Re: Problem with continuation bookmark in flowscript/jxt

Wed, 05 Jul 2006 10:09:17 -0700

Hi,
I may be wrong here but that sure looks like overkill to me. I am generating a continuation using:

var form = new Form("forms/CreditCardDetails.xml");
form.showForm("CreditCardDetails.xml", {"userGlobal":userGlobal});
var model = form.getModel();
var bizData = {"fname" : model.fname, "lname" : model.lname, "account_no" : model.account_no, "credit" : model.credit, "month" : model.month, "year" : model.year}

var bkm = cocoon.createWebContinuation();

I then pass the continuation via:

cocoon.sendPageAndWait("orderFail.xml", {bookmark:bkm})

The continuation id is populated in the form:

<tr>
    <td>  
	<form method="post" 
action="17172c756e3d405c52181710165f36741a190b48.kont">
	   <input
 type="submit" name="back" />
	</
form>
    </td>
</tr>

I click submit, and POW!!!! Now what I would like to know is why the above method does not do what I expect it to?

Andrew

Ard,
sorry, I still don't get it!! In 
  the context of:

var bkm = 
  cocoon.createWebContinuation();
......

cocoon.sendPageAndWait("orderFail.xml", 
  {bookmark:bkm, "OrderDetails":neworder, "transaction_message": 
  response.getCVV2Code()});

how do I implement :

Form.prototype.sendFormAndWait = function(){
}

?

Hello 
    Andrew,

    
 

    
take a look at Form.prototype.sendFormAndWait in  Form.js in the cocoon 
    code. Think you will get the idea if you look at that 
    one,

Hi,
I 
      am having some problems implementing a continuation bookmark. Basically a 
      user enters some form details and submits the details:

function 
      confirmStage() {    
    //2. Get card 
      details.
    var form = new 
      Form("forms/CreditCardDetails.xml"); 
    
      form.showForm("CreditCardDetails.xml", 
      {"userGlobal":userGlobal});
    var model = 
      form.getModel();
    var bizData = {"fname" : 
      model.fname, "lname" : model.lname, "account_no" : model.account_no, 
      "credit" : model.credit, "month" : model.month, "year" : 
      model.year}
    
    //2b. Create 
      bookmark just incase users order is rejected
    var bkm 
      = cocoon.createWebContinuation ();
    
  
      
Later in the same function a check is done to determine whether a 
      users details are valid. If not the user is redirected to a fail page 
      informing them of the failed transaction and providing them with a link to 
      go back to the page/state they were before they submitted their details: 
      

            
          //Credit card was not accepted. Direct user to enter 
      another card.
            
          cocoon.sendPageAndWait("orderFail.xml", {bookmark:bkm, 
      "OrderDetails":neworder, "transaction_message": 
      response.getCVV2Code()});

orderFail.xml:

    
              <tr>
    
                  <td>  
      
            
              <form method="post" action="" href="http://bookmark.id" target="_blank" >bookmark.id 
      }.kont">
        
                  
          <input type="submit" />
    
                  
          </form>
        
              </td>
    
              
      </tr>

sitemap:

        
          <map:match pattern="**.kont"> 
      
               
      <map:select type="request-method">
    
                  
       <map:when test="POST">
    
                     
      <map:call continuation="{request-param:continuation-id}"/> 
      
            
           </map:when>
    
                  
       <map:otherwise/>
        
             </map:select>
    
              </map:match>

when I 
      click the submit button I get the following trace read. What am I missing 
      here?:
