Visualforce: Issues with $Permission when rerendering

Question

Has anyone else experienced issues with permission based elements on visualforce when rerendering a section?

For example I have a section that for administrators will provide a link but for common users it would just display the text like so:

<apex:repeat id="myRepeat">
    <apex:outpanel id="myWrapper"
    <!-- If user has admin permissions -->
    <apex:outputPanel rendered="{!$Permission.AdminPermission}">
        <a href="/{!record.Id}" target="_blank">
            <apex:outputPanel layout="block">Record# {!record.Id}</apex:outputPanel>
        </a>
    </apex:outputPanel>
    <!-- If user does NOT have admin permissions -->
    <apex:outputPanel rendered="{!!$Permission.AdminPermission}">
        <apex:outputPanel layout="block">Record# {!record.Id}</apex:outputPanel>
    </apex:outputPanel>
    <!-- Input text with onchange actionFunction method -->
    <apex:inputText value="{!rowUnits}" onChange="updateUnits(this)"/>
</apex:repeat>

<!-- Action Functions -->
<apex:actionFunction 
    action="{!setUnits}" 
    name="updateUnitsAction" 
    reRender="{!$Component.myRepeat.myWrapper}">
</apex:actionFunction>

<apex:commandButton value="Submit" action="{!process}" rerender="errors, {!$Component.myRepeat.myWrapper}/>

When the page first loads this works exactly as expected but then when I rerender the section that contains this portion of markup the permission that once worked (granting the link) is now false (showing just the text). If I refresh the page I again have the admin link.

Appreciate any feedback, thanks!

Edited with command button, inputtext onchange, and wrapper section markup

Interesting... the comments and previous answer were very helpful (so thank you for them), I implemented them but the actual issue turned out to be because of the <apex:outputPanel>.

Apparently even without the permissions in play the hyperlink was being removed on rerender because the text was wrapped with an outputPanel. Luckily, I found another section where this was not an issue, it was using <apex:outputText> so I modified my scenario with that and it worked perfectly!

<!-- If user has admin permissions -->
<apex:outputPanel rendered="{!$Permission.AdminPermission}">
    <a href="{!URLFOR($Action.MyObject__c.View, record.Id)}" target="_blank">
        <apex:outputText value="Record# {!record.Id}"></apex:outputText>
    </a>
</apex:outputPanel>
<!-- If user does NOT have admin permissions -->
<apex:outputPanel rendered="{!NOT $Permission.AdminPermission}">
    <apex:outputText>Record# {!record.Id}</apex:outputText>
</apex:outputPanel>

Thanks for you help!

The problem is not there in this section of code which you have shared.

The issue lies how your are re-rendering this section. Are you using click event action function or controller action which is re-rendering these output panels?

If you mind to share the code on how you are re-rendering.
