/doc/JSPIntro7.html
e.g.
"Escape the #{ or ${characters as follows:
|some text \#{ some more\${ text
| and
|<my:tag someAttribute="sometext\#{more\${text" />"
|
