Re: Integrating RequestFactory into an eclipse project
Thanks all for the help, I ended up doing a tedious comparison of my project with DynaTableRf sample and copied the hibernate validator and gwt-servlet.jar from there. After a very frustrating 5 days, I have a working RequestFactory setup, now I can focus on actually implementing the server end. Question: Part of the problem I faced was Uncaught Exceptions with very unhelpful stack traces. The errors ended up being things like, I had an inconsistency in id type between getid and findClazz(id), un- initialized version field, etc. There were no hints whatsoever on the console, I did an extremely tedious comparison of my project with DynaTableRf as I said above to fix this. I'm wondering if this is because I'm missing a configuration that would automatically point out this inconsistencies. Or is there any other approach to hunting the problem? A strategically placed break point on client/server side? Again, thanks for the responses.

Re: Editor returns null values for empty strings after flush?
That was the missing piece for me: the editor framework uses getvalueorthrow!

Re: Editor returns null values for empty strings after flush?
It looks like that it is enough to comment out the if statement in the
ValueboxBase it solved the issue for me. But I am not sure what
collateral damages that imposes to the request factory way of things.
The patch did not break any test (?!?), and the fact that the
TextBoxBase does undo this behavior is a bit scaring:
ValueBoxBase:
/**
* Return the parsed value, or null if the field is empty or parsing
fails.
*/
public T getValue() {
try {
return getValueOrThrow();
} catch (ParseException e) {
return null;
}
}
/**
* Return the parsed value, or null if the field is empty.
*
* @throws ParseException if the value cannot be parsed
*/
public T getValueOrThrow() throws ParseException {
String text = getText();
T parseResult = parser.parse(text);
/* patched to fix inconsistent behaviour
if (.equals(text)) {
return null;
}
*/
return parseResult;
}
TextBoxBase:
@Override
public String getValue() {
String raw = super.getValue();
return raw == null ? : raw;
}

You should patch TextBoxBase and not ValueBoxBase. Or create your own MyTextBox extends TextBox and overwrite the method.

Re: Generating XML
Hi Gary,
I understand that you want to do. From a java object, you want to produce
XML representation.
Ok, you have many framewoks that do this for you.
The 2 solutions i propose to you :
1) Use a standard way ( good practice and a framework support )
Let see JAXB API on Oracle web site because it's a standard way ( JSR
recommendation if i remember )
http://www.oracle.com/technetwork/articles/javase/index-140168.html.
This operation is called Marshaling e.g transforming a java object in xml.
With JAXB you can fine tune the operation.
Download JAXB and its javadoc, set your Eclipse project to add relative
*.jar and javadoc. Then code
2) If you feel that it's a heavy for what you want to do, just override the
toString() method of your java class, in order to produce xml. Here's a very
simple exemple :
class Personn
{
private String firstName, lastName;
.../... constructor(s), getters, setters, methods omitted .../
@override
public string toString()
{
// you can get class fields using introspection if you want to automate the
process
return firstName + firstName + /firstName + lastName + lastName
+ /lastName;
}
}
I hope it helps.
Regards.

Part of my application requires an XML file to be generated from an
object. The XML produced will be small in size and simple in
structure. I could achieve this using elaborate string manipulation
but I suspect there is a better way.
I tried to use the xmlenc (http://xmlenc.sourceforge.net/) library,
but it requires Writer objects to function, which GWT does not
support. Is there an accepted way of XML generation for GWT? Or
perhaps a way to synthesise Writer objects? Initially, I want the XML
output on the console for testing, but eventually it will be stored on
a server/database.
Thanks,
Gary
