Super Dev Mode stopped working in Chrome

[N Troncoso]

Super Dev Mode is no longer working for me in Chrome. It used to give me 
the little shield in the address bar that let me accept mixed content. That 
got annoying, so I added the "--allow-running-insecure-content" parameter 
and it didn't make me go through that anymore.

Now, in Chrome 55, the shield looks different, and even when I click *Load 
Unsafe Scripts*, I get an error in the console like this:

"Mixed Content: The page at 'https://localhost:8443/weboffice/' was loaded 
over HTTPS, but requested an insecure script 
'http://localhost:9876/Home/FFC7A6090089FC6C17C3AE41F1F2F628.cache.js'. 
This request has been blocked; the content must be served over HTTPS."

The only thing I found so far is to add the parameter 
"--disable-web-security", but that didn't work.

Does anyone have a work around for this issue? I am using SSL.

Re: GSS changes aren't recognized in SDM

[N Troncoso]

Oh. I didn't know that was needed. It's a little inconvenient, but it's 
better than restarting the code server. Thanks!

GSS changes aren't recognized in SDM

[N Troncoso]

I'm starting a new project using GWT 2.8-rc2, and am setting up my GSS 
resources. It all works and the pages render correctly, but if I change a 
GSS file, the changes aren't loading when I refresh the browser.

I have my ResourceBundles in 
*src/main/java/com/company/project/client/resources*

And I have my gss files in 
*src/main/resources/com/company/project/client/resources/gss*

So, when setting up my ResourceBundle, I do *@Source("gss/style.gss")*

Just in case this is relevant, here are the properties in my gwt.xml file 
for GSS:




This works, but like I said, if I make a change in style.gss, the change is 
not loaded when refreshing the browser. I have to stop the codeserver and 
restart it

I don't think this matters, but the way I set up my resources is to have a 
CssResource per gss file. Then, I have a singleton Resource.java class. In 
it, I have a single ClientBundle that hooks each CssResource to its gss 
file. Then, I create static methods for each Resource. It looks like this:

public class Resources
{
public static interface ResourceBundle extends ClientBundle
{
@Source("gss/flex.gss")
FlexStyleResource flex();

@Source("gss/colors.gss")
ColorResource col();

@Source("gss/fonts.gss")
FontResource font();

@Source("gss/widgets.gss")
WidgetResource widget();
}

private static Resources INSTANCE;

public synchronized static Resources get()
{
if (INSTANCE == null)
{
INSTANCE = new Resources();
}

return INSTANCE;
}

public static FlexStyleResource flex()
{
return get().resources.flex();
}

public static ColorResource col()
{
return get().resources.col();
}

public static FontResource font()
{
return get().resources.font();
}

public static WidgetResource widget()
{
return get().resources.widget();
}

private final ResourceBundle resources;

public Resources()
{
resources = GWT.create(ResourceBundle.class);
}

public void init()
{
resources.flex().ensureInjected();
resources.col().ensureInjected();
resources.widget().ensureInjected();
resources.font().ensureInjected();
}
}

And so, when I need something, I can do *Resources.col().primaryColor()* for 
example. *Note*: I call init() in my EntryPoint.onModuleLoad()

Thanks in advance for any advice

Ui Binder Alternatives

[N Troncoso]

With GWT 3.0, Widgets and UI Binder is losing support. Even besides that, 
I'm not a huge fan of UI Binder. I'd really just prefer to use vanilla 
HTML. With that said, I've been searching for other options and I've only 
found that alternatives are very limited. Even more so, examples of how to 
integrate alternatives into GWT are basically non-existent. So, my question 
is, what can I use instead of Widgets and UI Binder and where can I find 
examples/tutorials/documentation on how to use them in GWT.

I found Errai  as one option. But, this seems 
to be an entire framework, rather than just a template system.

