I'm trying to use DOM rewriting for the purpose of modifying the content of some grid cells. I modified GridCell class adding a
void afterRender(MarkupWriter writer) method, and in it I can retrieve the Element (org.apache.tapestry5.dom.Element) containing the value I want to modify. For ex. the toString() of one of these Element-s returns: <div id="cellId_xyz_123">Hello</div> But I'm not sure how to change that "Hello" into something else. The Element class doesn't seem to me to have methods for that. If I do Node node = element.getChildren().get(0); I do get a org.apache.tapestry5.dom.Node representing the element's content (its toString() just returns "Hello"), but even this Node object doesn't seem to me to have methods to change its content. Or maybe I should create a new Node instance containing the text I want and then use this instance to replace the existing Node instance in the children list, like element.getChildren().set(0, newNode); ?
