I don't know the page you edited to get this, as I don't know the TimeTracker app, but there has always been a problem with components that are in loops, since the id in the html file will not match the id of the html element, since it may have '_x' (where x is an integer) appended to it. Other components just don't use the tapestry id as the id for the corresponding html element. In the case of a loop or table, it is usually easiest (necessary?) to put the entire list or table inside a div and then update that div. In the case of a component that just doesn't match the html id to the component id, a div works very nicely and isn't really any more expensive.
<div jwcid="[EMAIL PROTECTED]" id="descriptionFieldWrapper"> <span jwcid="descriptionField" .../> </div> or <div jwcid="[EMAIL PROTECTED]" id="descriptionFieldWrapper"> <span jwcid="@contrib:Table" .../> .... </span> </div> getBuilder().updateComponent("descriptionFieldWrapper") will then cause the wrapper and the contents to be rerendered. --sam On 12/2/06, sun quanzhi <[EMAIL PROTECTED]> wrote:
