If you have some elements (or even the whole page) that flash/twinkle using RichFaces, it probably means that these elements are AJAX-rendering. The question is by whom and how to fix it?
A lot of tags in RichFaces can AJAX-render elements such as:
<a4j:form>
<a4j:jsFunction name="updateName" reRender="showname">
<a4j:actionparam name="param1" assignTo="#{userBean.name}" />
</a4j:jsFunction>
</a4j:form>
On the above example, the JavaScript function updateName will AJAX-render the element which has the ID showname.
In some cases, you would have some elements that would AJAX-render without asking them to do so!
I still didn’t figure it out why. 🙁 (if anybody has an idea, please don’t hesitate to tell me!)
But, I found a way to prevent this!
You simply can add the following attribute to your tag:
limitToList="true"
You even can add it to the tags that don’t have a reRender attribute.
For example:
<a4j:form>
<a4j:poll id="poll" interval="1000" limitToList="true" />
</a4j:form>
