title: JSF a4j:support with h:selectManyCheckbox
body: <p>I'm having trouble with a JSF selectManyCheckbox and A4J support. The purpose is to run some action when a checkbox is selected. This works perfectly in Firefox. Yet, when testing in any IE (ie6 / ie7 / ie8), found out that the action was being called but the selected value was put to null. Just to test it, I placed a JSF commandButton to submit the form and to check the value that was selected and it was correct. So the problem is really in the ajax action (without submiting the form).
  Here is my code:</p>
  
  <pre><code>        &lt;h:selectManyCheckbox id="supportCategoryCardFilter" value="#{cardListProvider.categoriesHolder.selectedCategories}"  layout="pageDirection" required="false" &gt;
              &lt;f:selectItems value="#{cardListProvider.categoriesList}" /&gt;
              &lt;a:support ajaxSingle="true" status="statusSearchCard" id="supportCategoryCardFilter2" event="onclick" reRender="cardsHolder, renderCardsCategoriesPanel" 
                   action="#{cardListProvider.findCards(cardListProvider.categoriesHolder.selectedCategories)}"  &gt;
              &lt;/a:support&gt;
          &lt;/h:selectManyCheckbox&gt;
  </code></pre>
  
  <p>where <code>cardListProvider.categoriesList</code> is a <code>List&lt;SelectItem&gt;</code> and <code>cardListProvider.categoriesHolder.selectedCategories</code> is a <code>List&lt;String&gt;</code></p>
  
  <p>Has anyone had this problem? Can anyone help me with this?
  Thank you</p>
