Here the code

<a4j:repeat id="valueList" var="listValue" value="#{configEntity.configurationValueList}" ajaxKeys="#{confManagerBean.keys}">
 <a4j:outputPanel id="listValuePanel">
 <ui:fragment rendered="#{listValue.rendered}">
 <h:message for="configurationEntityListValue" warnClass="message_warn" />
 <div style="float:left; margin-left:10px;">|-</div>

 <!-- works -->
 <a4j:commandLink value="remove (no ajaxkeys)"
 action="#{confManagerBean.removeConfigurationValueListItem}"
 ajaxSingle="true"
 reRender="listValuePanel"
 limitToList="true"
 styleClass="resetButton removeItemButton" >
 <f:param name="configurationValueKey" value="#{configEntity.configurationKey}" />
 <f:param name="displayId" value="#{listValue.displayId}" />
 </a4j:commandLink>

 <!-- dont work -->
 <a4j:commandLink value="add entry immediate"
 action="#{confManagerBean.addConfigurationValueListItem}"
 ajaxSingle="true"
 reRender="listValuePanel"
 limitToList="true"
 styleClass="resetButton addItemButton" >
 <f:param name="configurationValueKey" value="#{configEntity.configurationKey}" />
 </a4j:commandLink>

 <h:inputText id="configurationEntityListValue" value="#{listValue.entry}" styleClass="configInput, configInputListEntry">
 <f:attribute name="configKey" value="#{configEntity.configurationKey}" />
 <f:validator validatorId="configurationEntityValidator" />
 </h:inputText>
 </ui:fragment>
 </a4j:outputPanel>
 </a4j:repeat>

...
 keys.clear();
 for(int i=0; i<list.size(); i++) {
 ConfigurationValueListEntry listEntry = list.get(i);
 String displayId = listEntry.getDisplayId();
 if (displayId.equals(displayIdParam)) {
 listEntry.setRendered(false);
 keys.add(i);
 }
 }

 int reRenderIndex = list.size() -1;
 keys.add(reRenderIndex);

Hello.
maybe my post was a bit to complicated, what i really want to do is:

1) add an entry to a list
2) reRender the list BUT only the row that was added(leave the rest of the list)

For removing entries from list - if found a solution with a4j:repat and ajaxKeys attribute, how to get it to work for add action(is it possible at all)?

A statement on this from a richfaces developer would b really nice.

THx very much,
Holger

Well. i was afraid the answer is that it wouldnt be possible.

So i have to reRender the whole list for add action?
The problem is that the list consist of several input fields which will loose the input made by the user on the add action.

Thats my main problem i got.Any suggestions on this?
(a solution which comes to my mind is to save the input from the field with javascript and to restore values after dom was updated)

I was hoping for some richfaces magic like "just use binding" or "use component state saving that and that way" - if theres any possebility to do that(without wriitng own javascript) - pls tell me.


Thx very much for the quick answer ilya.

Bye,
Holger
