For anybody trying to do something similar, my working code (using
event.preventDefault, and using DeferredCommand did the trick):
//
// Preview events-- look for shift-clicks on paper/author links, and
pops up
// edit dialog boxes:
//
public void onPreviewNativeEvent(Event.NativePreviewEvent pe) {
NativeEvent e = pe.getNativeEvent();
if (Event.getTypeInt(e.getType()) != Event.ONCLICK) { return; }
if (!e.getShiftKey()) { return; }
EventTarget target = e.getEventTarget();
if (!Element.is(target)) { return; }
Element elt = Element.as(target);
String href = elt.getAttribute("href");
if (href == null || href.length() == 0){ return; }
if (href.contains("/paper/")) {
e.preventDefault();
final String paperPID = InterfaceUtils.getPIDFromLinkString
(href, "paper/");
DeferredCommand.addCommand(new Command() {
public void execute() { fetchPaperInfoThenEdit(paperPID); }
});
}
else if (href.contains("/author/")) {
e.preventDefault();
final String authorPID = InterfaceUtils.getPIDFromLinkString
(href, "author/");
Map<String,String> params = InterfaceUtils.parseURLParams(href);
final String fromPaperPID = params.get("fromPaper");
DeferredCommand.addCommand(new Command() {
public void execute() { fetchAuthorInfoThenEdit(authorPID,
fromPaperPID); }
});
}
}
