the render- Tag in my Webflow?! I think in the swf documentation they say , that render- Tags can still used in combination
with jsf 2.0?! Do you know?

Well, SWF seamlessly integrates with JSF 2.0, please refer this link ,
Handling Ajax Events In JSF 2.0

HTML Code:

---

<view-state id="reviewHotels">
    <on-render>
        <evaluate expression="bookingService.findHotels(searchCriteria)"
                  result="viewScope.hotels" result-type="dataModel" />
    </on-render>
    <transition on="next">
        <evaluate expression="searchCriteria.nextPage()" />
        <render fragments="hotels:searchResultsFragment" />
    </transition>
</view-state>

---

There is no transition to for such a JSF action and it means its ajax request and partial rendering is handled using <render fragments="hotels:searchResultsFragment" /> which declares all those client side id's which need to be re-rendered, quite similar to the update attribute of <p:commandButton>.

Hope this helps..

Thanks,
Vijay

I am using JSF with SWF, hence mostly I use <p:commandButton action="some_state" />, I am not sure how to invoke any flow in embedded mode passing url parameters.

I know <input> params to all flows are request parameters, is there any other way?

I have to try this for main flow, currently the example showed the subflow should be called in embedded mode and not the main flow. So I am bit confused here..

Thanks,
Vijay

This works for me <a href="main?mode=embedded">Main flow in embedded mode </a>, is there any JSF+SWF way to do this?

I mean I would like to call a subflow in embedded mode, what configuration will work for me in the flow definition file??

Thanks,
Vijay

With a command button :

PHP Code:

---


<p:commandButton action="myAction">
   <f:param name="myParam" value="myValue" />
</p:commandButton> 


---

With a command link :

PHP Code:

---


<p:commandLink action="myAction">
   <f:param name="myParam" value="myValue" />
</p:commandButton> 


---

you can then access those parameters in the flow definition file through the requestParameters variable for example:

PHP Code:

---

 <subflow-state id="myAction" subflow="mySubflow">
        <input name="myParam" value="requestParameters.myParam" />
      
    </subflow-state> 


---

Thanks Ufasoli,

I tried that.. but

HTML Code:

---

<?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="test">               
                <transition on="test" to="main-flow" />
        </view-state>


        <subflow-state id="main-flow" subflow="main">
                <input name="mode" value="'embedded'" />               
                <transition on="end" to="test" />
        </subflow-state>
       
        <end-state id="finish" />

</flow>

isn't working.... ???

Thanks,
Vijay

do you need to go through the webflow navigation ? or you just need a way to output a link in a JSF way?

If you just need to output a link you can use outputLink

PHP Code:

---

<h:outputLink value="myFlow">
            <h:outputText value="myLink" />
            
            <f:param name="mode" value="embedded"/>
       </h:outputLink> 


---

this will render :

PHP Code:

---


<a href="myflow?mode=embedded">myLink</a>

Thanks for that quick reply, I saw that this works.. but I was curious to figure out the spring web flow navigation way.

Thanks,

humm I see have you tried setting your commandButton to not be executed in ajax mode

PHP Code:

---

 <p:commandButton action="myAction" ajax="false" /> 


---

PHP Code:

---

    <h:form id="form">
            
                
                <h:commandLink value="test - doesnt work" action="test">
                    <f:param name="mode" value="'embedded'"/>
                </h:commandLink>
                    
                <a href="main?mode=embedded">test - this works</a>
                
        </h:form> 


---

PHP Code:

---

<?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="test">        
        <transition on="test" to="main-flow" />
    </view-state>


    <subflow-state id="main-flow" subflow="main">
        <input name="mode" value="requestParameters.mode" />        
        <transition on="end" to="test" />
    </subflow-state>
    
    <end-state id="finish" />

</flow>

I am just curious this doesn't work why???

Thanks,
Vijay

Was the parent flow started in embedded mode?
I think you need to remove the single quotes in your xhtml page change

PHP Code:

---

 <f:param name="mode" value="'embedded'"/> 


---

into

PHP Code:

---

 <f:param name="mode" value="embedded"/>
