RE: Problem with continuation bookmark in flowscript/jxt

Wed, 05 Jul 2006 09:49:53 -0700

I mean that the following piece of code has the behavior you want I think:
 

var comingBack = false;

var bookmark = cocoon.createWebContinuation(ttl);

// Attach the form to the continuation so that we can access by just knowing the continuation id

bookmark.setAttribute("form", this.form);

if (comingBack) {

// We come back to the bookmark: process the form

if (finished && cocoon.request.getParameter("cocoon-ajax-continue") != null) {

// A request with this parameter is sent by the client upon receiving the indication

// that Ajax interaction on the form is finished (see below).

// We also check "finished" to ensure we won't exit showForm() because of some

// faulty or hacked request. It's set to false, this will simply redisplay the form.

return bookmark;

}

if (this.restoreHook) {

this.restoreHook(this);

}

var formContext = new Packages.org.apache.cocoon.forms.FormContext(cocoon.request, this.locale);

// Prematurely add the viewdata as in the object model so that event listeners can use it

// (the same is done by cocoon.sendPage())

// FIXME : hack needed because FOM doesn't provide access to the object model

var objectModel = org.apache.cocoon.components.ContextHelper.getObjectModel(this.avalonContext);

org.apache.cocoon.components.flow.FlowHelper.setContextObject(objectModel, viewdata);

finished = this.form.process(formContext);

if (finished) {

this.isValid = this.form.isValid();

var widget = this.form.getSubmitWidget();

// Can be null on "normal" submit

this.submitId = widget == null ? null : widget.getId();

if (cocoon.request.getParameter("cocoon-ajax") != null) {

// Ask the client to issue a new request reloading the whole page.

// As we have nothing special to send back, so a header should be just what we need...

// e.g. cocoon.response.setHeader("X-Cocoon-Ajax", "continue");

// cocoon.sendStatus(200);

// ...but Safari doesn't consider empty responses (with content-length = 0) as

// valid ones. So send a continue response by using directly the HttpResponse's

// output stream. Avoiding this hack would require to put an additional pipeline

// in the sitemap for just sending constant response, which isn't nice.

cocoon.sendStatus(200);

var httpResponse = objectModel.get(org.apache.cocoon.environment.http.HttpEnvironment.HTTP_RESPONSE_OBJECT);

if (httpResponse) {

httpResponse.setContentType("text/xml");

var text = "<?xml version='1.0'?><bu:document xmlns:bu='" +

org.apache.cocoon.ajax.BrowserUpdateTransformer.BU_NSURI +

"'><bu:continue/></bu:document>";

httpResponse.setContentLength(text.length);

httpResponse.writer.print(text);

} else {

// Empty response

cocoon.response.setHeader("Content-Length", "0");

}

FOM_Cocoon.suicide();

}

return bookmark;

}

}

comingBack = true;

viewdata = this.buildViewData(viewdata)

cocoon.sendPage(uri, viewdata, bookmark);

// Clean up after sending the page

if (this.cleanupHook) {

this.cleanupHook(this);

}

FOM_Cocoon.suicide();

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(){
}

?
regards

Andrew

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,
 
Regards Ard

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=""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?:
