It appears you are trying to programatically change a component on the server. However, that seems to require you understand the api for the components. Most components have a paramter:
This is from the component reference for Tapestry 3, for the TextField Component. Parameters Name Type Direction Required Default Description value String in-out yes The text inside the text field. The binding is only updated when the the component is not disabled. Corresponds to the "value" HTML attribute. hidden boolean in no false If true, then the text field is written as a <input type="password"> form element. disabled boolean in no false Controls whether the text field is active or not. If disabled, then any value that comes up when the form is submitted is ignored. Corresponds to the "disabled" HTML attribute. For the same component in Tapestry 4 see: http://tapestry.apache.org/tapestry4/tapestry/ComponentReference/TextField.html The components have a "disabled" parameter. All you have to do is use ognl to disable it: <span jwcid="@TextField" disabled="ognl:editMode == true" value="ognl:newItem"/> I suppose you can iterate through the list of components and modify them, if they support "disableing" them programatically. However, this seems easier.
