hi!
I'm becoming exasperated because this class sometimes works fine and
sometimes it going crazy. Let's supose this HTML like mine
...
<body>
<div id="frame1">
<div id="frame1.1">
</div>
</div>
<div id="frame2">
</div>
</body>
In method OnModuleLoad() u can refeer with this sentence RootPanel.get
("div_name") to the DIV layer without problems. Then if u do the same
but in another public method, for example u could be refeer to the
frame1 and frame2 layer BUT if u refeer to frame1.1, u will get this
error:
java.lang.AssertionError: A widget that has an existing parent widget
may not be added to the detach list
at com.google.gwt.user.client.ui.RootPanel.detachOnWindowClose
(RootPanel.java:136)
at com.google.gwt.user.client.ui.RootPanel.get(RootPanel.java:211)
at com.my.irn.client.IRn.DisplayResults(IRn.java:398)
at com.my.irn.client.IRn.Paginar(IRn.java:450)
...
Why is hapenning with this class? Can I try another way to setWidgets,
setVisibility, etc to the DIVs layer.
