Re: Error in superdev mode

[Nagin Kothari]

Strange thing I observed is - Some screens/pages are working well in
suerdev mode while some throws serialization error. I have 5 RPC
services(Remote services). Out of this fine for one remote service .rpc
file generated in dev mode  is named differently  than .rpc file generated
by superdev mode. Screens/pages using this service is throwing error. while
other screens using other four  remote services are working well. Can
anybody (Thomas ? )suggest what could be reason for strange behavior.

Thanks

Re: Error in superdev mode

[Nagin Kothari]

SuperDev Code server create cache.js and .rpc file in temp folder of system
under folder name like this "gwt-codeserver-7917955539027953667.tmp". I see
that rpc file generated in this folder is different than what is complied
by
GWT compiler in war folder of project(which is used by GWT's inbuilt JETTY
server). This could be reason for this error. But I am not able to
understand why this difference and what should be done to avoid this.

I am not using external server for superdev mode. I am using GWT's inbuilt
Jetty server. I was working earlier with chrome 27

Error in superdev mode

[Nagin Kothari]

My GWT application complied in 2.5.1 works well. But when I run this
application in SuperDev mode. , it shows me error "was not assignable to
'com.google.gwt.user.client.rpc.IsSerializable' and did not have a custom
field serializer." . I have verified that all java classes implement
Serializable . Every thing works great in DEV mode and in compiled mode.
But nothing works in SUPERDEV mode because of this error. I am not able
figure out what is cause of this error. Can anybody please hep me ?

My GWT version is 2.5.1.
Chrome version is  30.0.1599.69 m

Thanks in advance

Re: Call for action: Time to rethink a road-map and more frequent updates for GWT.

[Nagin Kothari]

GWT is the very good framework which gives you flexibility to use their
in-built widgets or functionality as well allow to work on low level API or
customize framework to your need like compiler linker etc.  My company does
100% in GWT and Java. Using only one standard language for both server and
client that works on all browsers is brilliant and unique.

Issue with Custom exception in Production mode

[Nagin Kothari]

I have defined custom exception  extending from Exception class. On server
I throws this custom exception with some message.
My RPC call also has this exception  as part of service call signature. In
development mode when I show this message  in "onFailaure()" method of RPC
call on client,
I see proper message. But in production (after compilation)  , on client I
see 500 error instead of message.

Any idea could be the reason and how to resolve this?

Thanks ,

Re: future of gwt & who use gwt

[Nagin Kothari]

Dart is yet very very young.. .I think it will take more than two years to
gain popularity and acceptance(if at all?), also all browser vendors (like
Microsoft) acceptance.
So why worry right now about Dart?
Any way new client side technologies keep coming every year. If at all Dart
gains popularity in future,I think  Google would provide tool to convert
your GWT (java) code to Dart.

Re: GWT 2.2 Canvas support for IE6 (GWTCanvasImplIE6)

[Nagin Kothari]

gwt-graphics is very simple to use and very good. But one more down side,
there is now no  new development in the project and support seems to have
been withdrawn. I have reported Issue related to IE behavior six month back,
but it has not been looked into.Same thing  with other issues that are
reported in this project.

Re: To smart GWT or not

[Nagin Kothari]

Sanjiv,

I know I am reopening this thread,  not to criticise Smart GWT, but want to
give some feedback.

First of all let me acknowledge that it is very good library with lot of
cool and fantastic features. I experimented with it and liked it and
planning to use it in one of my project.But I have some doubts and questions
, which you I thought you will be best person to answer . Hence this mail.

1. I am using  GWT and want to use some Smart GWT widgets in that
application.But it looks like I have to include lot of Smart client JS file
which size is about 2MB. Client need to download all these JS libs above our
GWT compiled script. this become very huge download for client, Even I want
to use  Smart GWT's grid , I realized that I have to include  almost
everything except few small smart-client JS.So my question is why is so and
what is work around for it?

2.Second, smart-client scripts are not in compressed format (like GWT is).
it is like GWT pretty format. If it is compressed then size of all script
files will be reduced.

3. My third question is - Why smart GWT is not written in GWT so that it can
take advantage of GWT's optimised java script compiler.Smart GWT widget the
can be extended by user to customize it. Right now Smart GWT widgets are
just black box for developer.

Theses are few question I had in mind., Over all features provided by smart
GWT are great.

Thank and regards,

Nagin Kothari

Re: GWT with Hibernate and Oracle

[Nagin Kothari]

Hi,
Can you point to some link that provide sample code or utility to clean the
Hibernate POJO (Hibernate Cleaner class) as you have mentioned in this mail.
It would greately help me too.

Thanks in advance,

Re: i18n default locale fallback

Also GWT compiles for one more permutaion for default locale, which is
