Facelets state saving doesn't handle well programmatic component manipulation
-----------------------------------------------------------------------------
Key: MYFACES-2594
URL: https://issues.apache.org/jira/browse/MYFACES-2594
Project: MyFaces Core
Issue Type: Bug
Components: General
Affects Versions: 2.0.0-beta-3
Environment: myfaces trunk
Reporter: Martin Koci
Priority: Minor
Simple tests (code pasted below) outputs following results:
1) JSP: switchs colums at every click with no problem
2) Facelets with javax.faces.PARTIAL_STATE_SAVING=false - no visual switch
3) Facelets with javax.faces.PARTIAL_STATE_SAVING=true switchs colums at every
click with no problem
Common code from test.jspx and test.xhtml
... jsp: or facelets stuff here ...
<h:form id="form">
<h:commandButton value="Switch columns">
<f:actionListener binding="#{testBean}" />
</h:commandButton>
<h:dataTable id="table">
<h:column>
<f:facet name="header">
<h:outputText value="firstName" />
</f:facet>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="surname" />
</f:facet>
</h:column>
</h:dataTable>
</h:form>
@ManagedBean
@RequestScoped
public class TestBean implements ActionListener {
public void processAction(ActionEvent event) throws
AbortProcessingException {
FacesContext context = FacesContext.getCurrentInstance();
UIComponent table =
context.getViewRoot().findComponent("form:table");
UIComponent column1 = table.getChildren().get(0);
UIComponent column2 = table.getChildren().get(1);
table.getChildren().clear();
table.getChildren().add(column2);
table.getChildren().add(column1);
}
}