Any insight would be greatly appreciated. Thanks

Re: Maven Plugin for GWT - Access Dev Mode Remotely

[N Troncoso]

I'm using the net.ltgt.gwt.maven.gwt-maven-plugin. I didn't know the 
bindAddress was strickly for the mojo plugin. From what I can tell it's a 
fairly common parameter for opening something to a network.

I'm not sure what config you're asking about, but this is how the plugin is 
setup in the pom file:


net.ltgt.gwt.maven
gwt-maven-plugin

path.to.Home
Home



When working locally, I use https://localhost:8443 to hit dev mode and that 
works fine. From remote, I'm using https://:8443. Here's the 
message I'm getting:

<http://i.imgur.com/6Q468cM.png>

Like I said before. This is normal on the local machine. I just disable the 
security from the browser and it works. But it does not in this case.

I think that answered all your questions.

Maven Plugin for GWT - Access Dev Mode Remotely

[N Troncoso]

I need to be able to hit my dev mode machine remotely. I'm using the Maven 
Plugin for GWT (tbroyer version). The standard commands don't let you hit 
the remote machine at all.

If I add -Dgwt.bindAddress=0.0.0.0 to the code server command:

call mvn gwt:codeserver -pl client -am -Dgwt.bindAddress=0.0.0.0

I can hit it remotely, but I get a dialog that says "Can't find code 
server. Please make sure it's ready". I don't know what to do to get past 
that.
On the same machine, that just means the browser is blocking insecure 
content. Clicking the shield in the address bar (left in FF, right in 
Chrome) let's you disable this.
I did this on the remote machine, but it still fails to load.

Any help would be great. For reference, I'm starting tomcat like this:

call mvn tomcat7:run -pl server -am -Denv=dev

GWT, Firefox, and focusout

[N Troncoso]

I have an issue where an event isn't firing in Firefox, and it turns out 
this is because Firefox doesn't currently support the focusin and focusout 
events.

This is a problem in a custom cell where I'm overriding onBrowserEvent. On 
the blur event, the ValueUpdater parameter is null, but it's not null on 
the focusout event. How can I work around this issue?

Cell Table keyboard navigation doesn't work in Firefox

[N Troncoso]

The CellTable has a keyboard mode to allow moving around with arrow keys. 
In Chrome, when moving to an input cell, the cell content is selected 
(hightlighted), but you can still moving to other cells until you start 
typeing.

In Firefox, the cell content does not highlight. You have to press enter to 
start typing.

Is this a known issue? Does anyone know of a work around?

Re: Are there any currently developed GWT Widget Libraries?

[N Troncoso]

 I started using GWT Polymer for my Web App a few weeks ago. I had to get 
over some difficult hurdles, but I think it's really paying off. The UI is 
sleek and responsive and just overall works very well. 

It's more or less the same as GWT Material from what I can tell (they are 
both designed around Google's Material spec). GWT Polymer is really just a 
wrapper, though, for their javascript library, so it requires jsInterop.

GWT Plugin for Maven with Polymer (jsinterop)

[N Troncoso]

Switching to the Maven Plugin for GWT 
, I'm unable to get GWT to 
recognize the jsinterop flag. I'm assuming not many people using this 
plugin are using jsinterop, because I can only find a single source about 
it: https://github.com/tbroyer/gwt-maven-plugin/issues/22

In which there is no answer. I've tried putting:


-XjsInteropMode
JS


-XjsInteropMode
JS


in the parent pom under the gwt-maven-plugin configuration, as well as in 
the client, as well as both. Since I'm using GWT 2.8, I've also tried the 
-generateJsInteropExports 
flag. When I try to run the application, I get:



In the codeserver logs, I see:

 Arguments: com.google.gwt.dev.codeserver.CodeServer -logLevel DEBUG 
-workDir \target\gwt\codeserver -sourceLevel 1.8 -failOnError 
-launcherDir \target\gwt\launcherDir -XjsInteropMode JS 
-allowMissingSrc -src \client\src\main\java -src 
\shared\src\main\java com.ecrsoft.supportnet.Main

 The experimental -XjsInteropMode option is deprecated and will be removed 
very soon. See https://goo.gl/uMdOQS for migration instructions.

