Dependency Picklist Rerender Issues

Hello,

Account_Review__c has three picklist fields, and there are dependency rules defined between them, so options for one field, depends on whats selected in the other.

I am tryign to display the values of these three fields, in a pageblock. But its causing multiple rerenders, because of dependency picklists, and therefore showing wrong results.

Ex. I set values in three fields, and then if i change the first picklist value, the values in second and third picklist shows NULL (per dependency rules) in the dropdown, but doesnt show NULL when i am printing in the page block. See attached images.

What should i do so the values in pageblock, alwasy show the correct picklist values, after rerender. Thanks. 
<apex:page standardController="Account_Review__c">

    <apex:form>
        <apex:pageBlock>
            <apex:inputfield value="{!Account_Review__c.Reason__c}" id="f1">
                <apex:actionSupport event="onchange" reRender="Block1"/>
            </apex:inputField>
            <apex:inputfield value="{!Account_Review__c.Result__c}" id="f2">
                <apex:actionSupport event="onchange" reRender="Block1"/>
            </apex:inputField>
            <apex:inputfield value="{!Account_Review__c.Action__c}" id="f3">
                <apex:actionSupport event="onchange" reRender="Block1"/>
            </apex:inputField>
        </apex:pageBlock>

Hi Sidharth,

this is because you are rerendering the whole pageblock in place of the rerendering the whole pageblock just rerender single inputtype field.

Thanks
