First, thank you to your demo.

Second, ... a bunch of questions :) But only 2 questions this time. Do you use any JSF component which is in RF 3.2 but not in RF 3.1? If yes, what is it?
Do you use the file upload component from Seam? If yes, is it ajax-like (i.e. you can upload the file while doing something else on the screen)? Sorry for this kind of question, I don't have time to learn Seam (although that's what I want).

I think calendar is RF 3.2 and not in 3.1. We use tomahawks file upload. No ajax functionality, but it satisfied our needs.

Okay. What's the idea of conversationPropagation=begin.client (etc...)

We work with pageflows and call "programs" from jsp page with s:link

example

<s:link view="#{item.entitet.link}" pageflow="#{item.entitet.pageflow}" propagation="begin" styleClass="posaoKatalog" value="#{item.entitet.naziv.naziv}" />

off course pageflow name is store in database and access via bean...

one simple pageflow (Criteria) look like this

<pageflow-definition xmlns="http://jboss.com/products/seam/pageflow"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Thanks, looking forward to see how image upload is implemented

jsp page (in modal panel)

<h:form id="formaPromjeniSliku" enctype="multipart/form-data">
 <t:panelGrid columns="2">
 <t:graphicImage url="#{osoba.slika}" border="0" />
 <t:commandButton id="uploadGumb"

we store image on disk because later we will go on database witch doesn't support blob

Thanks for the example :)

Now that you see example in file upload, do you have better solution?

[dmitry.demyankov]

I didn't have time yet to test it in my application. I guess when I'll implement some other features I'll be working on user images. That's when I'll be needing file upload. So I'll just post my results here later :)

So far thanks again for your help!
