Hi

If you want to handle the before and after topics separately you can do
something like this. Note I am publishing a separate topic for the form
(submitForm) and then handling it using some javascript code


    <s:div id="treeAndSelector" theme="ajax" href="${refreshTreeUrl}"

listenTopics="/refreshTree" executeScripts="true" loadingText=" "/>

    <s:form ...>

... <s:submit type="button" notifyTopics="/submitForm"

                targets="workspaceAjaxContent" executeScripts="true"
                loadingText=" " cssClass="submit">
            <s:param name="value">
                <fmt:message key="Buttons.accept"/>
            </s:param>
        </s:submit>
    </s:form>

<script type="text/javascript">
dojo.event.topic.subscribe("/submitForm", function(data, type, e){
       if (type=="before"){
        //do something before the form is submitted
       }
       if (type=="load")
       {
        //do something after the form is submitted
                //you can publish the refreshTree topic here
                dojo.event.topic.publish("/refreshTree");
       }
   });
</script>

Now your tree will only be refreshed once...

Subject: listen/notify Topics doubt

Hi all!

I have a simple question:

When a div tag contains the "listenTopics" attribute, the associated href is executed *Before and After* the action associated to the tag which invokes the notifyTopics??

    <s:div id="treeAndSelector" theme="ajax" href="${refreshTreeUrl}"

listenTopics="/refreshTree" executeScripts="true" loadingText=" "/>

    <s:form ...>

... <s:submit type="button" notifyTopics="/refreshTree"

                targets="workspaceAjaxContent" executeScripts="true"
                loadingText=" " cssClass="submit">
            <s:param name="value">
                <fmt:message key="Buttons.accept"/>
            </s:param>
        </s:submit>
    </s:form>

When I submit the form it invokes the action form and i have 2 threads invoking "refreshTreeUrl"... I would like to first invoke the action form, and then, notifyTopics. Is it possible??

Thanks.
