a4j:repeat dos not rerender on element removal
Hi, I have the following problem: I use a4j:repeat to dinamically populate a table, I have also implemented adding and removing buttons to dinamically add and remove rows. I have no problem when adding rows but when removing always the last row is removed when I click the minus command link. On the server-side the right element is removed. Here is the jsp:
<a4j:outputPanel id="containers">
<div class="border"
style="height: 100px; width: 250px; overflow-y: scroll; overflow-x: auto;">
<table class="normalText" border="1">
<tr>
<th class="headerCenter"></th>
<th class="headerCenter">?????</th>
<th class="headerCenter">??? ?? ??????????</th>
<th class="headerCenter"><a4j:commandLink
action="#{controlResultsController.addRow}" reRender="containers">
<h:graphicImage style="border: none" value="/images/plus.gif" />
<a4j:actionparam name="plusTable" value="containers"></a4j:actionparam>
</a4j:commandLink></th>
</tr>
<a4j:repeat value="#{goodsItemIE518.containers}" var="GIContainers">
<tr>
<td></td>
<td><h:inputText size="5" value="#{GIContainers.containerNumber}"></h:inputText></td>
<td></td>
<td><a4j:commandLink reRender="containers"
style="text-decoration : none"
action="#{controlResultsController.removeElement}">
<h:graphicImage style="border: none;" value="/images/minus.gif" />
<a4j:actionparam name="rowIndex"
value="#{ecs:countRows(goodsItemIE518.containers,GIContainers)}"></a4j:actionparam>
<a4j:actionparam name="minusTable" value="containers"></a4j:actionparam>
</a4j:commandLink></td>
</tr>
</a4j:repeat>
</table>
</div>
</a4j:outputPanel></td>[And the server-side code:
