Re: How does registerForProxyType works

[Joshua Kappon]

You need to cause a version change on the object to cause an update
EntityProxyChange event.
are you changing the version on the object once one of the clients is
changing it?

Hi All,

During the build process a copy of "jdo-config.xml" is created in the
WAR folder, so m question is what is the name of that file.


Thx in Advanced

Re: weird production compile problem

[pansen]

ok, i found the problem and fixed it in restygwt:
https://github.com/pansen/resty-gwt/commit/d6f63d9146f407fd12e9f1ab4cfccfa0c7a2d154

if someone could help me with that
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/e0f8392cf222a0ef
, i could finalize this in a smarter way.

cheers, andi

Re: How does registerForProxyType works

[Aldo Neto]

Hi,

Thanks for the hint, but unless I'm doing something wrong I'm still not
being notified. Please note that when I say "other clients" I mean different
users working on different machines accessing the same table on the same
server.

As I said, I expected that everyone would be notified when registering
to registerForProxyType(). If this is not the case, the only thing that
comes to my mind is to periodically request for all the entries that I'm
interested. But again, I'd expect to have a way to PUSH the information I
need, and this is what I'm not being able to do.

Am I missing something? Any other idea?

Thanks

Widget not displayed upon change of place

[Harry X]

I have a display region which will display diffrent widgets accpording place 
change event. 
The widgets are simple, haveing a couple of tables in a flowpanel and making a 
async call 
to get some data through RPC. When the place change events are fired by 
clicking 
on a 
navigation tree, sometimes the widgets are not displayed. However, 
A second click on the navi tree will trigger the widget to be displayed.

I think this has something to do with the handling with onStop()/onCancel(), 
but 
not
sure how to debug and change. Do you have any suggestion? Thanks.

Harry

JClassType source and isGenericType()

[pansen]

hi,

assuming i'm in a generator and receive a ``JClassType source`` which
is in that case a ``org.test.Foo``.

then ``souce.isGenericType()`` returns ``null``
but ``source.getParameterizedQualifiedSourceName()`` returns
"org.test.Foo".
whereas ``source.getSimpleSourceName()`` only returns "Foo"

...which is a problem for me.

what can i call to see this is a specialization of a generic? e.g.
something like ``source.base().isGenericType()``.

what can i call to see the specialization of this class - in this case
i want the result of "Bar".

thx a lot, andi

How does registerForProxyType works

[Aldo Neto]

Hi,

I need to implement a dynamic table that is populated based on values of a
given entity on the server by many clients simultaneously. I thought
that registerForProxyType() would solve all problems of mine, but then I
made some quick tests and found that it is not called when a different
client performs changes to that table. Is this correct? I mean, If I have 2
persons working on the same table and one updates an entry there, should I
expect to be notified on both clients? If not, is there an easy way to do
that?

Thanks,
Aldo

Re: How to start a web service which only return plain text with GWT?

[Juan Pablo Gardella]

For this type of service I don't recommend GWT. GWT is for RIA application.
If you need a REST service, make a servlet and return csv directly.

Read about SQL injection too.

CellTree with SingleSelectionModel will not fire event for root node (GWT 2.3)

[Jens]

Hi

I have a CellTree with a SingleSelectionModel, when i click the root
node it gets visually selected but does not fire a
SelectionChangeEvent, the problem is only for the root element.

Has anyone else discovered (is it by design / a bug / me that screwed
up).

My example is quite simple but i cannot post the code as is, but i can
clean it up and post it if required.

Best regards Jens

Licensing

[SS]

When reading the licensing agreement (terms)
I found a reference to the Browser Detect Code as follows

Browser Detect v2.1.6   Creative Commons Attribution 1.0
google-web-toolkit.googlecode.com; transliterated into Java source

and also came across

Protocol BuffersNew BSD License
code.google.com/p/protobuf

How does this impact Commercial Software development? Both these
licenses are not acceptable to our company and was wondering whether
it would impact developing the software in GWT...

Thanks for your help in advance

Intercept basic authentication popup

[Vinicius Carvalho]

Hi there!

Is it possible to intercept the basic auth login that pops up on a
browser? My problem is that I have a basic auth set on server side for
all my services (RPC and REST).

When I try to invoke a service and the user is not authenticated,
before I get the chance (the async callback gets called), the window
pops up.

What I would like (I know i could do this using either form, or spring
security for instance) is to intercept the return from the server that
asks for the authorization credentials, and then provide my
credentials on the requestbuilder by setting username/password.

Is this possible?

Can't you go to Run Configurations (to configure hosted mode) and set
more memory as a VM argument?  Well that assumes you use Eclipse.  I
have -Xmx512m and it never has a problem.

If that doesn't work, I'd try setting a  VM argument under Advanced
when you click to compile the project.  I"m not sure if the settings
get carried over to developer mode though, so that's why I'd set it
directly first.

Re: Wave rich text editor

[Thomas Broyer]

Your bug report  actually 
had answers… on the wave-dev mailing list!
See 
http://mail-archives.apache.org/mod_mbox/incubator-wave-dev/201106.mbox/%3cbanlktinwsi4mpu3dgwvqpvhxr4kmz0nzr0eiqzwch9zdimx...@mail.gmail.com%3E
 (also, 
read the associated thread)

If you want to reuse the Editor though, the module you actually need is 
org.waveprotocol.wave.client.editor.Editor. And you'll probably also need 
org.waveprotocol.wave.model.Model (and 
org.waveprotocol.wave.model.account.Account and 
org.waveprotocol.wave.model.supplement.Supplement or you'll have a bunch of 
errors on the console; it won't make you build fail though, unless you build 
in -strict mode)
EditorHarness is, as its name suggest, the GWT *application* that allows 
devs to test the Editor. It's a good start to understand how to bootstrap 
the editor, but it's not a reusable module.

RequestFactory causing OutOfMemoryError

[Filip Krygowski]

Hi!

We've recently been trying to switch from GWT-RPC to RequestFactory
and we've been generally successful. However, we’ve noticed that after
quite a large number of requests (depending on the volume of data
sent) the server was running out of memory. I set up a test project to
investigate and came up with this simple class:

public class SampleMessage {
private String message;
private List numbers;

// getters and setters cut for brevity
}

and a client-side ValueProxy for it. Regardless of the size of the
data sent per request (controlled by the number of  Longs in the
list), we were still running out of memory, both in development mode
and with compiled code deployed on a server. Later I’ve come across
this issue: http://code.google.com/p/google-web-toolkit/issues/detail?id=6193
; thinking it might be related, I checked out the GWT trunk, built the
jars and used those, but that didn’t help.

I took a long and careful look at the heap and after some analysis I
noticed that the Longs I’ve been sending don’t get garbage-collected
(also true for other types stored in lists, which I checked later).
The same goes for all serialized properties (the ‘message’ String and
Longs). The questions at this point is: is this some kind of caching
feature that backfires on us? Or is it possible that we messed up
configuration at some point? Or perhaps this is a new bug?

Thanks in advance for all replies,
Filip Krygowski
