Hello,
My aim is to show filtered data in table where filter depends on request parameter. That data might be large therefore I don't want to store it in the session. I have hard time trying to pass that request parameter to filtering java code. So I created separate session bean that contains only one string for that parameter and I added it to backup bean, which performs filtering:
public class AType {
private String type;
// getter & setter
}
public class ActivityController {
private AType atype;
//...
public List<Activity> getAll() {
String type = atype.getType();
System.out.println("Type = " + type);
if ("future".equals(type)) {
return getFutureActivities();
} else {
return getTodayActivities();
}
}
}
I'm obtaining the parameter in this way:
<f:metadata>
<f:viewParam name="type" value="#{activityController.atype.type}" />
</f:metadata>
<ui:composition template="WEB-INF/pages/template.xhtml">
<ui:define name="body">
<f:view>
<h:form>
<rich:extendedDataTable ... value="#{activityController.all}"
var="item" >
...
The problem is that for some reason activityController.atype.type is usually initialised twice - firstly the right value is set and after that (but not always) its previous value is set. So I have to press links many times before I reach desired page. But when I change URL (not clicking at the link), everything works in the proper way.
What's wrong with this, what do I do wrong?
P.S. btw links on which I pressed were added in this way:
<h:outputLink value="activities.xhtml?type=future">
<h:outputText value="Future Activities"></h:outputText>
</h:outputLink>