Which tells me the flag is being recognized.

I see lines like this that make me think it's getting compiled:

[INFO] Resolving annotation for jsinterop.annotations.JsMethod
[INFO]  Resolving method $isInstance
[INFO] Resolving annotation for jsinterop.annotations.JsMethod


But it still gives me that error. I've been looking at this for several 
days. Turning on jsinterop with mojo's plugin works fine, so I have to 
determine that the issue is with this plugin. That issue I link above was 
closed back in April. Has no one at all seriously tried using this plugin 
with polymer since then? I'm only using jsinterop for Polymer, so I don't 
have any existing annotations or anything. I'm very open to suggestions. 
Thanks.

Re: GWT Plugin for Maven with Polymer (jsinterop)

[N Troncoso]

Thanks for that. Nothing you said was the issue, but it prompted me to 
double check my GWT version. It turns out I was using 2.8 beta instead of 
SNAPSHOT. I guess your plugin doesn't work with beta? Before switching, I 
was using beta for my gwt version and snapshot for my mojo plugin version 
and everything was good. Granted, maybe the -XjsInteropMode flag was 
removed in beta, which would explain the issue. I didn't think it'd be 
removed until release.

getSession().getServletContext().getRealPath returns wrong path

[N Troncoso]

I restructured a project to use tbroyer's gwt maven plugin and split the 
code into client/shared/server modules. Since then, 
getSEssion().getServletContext().getRealPath("/") is returning 
Project\server\src\main\webapp\, when it should be returning the target 
directory. Is there something in that plugin that affects this, or is there 
a setting I can check to fix this?

I am. The problem I'm getting is that I'm trying to get the path to a file,

trying to find something in /resources (target) vs.

GWT Maven plugin can't find shared source

[N Troncoso]

I migrated a maven-gwt-plugin project to "Maven Plugin for GWT" 
(https://tbroyer.github.io/gwt-maven-plugin/). To do this, I generated a 
new project with the archetype provided. Upon simply running that 
application, it worked fine.

Then I copied client files to the client, server to server, and shared to 
shared. After getting everything sorted out and attempting to run the 
codeserver, I get a bunch of:

[ERROR] Line 65: No source code is available for type com.some.package.
shared.AClass; did you forget to inherit a required module?

I ran the codeserver via *mvn gwt:codeserver -pl client -am* and I tried *mvn 
gwt:codeserver -pl client,shared -am* to see if that would help.

These are my client shared dependencies (not changed from the default 
project):

Re: Layout principles for UIBinder with Polymer elements

[N Troncoso]

The DockLayoutPanel is designed to take up the whole screen. You only have 
to define the size of the north/south/east/west panels (or don't give them 
a size for them to not appear). The center takes up the rest of the 
available space.

As for Polymer, look at the catalog for the elements you want to style. 
Here is paper-button for 
example: https://elements.polymer-project.org/elements/paper-button

Re: Using MVP with GWT2.7

[N Troncoso]

You could technically do that, but you'd need some way to differentiate 
between events; Maybe with an enum:

public class MyEvent extends GwtEvent
{
public static enum EventTypes
{
THIS_EVENT,
THAT_EVENT;
};

public interface Handler extends EventHandler
{
void onDispatch(MyEvent event);
}

public static final GwtEvent.Type TYPE = new 
GwtEvent.Type<>(); // NOSONAR

private final EventTypes type;
public MyEvent(EventTypes type)
{
this.type = type;
}

@Override
public GwtEvent.Type getAssociatedType()
{
return TYPE;
}

public EventTypes getType()
{
return type;
}

@Override
protected void dispatch(Handler handler)
{
handler.onDispatch(this);
}
}

I don't think this is a very good approach, though, as you lose the ability 
to pass specific parameters based on that particular kind of event.

