[SalesForce] ActionSupport not updating select list

I have a lookup field and a select list. After selection of a record on the lookup field, a select list should be populated. My updatingAddressOptions() method is called but my getAddressOptions() is never called on rerender, thus never getting the most recent select options.

<apex:pageBlockSection>
        <apex:outputLabel value="Targeted District" for="SchoolDistrict"/>
            <apex:actionRegion>
                <apex:inputField id="SchoolDistrict" value="{!Consultant_Request__c.Targeted_District__c}" required="false">
                    <apex:actionSupport event="onchange"
                            action="{!updateAddressOptions}"
                            rerender="AccountAddressSelect, address, city, state, country, postalcode"
                            focus="AccountAddressesSelect"
                            />
                </apex:inputField>

         <apex:outputLabel value="Account Addresses"></apex:outputLabel>

                  <apex:selectList size="1" id="AccountAddressesSelect" value="{!AccountAddress}">                           
                           <apex:selectOptions value="{!AddressOptions}"/>
                            <apex:actionSupport event="onchange"
                                   action="{!updateAddressFields}"
                                   rerender="address, city, state, country, postalcode"
                                   focus="SiteAddressField"/>
                  </apex:selectList>

             </apex:actionRegion>
</apex:pageBlockSection>

Controller code:

public List<SelectOption> AddressOptions;
public void updateAddressOptions() {

        System.debug('@@@setting address options');
        List<SelectOption> accountAddressOptions = new List<SelectOption>();

       // lots more things happening here

        AddressOptions = accountAddressOptions;
        System.debug('@@@@@AddressOptions in setAddressOptions(): ' + AddressOptions);

    }

    public List<SelectOption> getAddressOptions(){
        System.debug('@@@getting address options');
        System.debug('@@@@@AddressOptions in getAddressOptions(): ' + AddressOptions);
        return AddressOptions;
    }

You need to rerender a container not the actual select list.

change to this:

<apex:outPutPanel id="AddressSelect_Wrapper" layout="inline">
<apex:selectList size="1" id="AccountAddressesSelect" value="{!AccountAddress}">                           
                           <apex:selectOptions value="{!AddressOptions}"/>
                            <apex:actionSupport event="onchange"
                                   action="{!updateAddressFields}"
                                   rerender="address, city, state, country, postalcode"
                                   focus="SiteAddressField"/>
                  </apex:selectList>
</apex:outPutPanel>

Then rerender the "AddressSelect-Wrapper>

[SalesForce] Visualforce SelectList value not setting on Rerender

No need to set the userType as a param on the action function....since the action function and the select list is within the same form section, userType will automatically get set. Also, you can set actionFunction's action="{!null}". It wants an action in there, but all we're really saying is "do the post and rerender the screen". Also note that field validation will occur before the sets...so if you had an input field set to required within the same form tags, your process would fail with no feedback (unless you had a pageMessages tag within the rerendered section)

The error is coming from your query for dist, specifically the where clause:

Region__c =: integer.valueof(apexpages.currentpage().getparameters().get('Regn'))

'Regn' is null when the page loads. Additionally, there appears to be a problem with your page DOM. The way it is structured, I don't think you'll get your getters and setters working in tandem they way you want. I've refactored your code a bit. The VF may not be entirely correct for your case since we're only seeing a snippet. But with this refactor, you can leverage the setter for regn properly and rerender the dist picklist using actionsupport. Also, I've added in a blank initial value for regn and dist so that the user is forced to make a selection, thus firing the onchange event.

<apex:page Controller="UserStatsController">
    <apex:sectionHeader title="Goal Revision Dashboard" subtitle="District View"/>
    <apex:form >
        <apex:pageBlock title="User Stats">
            <apex:pageBlockSection>
                <apex:pageBlockSectionItem>
                    <apex:outputLabel value="Region" />
                    <apex:selectList value="{!regn}" size="1" id="region" required="true">
                        <apex:selectOptions value="{!valuesr}" />
                        <apex:actionSupport id="actionSupport" event="onchange" reRender="districtSelect"/>
                    </apex:SelectList>
                </apex:pageBlockSectionItem>
            </apex:pageBlockSection>
            <apex:pageBlockSection id="districtSelect">
