Hi, I will try to give you an explanation of how it can be done :
1. the pipeline called by the coplet containing the form is something
like this :

<map:match pattern="myForm">
<map:select type="request-method">
<map:when test="GET">
<map:call function="MyFlowFunctionThatCreateAndDisplayTheForm">
<map:call continuation="{request-param:continuation-id}"/>

2. the pipeline showing the form is somewhat like this :
<map:patch pattern="showMyForm">
<map:generate type="jx" src="..."/>
<map:transform type="browser-update"/>

<map:transform type="i18n" label='i18n'>
<map:parameter name="locale"

<map:transform src="somewhere/cocoon forms xsl.xsl" label='forms-xsl'>
<map:parameter name="contextPath" value="{request:contextPath}"/>
<map:parameter name="lang"

<map:select type="request-parameter">
<map:parameter name="parameter-name" value="cocoon-ajax"/>
<map:when test="true">
<map:serialize type="xml"/>
<map:serialize type='xhtml'/>

3. In the template :
<ft:form-template action="portal" enctype="multipart/form-data"
method="POST" ajax="true"

Note :
- I assume that these pipeline are in the portal sitemap. If not, just
modify ajax-action
- We do not use the temporary attribute "application-uri". (the uri of
the coplet is always cocoon://portal/myForm in this case)

I think that's all.

Good luck !
