Here is an overview of the issue:
---------------------------------------------------------------------
Key: JELLY-88
Summary: Jexl Expressions don't obey scope inheritance
Type: Bug
Status: Unassigned
Priority: Major
Time Spent: Unknown
Remaining: 5 minutes
Project: jelly
Components:
core / taglib.core
Assignee:
Reporter: Scott Howlett
Created: Tue, 30 Sep 2003 11:36 AM
Updated: Tue, 30 Sep 2003 11:36 AM
Description:
A JexlExpression gets variables via the following JellyMap method:
public Object get(Object key) {
return context.findVariable( (String) key );
}
findVariable() locates requested variable in any enclosing scope regardless of inheritance. This is an error - getVariable() ought to be used instead.
The problem can be seen in the following example:
Given these scripts:
foo.jelly:
<?xml version="1.0"?>
<j:jelly xmlns:j="jelly:core">
<j:set var="test" value="goofy"/>
<j:import inherit="false" uri="bar.jelly"/>
</j:jelly>
bar.jelly:
<j:jelly xmlns:j="jelly:core">
${test}
</j:jelly>
When I execute foo.jelly, the expression in bar.jelly finds the value of test even though inheritance is false.
I looked through the CVS history for JexlExpression.java - it looks like the statement in question was inadvertently changed from getVariable() to findVariable() between revisions 8 and 9 (the change is not described in the revision 9 checkin comment).