Re: GWT maven plugin can't find shared sources (take 2)

[N Troncoso]

After looking more carefully, I'm only getting this for 1 class:

[ERROR] Line 65: No source code is available for type com.
path.to.shared.i18n.PhxMessages; did you forget to inherit a required module
?

I get that a whole bunch of times (cause it's referenced many times).

Then after that, I get:

[ERROR] 109 com.path.to.shared.data.entity.impl.Employee cannot be resolved 
to a type

for pretty much every other class in my shared module.

So it sees PhxMessages and just doesn't have the source code, but it can't 
find Employee at all? I'm not sure what to make of that.

Juan is correct. If you populate the list in the start() method of the

Re: GSS eval not evaluating

[N Troncoso]

While I'd still like to know why this isn't working, I worked around the 
issue by creating constants:

public interface ColorResources extends CssResource
{
public static String shadowZ0  = Util.getShadow(0);

public static String shadowZ1  = Util.getShadow(1);
public static String shadowZ2  = Util.getShadow(2);
public static String shadowZ3  = Util.getShadow(3);
public static String shadowZ4  = Util.getShadow(4);
}

with this, I can skip the GSS constants altogether

GSS eval not evaluating

[N Troncoso]

I have a method that calculates a box shadow. To use it, I call 
getShadow(int depth). If I call this, I get the expected result. Now, I'd 
like to create a few predefined constants in GSS. So, I do this:

public interface ColorResources extends CssResource
{
String shadowZ0();
String shadowZ1();
String shadowZ2();
String shadowZ3();
String shadowZ4();
String shadowZ5();

public static class Util
{
private Util() {}


public static String getShadow(int dp)
{
return shadow;
}

public static String shadowZ0()  { return getShadow(0); }
public static String shadowZ1()  { return getShadow(1); }
public static String shadowZ2()  { return getShadow(2); }
public static String shadowZ3()  { return getShadow(3); }
public static String shadowZ4()  { return getShadow(4); }
public static String shadowZ5()  { return getShadow(5); }
}
}


colors.gss:

@def SHADOW_Z0 eval('path.to.ColorResources.Util.shadowZ0()');
@def SHADOW_Z1 eval('path.to.ColorResources.Util.shadowZ1()');
@def SHADOW_Z2 eval('path.to.ColorResources.Util.shadowZ2()');
@def SHADOW_Z3 eval('path.to.ColorResources.Util.shadowZ3()');
@def SHADOW_Z4 eval('path.to.ColorResources.Util.shadowZ4()');
@def SHADOW_Z5 eval('path.to.ColorResources.Util.shadowZ5()');


But if I do GWT.log(Resources.colors().shadowZ0()) (Where Resources is my 
ClientBundle that ColorResources is in), the print value is:

"Java expression : path.to.ColorResources.Util.shadowZ0()"

It should be evaluating the expression, not just returning it anyone 
know what's up?

Re: Getting rid of Dev mode for future GWT releases

Can you like explain a little more about your setup? In our production

There are some discrepancies there, and any Tomcat specific issues are 
super hard to debug. We've been trying to move to SDM with Tomcat, but we 
haven't gotten it working. Is there any special setup involved?

Re: How to register custom function with GSS

That's a shame. Though, I may be able to do what I need with a mixin, but 
the conditionals don't seem to support '='??

Is this valid? :

@defmixin shadow(SHOW)
{
@if (SHOW = 1)
{
box-shadow: 0 1px 1px rgba(0, 0, 0, .24), 0px 1px 1.5px rgba(0, 0, 
0, .12);
}
@else if (SHOW = 2)
{
box-shadow: 0 10px 5px rgba(0, 0, 0, .22), 0px 14px 14px rgba(0, 0, 
0, .25);
}
@else
{
box-shadow: none;
}
}

I also tried @if (is("SHOW = 1")), but that didn't work.

Re: Understanding the Layout System

[N Troncoso]

I have content that goes under the TabPanel. (a StackLayoutPanel actually), 
so a scroll bar inside does not solve an issue like that. 

