How to get whole bizData (or contextObject) object from javascript flow function?

Hi,

 From a java class I call:

pipelineUtil.processToStream("render/renderPage", bizData, fos); [1]

Because I need to use java inside the jxTemplate, I needed to add a 
javascript flow function to call the jxTemplate pipeline. My problem is 
I don't know how to get the whole bizDataObject from javascript flow, so 
far I found:

Packages.org.apache.cocoon.components.flow.FlowHelper.getContextObject(objectModel); 
[2]

Should return the bizData object.

My question is how to get the objectModel inside a flow function to to 
call FlowHelper.getContextObject() ?

Best Regards,

Antonio Gallardo.

Ignore that... I just re-read your post and saw that I misunderstood 
your problem.

Can you add another level of indirection?:

	final Whatever data = whatever;
	pipelineUtils.processToStream (
			"render/renderPage",
			new Object() {
				public Whatever value = data;
			},
			fos
		);

Then in your JXT, ${value} is the object you want.

[SOLVED] Re: How to get whole bizData (or contextObject) object from javascript flow function?

Eric Meyer provided the solution:

Send the bizData as a request Attribute and retrieve it back in the flow 
function.

In the below sample, before calling

pipelineUtil.processToStream("render/renderPage", bizData, fos)

We added:

    Map objectModel = ContextHelper.getObjectModel(this.context);
    Request request = ObjectModelHelper.getRequest(objectModel);
    request.setAttribute("bizData", bizData);

   Then in the flow function we retrieved the bizData as follows:

var bizData = cocoon.request.getAttribute("bizData");
cocoon.sendPage("render/renderPageView, bizData);

Best Regards,

Antonio Gallardo.
