Resetting picklist value back to none onchange

Question

Picklist 1 values: Yes No

Picklist2 values:

one two three

I was able to attain the rerendering functionality from the below sample code. If I select picklist1 value as "yes", I am able to display picklist2. And now if I select picklist2 value as "three" and change picklist1 value to "No", Picklist2 value is disappeared from the page, so far so good. Now when I change the Picklist1 value back to "Yes", the Picklist2 value is rerendered on page with value as three. I want to reset the Picklist2 value to none. I need similar funtionality to be implemented with all the text and other fields. Any help is much appreciated.Thanks.

Vfpage

<apex:pageblockSectionItem> <apex:inputfield value="{!picklist1}" onchange="reset();"> </apex:pageblockSectionItem>

<apex:pageblockSectionItem rendered = "{!value}"> <apex:inputfield value="{!picklist2}"> </apex:pageblockSectionItem>

<apex:actionfunction name=reset action="{!check}">

Controller

    public boolean value{get;set};
public void check(){    
    if(picklist1 == 'yes')
    { 
    value=true;
    }
    else{
    value = false;
    }
}

Just because picklist2 is not rendered, it still retains its value. If you want it reset back to null each time the picklist1 value is changed, you need to do this yourself.

It looks as though you are already using an onChange function for your picklist1 value called reset(). You don't show that function here, but you need to reset the controller property value for picklist2 in that function. You can do this through an action function or through VF remoting.

EDIT

Just add a line to your check() method that resets the picklist2 value to blank.

public void check(){  
    picklist2 = '';  
    if(picklist1 == 'yes') { 
         value=true;
    }
    else{
         value = false;
    } 
}
