Hiding / Showing frames

[mulesh]

How can I get a frame to show/hide itself based on a condition?

XML
<Button name="buttonA" hidden="false">
    --Anchors, Sizes, and Layers--
    <Scripts>
        <OnUpdate>buttonA_OnUpdate()</OnUpdate>
    </Scripts>
</Button>

LUA
function buttonA_OnUpdate()
    if condition() then
        buttonA:Show();
    else
        buttonA:Hide();
    end
end

This does not work. I think because when the frame is hidden the OnUpdate handler does not fire. Could I just make a second frame to hold my OnUpdate and if condition() is true it will show my button?

I tried it, and it works great

    </Scripts>
</Frame>
<Button name="buttonA" hidden="false">
    --Anchors, Sizes, and Layers--
</Button>

LUA
function myFrame_OnUpdate()
    if condition() then
        buttonA:Show();
    else
        buttonA:Hide();
    end
end
