Hi all,
I've read all the posts about this subject and I understand what the
restrictions are on this subject, however I cannot seem the figure
this one out.
I use the following lines of code(snippets):
RootPanel ccWidget = RootPanel.get("cc_js_widget_container");
ccWidget.setvisible(false);
...
ccWidget.setvisible(true);
VerticalPanel lowerpanel = new VerticalPanel();
Button choose = new Button("Choose this license");
lowerpanel.add(choose);
choose.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
String result =
ccWidget.get("cc_js_result_uri").toString();
showResult(result);
}
});
RootPanel.get("lowerbody").add(lowerpanel);
Now this renders correctly, however is if I click Choose I get the
uncaught exception:
A widget that has an existing parent widget may not be added to the
detach list
If I then click again, this exception does not occur and it goes on a
happy little program.
I stepped through the proces and I get the exception on the line:
String result = ccWidget.get("cc_js_result_uri").toString();
What am I not seeing here?
