redirect() in Composer throws NullPointer exception #342

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Which version of ZKGrails you're using? 
2.2.0

On what operating system?
Ubuntu 2013.04

Which version of Grails you're using?
2.2.1

What steps will reproduce the problem?
1. Create a Grails controller call Test, which simply renders some text in the 
index action using "render('Sample text');"
2. Create a Zk zul file.  Add a button to the zul.
3. Create a Zk Composer and tie it to the button on the zul. The button handler 
should try to redirect to the Grails Controller using 
"redirect(controller:'test');"
4. Run grails app and load zul page.
5. Click on zk button to redirect to Grails controller

What is the expected output? 
Should see output of Grials Test controller index action.

What do you see instead?
Exception stack print out.

Please provide any additional information below. Attaching a test case to
reproduce it is preferable.

redirect command is in the form of:

redirect(uri:"/path")

the controller and action parameters are not supported.
