[jboss-user] [JBoss Seam] - <s:cache /> and <h:selectOneListBox />'s

[MikeDougherty]

I'm having a bit of trouble using the s:cache JSF component in combination with my h:selectOneListBox's.

If I place the <s:cache /> tags just after the <ui:define /> tags (just like the Blog example shows), like so


  | <ui:define name="body">
  |   <s:cache key="index" region="pageFragments">
  | ...
  |   <h:form id="foo">
  |     <h:selectOneListBox id="foo" value="#{myFoo}">
  |       <si:selectItems var="foo" value="#{fooList.resultList}" />
  |     </h:selectOneListBox>
  |     <h:commandButton id="select" action="#{select}" value="Select Foo">
  |   </h:form>
  | ...
  |   <h:form id="bar">
  |     <h:selectOneListBox id="bar" value="#{myBar}">
  |       <si:selectItems var="bar" value="#{barList.resultList}" />
  |     </h:selectOneListBox>
  |     <h:commandButton id="select" action="#{select}" value="Select Bar">
  |   </h:form>
  | ...
  |   </s:cache>
  | </ui:define>
  | 

I can select an item from one of the lists and submit the form once. But when I come back to the page I have "" text in the page, and can no longer submit any of the forms on the page.

If I put the <s:cache /> tag directly around each <h:selectOneListBox />


  | <ui:define name="body">
  | ...
  |   <h:form id="foo">
  |   <s:cache key="index-foo" region="pageFragments">
  |     <h:selectOneListBox id="foo" value="#{myFoo}">
  |       <si:selectItems var="foo" value="#{fooList.resultList}" />
  |     </h:selectOneListBox>
  |     <h:commandButton id="select" action="#{select}" value="Select Foo">
  |   </s:cache>
  |   </h:form>
  | ...
  |   <h:form id="bar">
  |   <s:cache key="index-bar" region="pageFragments">
  |     <h:selectOneListBox id="bar" value="#{myBar}">
  |       <si:selectItems var="bar" value="#{barList.resultList}" />
  |     </h:selectOneListBox>
  |     <h:commandButton id="select" action="#{select}" value="Select Bar">
  |   </s:cache>
  |   </h:form>
  | ...
  | </ui:define>
  | 

I can submit the forms but, I have to click the submit button twice. The first time I get "value is not valid" (as if there was no selected item). Pressing the button again, submits the form.

Is there something special I have to do in order to get the <s:cache /> to work with my <h:selectOneListBox /> tags?
