XPages: Loading Screen while changing Tabs (TabPanel)

问题

I have a TabPanel on my XPage. When i move from one Tab to another, few data is loading and this takes some time.

Is it possible to show a loading screen, while changing Tabs?

Thanks for your help

You should take a look at xe:djTabContainer and xe:djTabPane. That's the XPages extension library versions of the Dojo tab container. It provides support for loading content in all tabs at once or using partial refresh with the option to add a loading message.

Update

Paul Withers commented on the loadingMessage property. It does work with all content. Here's a simple example:

<xe:djTabContainer id="djTabContainer1" doLayout="false">
    <xe:djTabPane id="djTabPane1" title="Tab 1" partialRefresh="true" refreshOnShow="true" partialEvents="true" loadingMessage="LOADING LOADING LOADING">Tab 1</xe:djTabPane>
    <xe:djTabPane id="djTabPane2" title="Tab 2" partialRefresh="true" refreshOnShow="true" partialEvents="true" loadingMessage="LOADING MORE LOADING MORE">Tab 2</xe:djTabPane>
</xe:djTabContainer>

When you switch tabs, you can very briefly see the loading message.

You can use the standby dialog custom control for that:

It basically injects itself into the partial refresh mechanism. If it takes more than a specified duration for any AJAX request, standby dialog will be shown to the user.
