    RichFaces Ajax not raising onchange event when selection is

    Ashok Kumar Newbie

      I am attempting to implement a cascading picklist and am running into JSF event issues.

      The two lists are category and subcategory; there is a separate list of subcategory items for every category item.

      The desired behavior is : When a selection is made from the category list, the subcategory list must be updated to display the corresponding

      The problem I am finding is the JSF 'onchange' event is not being raised reliably when a selection is made from the category drop-down.

      Here's how the facelets .xhtml is set up

      <a4j:outputPanel id="categoryPanel">
      <h:selectOneMenu id="businessCategory" value="#{account.businessCategory}">
      <f:selectItems id="businessCategories" value="#{categoryManager.categories}" />
      <a4j:support event="onchange" reRender="categoryPanel,subCategoryPanel"></a4j:support>


      <a4j:outputPanel id="subCategoryPanel">
      <h:selectOneMenu id="businessSubCategory" value="#{account.businessSubcategory}">
      <f:selectItems id="businessCategories" value="#{categoryManager.getSubCategories(account.businessCategory)}" />

      The problem is showing up in the Spring Webflow 2.0 + RichFaces environment. I do want to mention that the above scenario is working
      as expected in the JBoss Seam + RichFaces environment

      Any help on how I can resolve this, or any other suggestions are greatly appreciated.
