Richfaces 4.0 datatable filtering

[psini82]

I have a problem with filtering a rich:datable that not work properly if i set javax.faces.PARTIAL_STATE_SAVING = false,

the problem can be reproduced with the demo of compotent setting the right cotext-param in web.xml.

The proble is that i can't enable PARTIAL_STATE_SAVING because of a bug in the jsf 2.0 .

Is there a work-around?

The proble is that i can't enable PARTIAL_STATE_SAVING because of a bug in the jsf 2.0 .

whic one? maybe you could downgrade JSF 2 itself to some version where there is no such issue?

P.S. https://issues.jboss.org/browse/RF-9333

I have not tried but if i set the partial state to true if i try to render with ajax two combo from the second form in a second form  i obtain a satcktrace

Caused by: java.lang.ClassCastException: javax.faces.component.StateHolderSaver cannot be cast to [Ljava.lang.Object;

13:00:43,609 ERROR [STDERR]     at org.ajax4jsf.component.behavior.AjaxBehavior.restoreState(AjaxBehavior.java:342)

if i disable the partail state is all ok i have tried the jsf2 version : 2.0.3, 2.0.4,2.1.0

if you want me to try another version ask and i will try.

The Exception in the case of PARTIAL STATE =true i resolved hacking the class org.ajax4jsf.component.behavior.AjaxBehavior changing the method

 @Override
    public void restoreState(FacesContext context, Object state) {
        if (state != null) {
            Object[] values =null;
            if(state instanceof Object[]){
                values= (Object[]) state;
                        }else{
                try {
                    Field privateStringField = state.getClass().
                    getDeclaredField("savedState");

                    privateStringField.setAccessible(true);

                    values = (Object[]) privateStringField.get(state);
                } catch (SecurityException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IllegalArgumentException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (NoSuchFieldException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IllegalAccessException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
            super.restoreState(context, values[0]);

            if (values.length != 1) {
                execute = restoreSet(PropertyKeys.execute, values[1]);
                render = restoreSet(PropertyKeys.render, values[2]);

                clearInitialState();
            }
        }
    }

I know that this is not a patch but i'm wondering why the method in this way have the correct behavior. I had to use the reflection because the class javax.faces.component.StateHolderSaver is private.

Can someone help me to write a patch that resolve this issue?

Hi,

Are you using MyFaces?

[psini82]

No i'm using Mojarra

[nbelaevski]

Can you please provide page/beans code to reproduce the problem?

[psini82]

I will try , but for the proble, of filter in a datatable i simple get the showcase demo and punt in the web.xml

<context-param>

  <param-name>javax.faces.PARTIAL_STATE_SAVING</param-name>

  <param-value>false</param-value>

</context-param>

and test the datatable filtering, for the ClassCastException i will post the test case.
