hi,
This doesn't work for me. Myabe becasue I didn't explain how we show
the JSP. In the root panel we added a toolbar and a LayoutContainer
where, depending on the button clicked in toolbar, a different content
is shown. In some cases, inside the layoutContainer we place JSP using
a Frame. ex:
LayoutContainer mainPanel_;
mainPanel_ = new LayoutContainer();
Frame frame_ = new Frame();
frame_.getElement().setId("oldWebFrame");
frame_.setUrl(urlToShow_); //loads JSP into frame
mainPanel_.add(frame_);
After some research I have found that this code works for me:
IFrameElement iframeElement =
(IFrameElement)Document.get().getElementById("oldWebFrame");
Document document =iframeElement.getContentDocument();
Element element = document.getElementById(fieldId);
if (element != null) {
TextAreaElement textfield = element.cast();
textfield.setValue("some text to add");
}
pep.
