Hi,
what does a "IllegalStateException" mean for a DialogBox?
java.lang.IllegalStateException: This widget's parent does not implement
HasWidgets
at
com.google.gwt.user.client.ui.Widget.removeFromParent(Widget.java:204)
at com.google.gwt.user.client.ui.PopupPanel.show(PopupPanel.java:1016)
at com.google.gwt.user.client.ui.DialogBox.show(DialogBox.java:432)
at com.google.gwt.user.client.ui.PopupPanel.center(PopupPanel.java:523)
I'm trying to just show the following custom dialog composite:
MyDialog.java:
class MyDialog extends Composite {
@UiField
DialogBox dialog;
public MyDialog() {
initWidget(..);
dialog.show(); //Exception
}
}
<g:FlowPanel>
<g:DialogBox ui:field="dialog">
<g:HTMLPanel>somestuff</g:HTMLPanel>
</g:DialogBox>
</g:FlowPanel>
MyModule.ui.xml (main module with Entry point):
<my:MyDialog />
