RE: Struts tags with Groovy meta programming
ask this question on tomcat-users list
Groovy and all CGI languages do not exist in J2EE world (correction i havent
seen any Groovy parsers implemented in TC,GF or WL or JBoss)
Groovy Rails as GRAILS with Spring Framework is available at
http://grails.org

Re: Struts tags with Groovy meta programming
yes, field/methods are calling using reflection, I have no idea how
the Groovy MetaClass works. You can look at the OGNLReflectionProvider
class, that's the one doing the reflection stuff.

Re: Struts tags with Groovy meta programming
Anyone?
Does the struts tags do some reflection magic that bypass the Groovy
MetaClass?

I was expecting "Baz is: new value", which is true for this test:
class FooActionTest extends GroovyTestCase {

FooAction action = new FooAction()
action.retrieveBar()
assertEquals "new value", action.bar.baz
}
}
Any idea on how I from a Struts tag can invoke the overridden getBaz
method instead of the original one?

Struts tags with Groovy meta programming
How can I from a Struts tag access properties that is overridden by
Groovy meta programming?
Example:
Bar.groovy
---
class Bar {
String baz
}
FooAction.groovy
-
class FooAction extends ActionSupport {
Bar bar
String retrieveBar() {
bar = new Bar(baz: "original value")
bar.metaClass.getBaz = {"new value"}
return SUCCESS
}
}
foo.jsp
<%@ taglib prefix="s" uri="/struts-tags" %>
Baz is:
Which yields the output "Baz is: original value"
I was expecting "Baz is: new value", which is true for this test:
class FooActionTest extends GroovyTestCase {
void testRetrieveBar() {
FooAction action = new FooAction()
action.retrieveBar()
assertEquals "new value", action.bar.baz
}
}
Any idea on how I from a Struts tag can invoke the overridden getBaz
method instead of the original one?
