Re: Browser.getWindow().newXMLHttpRequest()

[Ignacio Baca Moreno-Torres]

I have two partial examples, one  to create and send a formdata
programmatically
https://github.com/intendia-oss/autorest/blob/gwt-jsinterop/gwt/src/main/java/com/intendia/gwt/autorest/client/XhrResourceBuilder.java
and other to get the datafile that can be added to a formdata
https://github.com/ibaca/dndfiles-gwt/blob/ceda44a6aa5b3497808a7d33ed7ed40b12cc9027/src/main/java/dndfiles/client/DndFiles.java#L45.
Not sure if this will help you, but... this is all you need to know

Re: Problem with GWT 2.8

[Kevin Langille]

Additional information

Running superdev mode from Intellij failed to show the error, only once our 
product was compiled is the error visible. I tested using log statements to 
show the values of the expressions.

I am testing on Windows 10, Chrome, JDK 1.8.0_111. I also reproduced the 
issue in Firefox, edge and IE11.

Sorry I should have mentioned. I was unable to see it using superdev mode 
in Intellij. Only once compiled did the error show.

Looks like you have a wrong version of 
com.google.gwt.uibinder.rebind.UiBinderWriter on classpath. If you are sure 
you have no GWT 2.7 dependency on classpath anymore then some 3rd party GWT 
library your app is using probably has a copy of that (outdated) class 
bundled.

Help modifying celltable styles with gss

[Raymond Hawkins]

I'm in the process of updating to GWT 2.8, and I have the following code 
from 2.7:
public interface DataGridResource extends DataGrid.Resources {
  public interface Style2 extends Style {}

  @Source({DataGrid.Style.DEFAULT_CSS, "MaterialDataGrid.css"})
  Style2 dataGridStyle();
}

Following the instructions on 
http://www.gwtproject.org/articles/gss_migration.html, I'm trying to switch 
to using all gss. however, when I try to change MaterialDataGrid.css 
to MaterialDataGrid.gss, I get the following error: "[ERROR] Only either 
css files or gss files are supported on one interface".

I assume this is because "You cannot mix css and gss on the same method 
(@Source annotation)." and DataGrid.Style.DEFAULT_CSS points 
to com/google/gwt/user/cellview/client/DataGrid.css. 

If I manually use "com/google/gwt/user/cellview/client/DataGrid.gss", it 
works fine, but there doesn't appear to be a constant for the gss path. Am 
I missing anything here, or should I just either use the full path in my 
code or replace ".css" with ".gss" on DataGrid.Style.DEFAULT_CSS?

Thank you!

Internal GWT 2.8.0 compiler exception

[jgindin]

I'm trying to update my project from GWT 2.7.0 to 2.8.0. However, I'm 
getting the following error during the GWT compilation.

We're using dagger and guava 20. I've validated that:

   - dagger-compiler is *NOT* in the classpath when compiling. (We're using 
   gradle and the "net.ltgt.apt" gradle plugin to use the "apt" configuration 
   (which is where the dagger-compiler dependency is listed).
   - there are no gwt 2.7 artifacts in my classpath

Missing Custom Linker Output Files when using GWT Eclipse Plugin

[bobbitdiddle]

When using the GWT 2.7 Eclipse Plugin and a custom linker, if I create a 
new artifact, foo.js, inside the linker, it doesn't show up when I try to 
load it from the main web page of my application.  I need to create this 
file to dynamically load certain script files.  I already observed that the 
.nocache.js that's served to the browser is different from the one 
that I actually emit in the linker - so this is an attempt to work around 
that.

Is this a known limitation, that any files you create are just thrown away 
and not served back to the application?

Looks like you have corrupted JARs. Try re-downloading them (delete them 
and re-run Maven)
