help wtih h:selectOneRadio with a4j:support
Hi,
I have the following:
<h:selectOneRadio id="radio" value="#{bean.searchType}">
<f:selectItem itemLabel="One"/>
<f:selectItem itemLabel="Two"/>
<a4j:support event="onchange" action="#{bean.search}" reRender="pg1"/>
</h:selectOneRadio>By default, "One" is chosen because bean.searchType is "One". But I have two problems:
1. Ajax call is only done when "Two" is clicked then "One" is clicked. Why isn't Ajax call done when "Two" is clicked alone?
2. When Ajax call completes, I get this exception:
