Subject Re: Tomahawk Partial rerender datatable column
Date Fri, 26 Oct 2012 16:29:38 GMT
I'm not sure why you had "*textVehicleName*"

If it can work, it should simply be

<a4j:support event="onchange" reRender="textVehicleName"/>

If that doesn't work, it probably can't be done with a4j and JSF 1.2.
 I'm fairly certain I did something similar back when I was using the
Richfaces 3.3 a4j and JSF 1.2.
