I am having a problem getting resources (javascript, etc) to resolve in a page with PrimeFaces component and SWF. The page displays, but is not including the PrimeFaces resources. Thoughts?

I am currently using PrimeFaces-2,1.RC1.jar with MyFaces 2.0.0 and Spring WebFlow 2.2.0M1.

I configured Spring Web Flow as per the blog entry http://blog.springsource.com/2010/08/05 ... -released/

I am looking to simply display the following page via SWF:

Code: Select all

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 	"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

         xmlns:p="http://primefaces.prime.com.tr/ui">

<head>
 <title>test</title>
</head>
<body>
 <h:form>  
   	<p>This is a step in flow</p>
	<p:editor />
	<h:commandButton action="step1" value="step1" />
 </h:form>  
</body>
My web.xml is as follows:

PrimeFaces 2.2 and SWF 2.2 will introduce seamless integration.

What does a primefaces resource url return? You can try with an included resource url that has /primefaces_resource/ in it.

Here is more information about my problem.

When executing the simple flow (just trying to get a single page to display):

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
 <flow xmlns="http://www.springframework.org/schema/webflow"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://www.springframework.org/schema/webflow   http://www.springframework.org/schema/webflow/spring-webflow-2.0.xsd">

   <view-state id="step1" view="step1.xhtml">
   </view-state>

</flow>
The above mentioned page generates the html below. Note: the Javascript function call is generated to create the Prime Faces Editor (PrimeFaces.widget.Editor), however the script tags for the appropriate PrimeFaces resources are not created. Trying to determine why?

Code: Select all

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
<html xmlns="http://www.w3.org/1999/xhtml">

   	<p>This is a step in flow</p>

widget_j_id1721849521_66a156ab_j_id1721849521_66a15685 = new PrimeFaces.widget.Editor('j_id1721849521_66a156ab:j_id1721849521_66a15685:input',{width:'500px',height:'300px',handleSubmit: true});
widget_j_id1721849521_66a156ab_j_id1721849521_66a15685.render();

//--></script><input id="j_id1721849521_66a156ab:j_id1721849521_66a156f2" name="j_id1721849521_66a156ab:j_id1721849521_66a156f2" type="submit" value="step1" /><input type="hidden" name="j_id1721849521_66a156ab_SUBMIT" value="1" /><input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="e2s2" /></form>  
</body>

</html>
Side note: I am looking forward to the integration of PF and SWF!! Keep up the good work.

You need to use h:head instead of head.

I changed to use h:head, script tags are now generated. Thanks! However I run into another problem. The HTML is now created as follows:

Code: Select all

</html>
With the previously noted configuration. it appears the URLs are being resolved by the URLbasedViewResolver and
being prefixed and suffixed.

For example, In using Firebug, I see a GET perfomed for

http://localhost/SpringFlowTestWeb/spri ... primefaces

an exception is then generated by the web application, because the following file cannot be found:

/WEB-INF/javax.faces.resource/jquery/plugins/ui/jquery.ui.autocomplete.xhtml

Is there additional configuration that needs to be done to resolve the resources differently?


Here is my SWF configuration:

Can you try the Spring WebFlow forums as well, I'll forward this to SWF team.

Here is the solution:

Need to add the "order" property to the SimpleURLHandler so it will process resource requests before flow requests.

Code: Select all

   <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
   		<property name="order" value="0"/>
		<property name="mappings">
		  <value>
		     /javax.faces.resource/**=jsfResourceHandler
		  </value>
		</property>
    </bean>
    <bean class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping">
                                <property name="flowRegistry" ref="flowRegistry"/>
                                <property name="order" value="1"/>
	                <property name="defaultHandler">
		<!-- If no flow match, map path to a view to render; e.g. the "/intro" path would map to the view named "intro" -->	
		<bean class="org.springframework.web.servlet.mvc.UrlFilenameViewController" />
	  </property>
    </bean>

Having updated to using primefaces-2.2.RC1-SNAPSHOT.jar, I now get the following error which is likely due to this .jar version being under development, but just wanted to let you know:

[8/17/10 11:30:16:559 CDT] 0000001c HtmlStyleshee W Resource referenced by resourceName /skins/sam/skin.css and libraryName primefaces not found in call to ResourceHandler.createResource. It will be silenty ignored.
