a4j:repeat, dataTable, extendedDataTable all have the same problem. During JSF lifecycle the underlying datamodel is accessed

SequenceDataModel.isRowAvailable() line: 171
HtmlAjaxRepeat(UIDataAdaptor).isRowAvailable() line: 266
HtmlAjaxRepeat(UIDataAdaptor).setRowKey(FacesContext, Object) line: 341
HtmlAjaxRepeat(UIDataAdaptor).iterate(FacesContext, UIDataAdaptor$ComponentVisitor, Object) line: 1034
HtmlAjaxRepeat(UIDataAdaptor).encodeAjaxChild(FacesContext, String, Set, Set) line: 496
AjaxRegionRenderer(AjaxChildrenRenderer).encodeAjaxComponent(FacesContext, UIComponent, String, Set, Set) line: 104
AjaxRegionRenderer(AjaxChildrenRenderer).encodeAjaxChildren(FacesContext, UIComponent, String, Set, Set) line: 67

Due to that even an attempt to make the data model bean lazy initialize does not help.

Interestingly the same is not true for child elements, in below example the echo2 method will not be called, even though testBean.rows is called and returns multiple entries:

<a4j:repeat id="detail" value="#{testBean.rows}" var="attr">
<h:outputText value="#{testBean.echo2()}"/>
</a4j:repeat>

Is there any workaround for this or at least perhaps a pointer from the RF team where to look for it?

I'm running into what I believe to be the same issue. I've tried to simplify it as much as possible. I'm new to RichFaces so it may be a lack of understanding, but I've read "Practical RichFaces" and all the docs I can find, still can't figure it out.

I'm also have a <a4j:poll/> on my page and am trying to update some components but not others. What I'm finding is that my dataTable always get encoded on the server side even if its id was not specified in the "reRender" attribute and with limitToList set to true (sounds like repeat, and others would do the same thing).

Here is my basic page:

Hi, RichardTaylor
Maybe you shoud use a4j:poll like this:
<a4j:poll id="poller" ajaxSingle="true" interval="5000" reRender="time1,time2" limitToList="true"/>
You see the attribute ajaxSingle="true"?
May be the defualt value of the attribute is false, so the whole page is refreshed, if you set it true and set limitToList="true", only the ids you defined in reRender will be encode in sever side.

I use

 <rich:tree id="tree" style="width: 980px;" switchType="client" adviseNodeOpened="#{treeSettings.adviseNodesOpened}">
 <rich:treeNodesAdaptor id="product" nodes="#{calculation.product}" var="product">
 <rich:treeNode>
 <rich:simpleTogglePanel switchType="client" label="Product[ID:#{product.productID}]" opened="#{treeSettings.leavesOpened}">

Hi,

Please take a look: https://jira.jboss.org/jira/browse/RF-3341

Thank you for your help.

The solution was that (using still a4j:region with renderRegionOnly="true") I had to put the components to re-render into an

<a4j:outputPanel ajaxRendered="true" id="op">

Unfortunately, I lost the possibility to toggle my simpeTogglePanel. I will downgrae to plain panels.

Sorry, that was a mistake, I can toggle the panels without problem.

b.t.w. limittolist could be used at ajax components instead of a4j:region around them.