My question isn't necessarily aimed to solve that particular problem, but 
to understand the way the LayoutPanels are suppose to be used to create an 
app. The very basic examples that the documentation provides, and the fix 
you provided here does not really translate into how you'd develop an 
entire web app using these techniques. Am I only suppose to use 
LayoutPanels when I want to fill the screen and have no overflow? Am I 
stuck using the old bunch-o-tables widgets (or writing my own) otherwise? 
Supposedly these old widgets don't play well in standards mode, so it'd be 
nice to get away from them.

I guess your FlexBox suggestion at least solves the issue of building a 
proper layout, but if I forgo LayoutPanels altogether, I'm stuck with the 
"bad" old widgets and panels. Granted, I don't suppose I have to be 100% 
reliant on GWT to hand-feed me everything I need. It just feels like I'm 
missing critical components of the LayoutPanel that would allow it to work 
the way I want.

Re: Understanding the Layout System

[N Troncoso]

I have content that goes under the TabPanel. (a StackLayoutPanel actually), 
so a scroll bar inside does not solve an issue like that. 

My question isn't necessarily aimed to solve that particular problem, but 
to understand the way the LayoutPanels are suppose to be used to create an 
app. The very basic examples that the documentation provides, and the fix 
you provided here does not really translate into how you'd develop an 
entire web app using these techniques. Am I only suppose to use 
LayoutPanels when I want to fill the screen and have no overflow? Am I 
stuck using the old bunch-o-tables widgets (or writing my own) otherwise? 
Supposedly these old widgets don't play well in standards mode, so it'd be 
nice to get away from them.

I guess your FlexBox suggestion at least solves the issue of building a 
proper layout, but if I forgo LayoutPanels altogether, I'm stuck with the 
"bad" old widgets and panels. Granted, I don't suppose I have to be 100% 
reliant on GWT to hand-feed me everything I need. It just feels like I'm 
missing critical components of the LayoutPanel that would allow it to work 
the way I want.

Understanding the Layout System

[N Troncoso]

I've been reading a lot about the LayoutPanels introduced in 2.0 and trying 
to understand their purpose. I keep seeing that I should be using these 
instead of the older panels, but they seem way more complicated and 
limiting.

Take my app, for example. It's got a straight forward interface: A fixed 
header, fixed menu on the left, and a fixed footer. The remaining space is 
the content of unknown size.

For this, I use a DockLayoutPanel, and it works well. What does not work 
well is the content part. It makes complete sense to use a ScrollPanel here 
(right?), to accommodate any amount of content. And of course, that breaks 
the ProvidesResize/RequiresResize chain (although the ScrollPanel does 
indeed implement both of those methods...).

So anyway. I want to use the TabLayoutPanel in place of the TabPanel I am 
currently using, as that's the recommendation, but I can't. It won't show 
because it's not getting sized. So what can I do? Give it a static size or 
put it in a ResizeLayoutPanel to handle the resizing, which isn't much 
better as I still have to specify the size. I don't know how big the 
content of the tab panel will be, so that's just not an option.

>From what I read, these panels do not work with dynamic sized content.

So what's the deal here? I can see the RootLayoutPanel and DockLayoutPanel 
being used to set up the basic layout of the app. But what of the rest of 
these panels like the TabLayoutPanel and StackLayoutPanel? Unless I'm using 
these as the ground work for an entire app, they seem useless. I'd like to 
use them as they build their underlying DOM elements with divs instead of a 
bunch of nested tables, but I guess that's not an option? 

Am I missing something? Am I still suppose to be using the old panels for 
everything but the base layout of the app? Or is there some sort of new way 
of building web apps that doesn't require dynamically sized content that I 
haven't heard about?

I feel like a bunch of this old stuff will be deprecated soon in favor of 
the LayoutPanels, but where does that leave me when it doesn't work for 
what I need?

Thanks for any advice.
