Re: GWT and annotations from JAXB
I've the same problem. I've followed your instructions and almost everything has been fixed. Except for these errors: [ERROR] Line 36: No source code is available for type javax.xml.namespace.QName; did you forget to inherit a required module? [ERROR] Line 198: No source code is available for type javax.xml.bind.JAXBElement; did you forget to inherit a required module? I've also tried to include sources of stax, with no luck.

XML binding/mapping and GWT-RPC
Hi everyone. I'm writing an app that make intense use (reading/writing) of xml configuration files. My first approach was to use a library that maps/binds xml files into java serializable classes, in order to be used via RPC and having them available at client-side. To be concrete, i have: - server-side: binds xml files to java classes using some kind of library; - shared-side: where business classes resides that are filled up by the server and all are Serializable. Of course shared-side is compiled to js. But i'm stucked. I've dig around and tried a lot of libraries (JAXB, Xstream, XMLBeans...) that should makes this kind of things easier but, unfortunately, it seems to me that every one relies on reflection in some ways and while i can still use them in server-side, when i try to serialize them to the client, a lot of issues came up, because reflection is not part of the jre subset that can be freely compiled to js (am i right?). So, i was wondering if there a way to use such tools (whatever) and continue using the whole GWT-RPC mechanism and object serialization to client- side. Are there any better solutions?

Re: XML binding/mapping and GWT-RPC
I need to manage xml files (already written), so i thought that having them binded into serializable POJO's was a good choice. But none of the technologies mentioned seemed to work in that way. For example with JAXB you can autogenerate java classes from xsd schema, having them serializable and usable through gwt rpc service. But it doesn't work bacause of reflection. Xstream and XMLBeans is the same. Am i missing something?

This is exactly what i want to do. But i can't figured it out how. Binding into POJOs at server-side (XMLs are huge) and having them available at client side through serialization, is wrong?

Re: XML binding/mapping and GWT-RPC
I've seen that project (and it's quite amazing) but its purpose is client-side mapping using deferred binding. And i don't want to parse 15K LOC client-side... And it does not (yet :D) generate xml from the annotated classes. Thanks anyway. ciosbel.

Re: showing all the elements from SuggestOracle in suggestionBox
Instead defining your own oracle (which is, indeed, the best
solution), just use a MultiWordSuggestOracle.
There you can find methods like:
setDefaultSuggestions(Collection
suggestionList)
or
setDefaultSuggestionsFromText(Collection
suggestionList)
You can simply add suggestions to you oracle (oracle.add ...) and then
use one of the above to set default suggestions.
Now, using yourSuggestBoxInstance.showSuggestionList(), *all* your
suggestions will popup.
Remember that the oracle that provides suggestion and the default set
you specified using one of the above are two different things, with
two different purposes. So, if your list of suggestions will change in
future (i.e. after a clear/add in the oracle) just remember to reset
the defaults.
If you want to display them *all* on textbox focus...
yourSuggestBoxInstance.getTextBox().addFocusHandler(new FocusHandler()
{
public void onFocus(FocusEvent event) {
// showing all default suggestions
yourSuggestBoxInstance.showSuggestionList();
}
});
Do note also, that with 2.1 milestones the interface of the suggestbox
has been slightly changed. In particular you can now define your own
display for the popup, and use it instead of the default (and a bit
old) one. The custom popup can be defined by either extending
SuggestBox.SuggestionDisplay (if you start from zero), or
SuggestBox.DefaultSuggestionDisplay if you want to start from the
default one.
Hope it helps.
cios.

Re: showing all the elements from SuggestOracle in suggestionBox
I don't suggest you to do that. I think it's quite misleading for the
user. A better solution should be to show a popup with a message like
"no suggestions found" or something like that.
It's quite simple using 2.1 milestones: extend either
SuggestBox.DefaultSuggestionDisplay or SuggestBox.SuggestionDisplay
and override showSuggestions method, checking if suggestions.size() is
zero and displaying a "no suggestions found" popup instead of the
default one.
If you really want to implement the behavior you mentioned, maybe this
hint could be useful too, but atm i have no idea on how to do that.

Of course it is possible. See live demos http://allen-sauer.com/com.allen_sauer.gwt.dnd.demo.DragAndDropDemo/DragAndDropDemo.html The demo 8 should tell you how (see java sources). I think you have to tell the drag controller to make a given panel draggable by a given child. i.e. // make the panel draggable by its header dragController.makeDraggable(verticalPanel, header); Hope that helps.
