Issue with Grails WebFlow and AJAX

[Brian Riley]

Hi,

I'm trying to get a test webflow working via AJAX calls and I am stuck. I'm not sure what I'm missing. It seems like it doesn't understand the path to the template because the <tr id="attributeEdit"> gets blanked out after the webflow renders.

My view, /application/workcard.gsp, has a table with one row being generated via the template below:

/attribute/_edit.gsp

<tr id="attributeEdit">
<td><label title="attributes">ATTR</label></td>
<td colspan="3">
	<div>
		<g:if test="${ msg }">
			${ msg }
			
			<g:remoteLink update="attributeEdit" 
						  controller="attribute" 
						  action="ajaxAttributeChanges" 
						  event="cancel" 
						  params="${ [ajaxSource: true, execution: params.execution] }">cancel</g:remoteLink>
		</g:if>
		<g:else>
			<g:remoteLink update="attributeEdit" 
						  controller="attribute" 
						  action="ajaxAttributeChanges" 
						  event="edit" 
						  params="${ [ajaxSource: true] }">edit</g:remoteLink>
		</g:else>
	</div>
</td>
</tr>

AttributeController.groovy

class AttributeController {

	def ajaxAttributeChangesFlow = { 
		
		edit {
			action{
				flow.msg = "We made it through the edit state"
			}
			on("success").to("display")
		}
		
		display {
			render( template: "/attribute/edit", model: [msg: flow.msg] )
			
			on("cancel").to("cancel")
		}
		
		cancel()
        }
}

I tried /attribute/_edit, edit, _edit with both template and view but they all have the same behavior.

I turned the debug on in my config for org.codehaus.groovy.grails.webflow but all I get is this:

2011-10-20 20:57:17,247 [http-8080-1] DEBUG servlet.GrailsFlowHandlerMapping  - Looking up Grails controller for URI [/application/workcard]

I found the 'ajaxSource: true, execution: params.execution' stuff on CloudFoundry.

What am I missing? It has to be something simple. Any help or advice is appreciated.

Ok, answered my own question. The render statement needed to be in the edit state. There was no need for the display state
