Re: A possible critical bug for gwt-fabridge.
Hi Jihong,
Perhaps a more appropriate place to report this gwt-fabridge bug would be on
the project Issue Tracker. I'm sure the developers behind the project would
be happy to be notified about a potentially critical issue.
http://code.google.com/p/gwt-fabridge/issues/list
Hope that helps,

Hi. I have a problem forgwt-fabridge. I think it may be a critical
issue forgwt-fabridge.
If a swf widget is added into a panel, and then add the panel into a
container. And then remove the panel from the container, and then add
the panel back into the container. Then the Null pointer error will
occur at onInitialization()caused by the swf widget. I did a test
using
the FABridgeDemo. In the FABridgeDemo, I added a button for removing
the
swf widget.
When start the program, first click the Add new SWF, and everything
is
ok. Then click the Remove SWF, then the swf is removed. Then click
the
Add new SWF again, then an error will happen.
I have tried many ways, the only way to make it work is to create the
swf widge again and using a different name if the widget has been
removed. For example:
java.util.Date date = new java.util.Date();
swfWidget = new
SWFABridgeWidget(app.swf,400,400,example+date.getTime());
But it is not good at all. And the behavior is not the same as other
regular gwt widgets. For other widgets, after they are put in a
panel.
Then you can add/drop this panel into/from a container many times
without re-create the inside widgets.
I am really frustrated about this problem. Based on user's selection
we
will add different panels into a container for display. It is really
painful if we have to create the swf widgets again if the panel has
been
dropped from the container once.
I don't know whether the following code in
pl.rmalinowski.gwt2swf.client.ui.SWFWidge causes problem or not.
protected void onUnload() {
// GWT.log(onUnload, null);
getElement().removeChild(DOM.getFirstChild(getElement()));
isSWFInjected = false;
super.onUnload();
}
The statement:
getElement().removeChild(DOM.getFirstChild(getElement()))
removes the child from the widget. Thus after a swfwidget is removed
from a panel, and then add the swf back, no child there.
Following is the code in com.google.gwt.user.client.ui.ComplexPanel
@Override
public boolean remove(Widget w) {
// Validate.
if (w.getParent() != this) {
return false;
}
// Orphan.
orphan(w);
// Physical detach.
Element elem = w.getElement();
DOM.removeChild(DOM.getParent(elem), elem);
// Logical detach.
getChildren().remove(w);
return true;
}
It sounds to me that the different between two programs is that in
ComplexPanel, it removes the widget's element only, but in SWFWidge,
it
removes the child of the widget's element.
Thank you very much!
