Kennard Consulting updated JEXL-138:
------------------------------------
Description:
JEXL displays an erroneous "inaccessible or unknown property" warning when you
try to access a property is both accessible, and known, but that happens to
return null.
Please see the attached test case. JEXL reports:
{{'foo.bar;' inaccessible or unknown property foo}}
But foo is clearly an accessible and known property because it is accessed
directly 2 lines above, and 1 line above we access 'foo.baz' which works
without error.
The difference seems to be that getBaz() returns "baz" whereas getBar() returns
null.
was:
JEXL displays an erroneous "inaccessible or unknown property" warning when you
try to access a property is both accessible, and known, but that happens to
return null.
Consider the following code:
---
public void testInaccessibleProperty()
throws Exception {
JexlEngine engine = new JexlEngine();
JexlContext context = new MapContext();
context.set( "foo", new Foo() );
// These lines okay
System.out.println( engine.createExpression( "foo" ).evaluate(
context ));
System.out.println( engine.createExpression( "foo.baz"
).evaluate( context ));
// This line says:
// org.apache.commons.jexl2.Interpreter unknownVariable
// WARNING:
org.metawidget.example.swing.appframework.JexlTest.testInaccessibleProperty@44![0,7]:
'foo.bar;' inaccessible or unknown property foo
System.out.println( engine.createExpression( "foo.bar"
).evaluate( context ));
}
public class Foo {
public String getBar() {
return null;
}
public String getBaz() {
return "baz";
}
}
