Can Anyone Explain This Struts 2 AJAX Strange Refresh Behaviour?

Question

We have the following code (listed below) in our JSP. We are seeing the action configured in the href of the div id=pwcercontainer being called twice. Can't work out exactly why. Replacing the containing sx:div label="Admin Record Deployment" with a plain non-struts div causes the action to be called only once. We can't see anything in the documentation for sx:div that explains this behaviour.

Does anyone know anything about this or have similar experience?

Thanks. NCF

    <sx:div label="Admin Record Deployment" >

     <!-- Div where content will be displayed --> 
     <sx:div id="pwcercontainer" href="%{pwcerAjax}" showLoadingText="false" indicator="recordImage" preload="true">
     </sx:div>

     <div id="loadingContainer"><img id="recordImage" src="images/ajaxLoadingAnimation.gif" style="display:none" alt="loading animation"/></div>

    </sx:div>

Answer 1

I have hit this issue many times now and it is always down to an error on my part. Either returning a fragment that contains the calling piece of code:

<s:url id="getDeployQueue" action="deploymentQueue"  />

<sx:div href="%{#getDeployQueue}" formId="queueForm" executeScripts="true" autoStart="true" updateFreq="3000" preload="false" showLoadingText="false" listenTopics="refreshqueue" id="deploymentQueue" >



    THE CODE RETURNED in HERE CONTAINS THE s:url id="getDeployQueue" duplicating it and resulting in double calls

</sx:div>

Or i have been setting the target attribute of another ajax tag to be an sx:div when I really should be updating it using a dojo topic.

Hope this helps somebody

Hi Neil,

I am having a similar issue.

I have a left panel and a right panel.

Right panel is supposed to refreshe every time I click on the left panel with a different set of parms.

But, when every time I click on left panel, the number of refreshes growing exponentially.

Any Idea what we are doing wrong?
