Re: GWT 2.8.0 compile warnings

[Dave Kichler]

Scoured my classpath for any conflicting dependencies and found none.  Also 
cleared out my gwt-unitCache but no to avail - the warnings still remain.

Re: GWT 2.8 generates code 14% bigger than GWT 2.7

@Jens

I've tried WITHOUT any success to use closure compiler externally with GWT 
2.8
See my question 
here: 
https://groups.google.com/forum/#!searchin/google-web-toolkit/closure$20compiler%7Csort:date/google-web-toolkit/k_kjIv9Klsg/LZAZiUf9BAAJ
Still want to find out exact steps to get it working :-(

Re: Bug in IE11 with GWT project (White screen after some time)

[Slava Pankov]

I'm using jQuery Datatable and GWT 2.8, and don't have any problems with 
IE11, despite of large (thousands of rows) datasets fetched from the server 
side.
It could be many reasons why your app is failing, try to open web 
development tools, may be something will be logged there during your app 
crash.

Bug in IE11 with GWT project (White screen after some time)

[johan . diringer]

Our team has a problem when running a GWT application on IE11. After some 
time, the content of the IE11 browser becomes white.
One of the characteristic of the problem is that this happens randomly, 
sometimes after 1.5 hours, sometimes a complete night, sometimes more (one 
of the requirement of the application is to keep it opened several days).







- GWT 2.8 version (bug is present with 2.7 version too (tested))
- Datatable (jquery datatable plugin) is in use (via JSNI) but the problem 
occurs with pure GWT as well,
- Application is requesting data to the server every 5 seconds via http GET 
request,
- To reproduce the bug faster I open 5 windows together (same application 
same data), after one night some of them are frozen (i.e. blank page) 
(mainly 2), some of them are still working,
- I am using local network,
- The problem does not occur with firefox version 45.4.0 (application for 
IE11 is compiled with the same user.agent property gecko1_8),

My question is:
Has anybody else already seen this strange behavior?
Has anyone any idea what I could try?
I already tried with enabling/disabling the "Use software rendering instead 
of GPU rendering*", I already tried with disabling all add-ons.

Thank you.

gwt compile error "No source code" using gwt-lib with transient sources

[Michael Budnick]

My current maven project (named refBuecherWelt) is based on 3 submodule 
(shared,server,client) layout from the gwt-maven-archetypes [1].
The refBuecherWelt-client submodule (a gwt-app) depend on an other lib 
(named universalclientLib) which is build in an independend maven project.

When I migrate the lib also to 3 submodules, gwt:compile (or 
gwt:codeserver) shows the error
[INFO]   [ERROR] Errors in 'de/all4net/.../client/FaceDataObject.java'
[INFO]  [ERROR] Line 8: No source code is available for type 
de.all4net...shared.TaskDirection; did you forget to inherit a required 
module?

The lib-client is a gwt-lib and depend on jars lib-shared and lib-shared 
with sources but the gwt-comiler don't see the sources from lib-shared.

How must I reference the lib-shared so the gwt-comiler see the sources if 
compiling the refBuecherWelt-client?

Re: GWT 2.8 generates code 14% bigger than GWT 2.7

[Kirill Prazdnikov]

Hi Jens,

What if we have SSO linker ?
Then no hacks is needed, right ?
Then just run the Google Closure Compiler on the output.

Thanks for your help, but unfortunately this does not look like a simple
process to implement for GWT users like us.  For the moment we will remain
in GWT 2.7 which generates a smaller code for our website, and hoping that
future GWT versions will be able to reduce or at least maintain the same
code size as version 2.7

Basically you would need to replicate what has been done programmatically 
in the removed ClosureJsRunner class. See commit

https://github.com/gwtproject/gwt/commit/162ccc9c9112a09bf9ea046da95760f5f1886b72

Looks like you have to
- define your own gwt_externs file to tell Closure Compiler which special 
GWT variables not to rename
- maybe create a hack.js file that exports gwtOnLoad function so it does 
not get removed by Closure Compiler. Maybe its not needed if also passing 
in the .nocache.js file to Closure compiler. no idea.
- Give Closure Compiler the GWT output (your *.cache.js files including 
split points) in the correct ordering as split point files have 
dependencies (initial fragment, leftover, split points)

Do you have a step by step guide to run the closure compiler externally ?
