How to change order layout of ColumnModel for all of app?

[juan]

I have about 20 columns in real model, but I can't seem to order it the why I want to. I want to order them how I have them in the list.

<ColumnModel ID="colModel">
    <Columns>
        <ext:Column ID="firstColumn" runat="server" Text="ticket#" Width="85" Sortable="true" DataIndex="ticketID" />
        <ext:Column DataIndex="secondColumn" Text="value2#" ItemID="ValueNo" Visible="False" Width="85" />
        <ext:Column DataIndex="thirdColumn" Text="value3#" Width="75" ItemID="value3#" Visible="False" />
        <ext:Column DataIndex="fouthColumn" Text="value4#" ItemID="value3#" Flex="1" Visible="False" />
        <ext:Column DataIndex="fifthColumn" Text="value5#" />
        <ext:Column DataIndex="sixthColumn" Text="value6#" Flex="1" />
        <ext:Column DataIndex="seventhColumn" Text="value7#" Flex="1" />
        <ext:Column DataIndex="eighthColumn" Text="value8#" Flex="1" />
</ColumnModel>

Is this caused by the stateful of grid?
