Action Handler not being called component nhhockeyplayer nashua Fri, 14 Nov 2014 05:06:13 -0800 Hi Folks, Can anyone explain this stack trace ? I am implementing a select component within my template. <td width="10%" align="center" nowrap="NOWRAP"> <t:Label for="itemsPerPageSelect">Items Per Page</t:Label> <select t:type="Select" t:id="itemsPerPageSelect" t:clientId="itemsPerPageSelect" id="itemsPerPageSelect" t:model="literal:5,10,15,25,50,100,250,500,1000,5000,10000" t:value="itemsPerPage" onchange="galleryForm.submit()" /> </td> and here is my handler @Component(id = "tableColumnsSelect", parameters = { "value=tableColumns", "clientId=tableColumnsSelect" }) private Select tableColumnsSelect; @OnEvent(value = EventConstants.VALUE_CHANGED, component = "tableColumnsSelect") public Object onActionFromTableColumnsSelect() { logger.info("In tableColumnsChangeListener : "); onActionFromItemsPerPageSelect(itemsPerPage); return homePage; } I cannot get eclipse to hit my breakpoint and this stack trace results I am basing my premise on the notion that components have parameters and pages have properties. This is a GalleryWidget I designed and handler is failing. Am happy to share this component after. Its a nice one... my handlers are in hiccup right now.

Hi Folks,

Can anyone explain this stack trace ?

I am implementing a select component within my template.

<td width="10%" align="center" nowrap="NOWRAP">
    <t:Label for="itemsPerPageSelect">Items Per Page</t:Label>
    <select t:type="Select" t:id="itemsPerPageSelect" 
t:clientId="itemsPerPageSelect" id="itemsPerPageSelect"
        t:model="literal:5,10,15,25,50,100,250,500,1000,5000,10000"
        t:value="itemsPerPage"
        onchange="galleryForm.submit()"
        />
</td>


and here is my handler
    @Component(id = "tableColumnsSelect", parameters =
    { "value=tableColumns", "clientId=tableColumnsSelect" })
    private Select tableColumnsSelect;

    @OnEvent(value = EventConstants.VALUE_CHANGED, component = 
"tableColumnsSelect")
    public Object onActionFromTableColumnsSelect()
    {
        logger.info("In tableColumnsChangeListener : ");
        onActionFromItemsPerPageSelect(itemsPerPage);
        return homePage;
    }

I cannot get eclipse to hit my breakpoint and this stack trace results

I am basing my premise on the notion that components have parameters and pages 
have properties.

This is a GalleryWidget I designed and handler is failing.

Am happy to share this component after. Its a nice one... my handlers are in 
hiccup right now.

Thanks
