Observer-Pattern in the Portal-Engine

[Jakob Günther <ja...@yahoo.de>]

Hello cocooners,

i try to realize an Observer-Pattern in the Portal-Engine. The idea is 
that the coplets register at a main-component. This component (i would 
prefer a javascript communicating with some pojo's) would fire event 
back to the registered coplets when their calculated data is ready. But 
i dont know how to get the coplets refreshed before sended. I always 
have to refresh the browser and thats of course no solution.

I use cocoon 2.1.9
I fire CopletJXPathEvent's in my JS-Function doEvent

the part of my sitemap:

     <map:match pattern="portal">
        <map:select type="request-param">
        <map:parameter name="parameter-name" value="loaded"/>
                <map:when test="true">
                    <map:act type="auth-protect">
                          <map:parameter name="handler" 
value="portal-handler"/>
                          <map:parameter name="application" value="portal"/>

                        <map:transform 
src="{portal-skin:skin.basepath}/styles/portal-page.xsl">
                            <map:parameter name="user" value="{ID}"/>
                            <map:parameter name="username" 
value="{session:getAttribute(.,'username')}"/>
                            <map:parameter name="title" 
value="{global:mainTitle}"/>
                            <map:parameter name="base" 
value="{portalpath:relative}"/>
                        </map:transform>
                     
                        <map:transform type="cinclude"/>
                        <map:transform type="portal-coplet"/>
                        <map:transform type="portal-new-eventlink"/>
                        <map:transform type="encodeURL"/> 
                        <map:serialize type="html-include"/> 
                    </map:act>
                </map:when><map:otherwise>
                    <map:act type="auth-protect">
                        <map:parameter name="handler" 
value="portal-handler"/>
                        <map:parameter name="application" value="portal"/>
                       
                        <map:generate type="portal" label="content"/>
                       
                        <map:call function = "doEvents"/>
                    </map:act>
                </map:otherwise>
        </map:select>
      </map:match>

I hope, i could describe the problem. Im not that good in english.
