Extension Proposals for F2F

I would like to discuss the following proposals:

  
Finish the Multiphase Render proposal (HEAD section markup)

  

  
Export Registration Properties - Allow a complete propagation of
a producer.

  
    
Currently it is not possible to recreate a producer's
registration on a different producer

    

    
Use case - Propagate a producer from staging to production

    

    
      
Staging Producer Setup

      

      
        
Register with a staging producer, with registration
properties

        

      
      
        
Configure some portlets

      
      
Export from Staging

      

      
        
Export the the Registration Properties

        
Export the configured portlets

      
      
Import to Production

      

      
        
Register the producer, using the exported properties

        
Import the portlets

      
    
  
  
Make WSRP portlets more XMLHttpRequest (Ajax) friendly

  
    
This is currently more of a discussion point than a set of
specific extensions

    
We have found issues with the following:

    
      
WSRP URLs are not rewritable

      
        
resource URLs

        
          
resource-id

          
wsrp-url

          
both

        
        
Perform Blocking Interaction

      
      
There is no way to tell the consumer to not send other markup
(other portlets and page markup)

      
There is no way for the consumer to tell the producer this is
an XHR request

      
        
May require different handling by the producer and/or
portlet

        
There is no way for the producer to determine if multiple
requests are part of a single client-consumer request

        

      
      
What to do when there's IPC - Should other portlets' markup
be processed

      

      
        
Events

        
Shared Parameters

      
    
    
Use Cases:

    
      
Simple Type Ahead (no portlet state required)

      

      
        
The user starts type and matching words automatically
appear in the text box

        
          
E.g. Type "Co" and "Colorado" is entered for you

          

        
        
The portlet sends a XHR to a resource URL

        
          
Via the wsrp-url

          

          
A GET parameter is tacked on to the URL

        
        
The response is XML or JSON which the client-script process
and places in the text box

        

      
      
Type ahead based on a portlet's navigational state

      
        
Type "Ha" and "Hamburger" appear in box (based on a
previously entered value)

        

        
The portlet sends a XHR to a resource URL

        
          
 Via resource id 

          

          
A Get parameter is tacked on to the URL

        
        
The response is XML or JSON which the client-script process
and places in the text box

      
      
Wizard Style Forms

      
        
The user enters form values and presses "Next", the next
page of the wizard appears

        
The portlet sends a XHR to a performBlockingInteraction URL

        
          
Parameters may be

          
            
GET parameters tacked on the URL

            
POST parameters in the stream

            

          
        
        
The portlet saves its navigational state to include the new
parameters and its place in the form

        
The response is HTML which the client uses DOM manipulation
to update the page 

        

        
          
div.innerHTML = request.responseText

          

        
        
On a page refresh the portlet will return the HTML (via
getMarkup) with user on the same page  and previously submitted values
are accounted for

        

      
      
Table Manipulation

      
        
The user adds rows to a table, the page keeps track of the:
sum, user average and company average

        

        
          
The user enters a number and presses "Add"

          
The table updates displaying a row for the new number and
updates the sum and averages

        
        
A parameter may be

        
          
a GET parameter tacked on the URL

          
a POST parameter in the stream

          

        
        
The portlet saves its navigational state to include the
value

        
The portlet calculates the sum and averages and returns
their values as JSON or XML

        
The response is JSON or XML which the client uses DOM
manipulation to update

        
          
data = "eval("(" + request.responseText + ")")

sumNode.innerHTML = "<b>" + data.sum + "</b>"

userAvgNode.innerHTML = "<b>" + data.userAvg +
"</b>"

companyAvgNode.innerHTML = "<b>" + data.companyAvg +
"</b>"

          

        
        
On a page refresh the portlet will return the HTML (via
getMarkup) with the user's data and the current sums and averages
