Any Help is greatly appreciated. I copy and pasted the code off of the tutorial (http://www.playframework.org/documentation/2.0.2/JavaTodoList) I'm not sure what's going wrong and I'd really like to learn this technology!
Apparently you didn't import Task model into your Application controller
You have 3 solutions:
Import each model manually:
import models.Task;
import exactly all models into your controller (it will be the best at the beginning, but...)
import models.*
Most recommended: Use some IDE which knows when and how to import required packages and classes and suggest you what should be imported (or not) (ie. IntelliJ Idea - just suggestion)
I got the same problem (error: cannot find symbol), sure that I have
import models.*;
but the error is still there.
I'm using eclipse 4.2, and it just suggest create new method form(Class<Task>

I'm quite new to gauge and have problems running a set of gauge tests. When I try to gauge run I get the following console output:

This is the error i am seeing when i add "simple_permissions" package. How can i fix this? I recently upgraded flutter and it used to work very well before the upgrade.

The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.
[!] Flutter tried to create the file `android/settings_aar.gradle`, but failed.
To manually update `settings.gradle`, follow these steps:
1. Copy `settings.gradle` as `settings_aar.gradle`
2. Remove the following code from `settings_aar.gradle`:
def localPropertiesFile = new File(rootProject.projectDir, "local.properties")
def properties = new Properties()
assert localPropertiesFile.exists()
localPropertiesFile.withReader("UTF-8") { reader -> properties.load(reader) }
def flutterSdkPath = properties.getProperty("flutter.sdk")
assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
apply from: "$flutterSdkPath/packages/flutter_tools/gradle/app_plugin_loader.gradle"
Exception: Please create the file and run this command again.
Exited (sigterm)
I suggest you to check the package before using it.
It seems that simple_permissions is outdated and this package hasn't been updated since 2018 and its repository is gone from github, consider using other package like permission_handler.
Cheers.
I am working with JOGL and it stopped working completely.
These are the errors i get:

The Path and Classpath variables are correct, I reinstalled JDK and JOGL2 but still get an error with WriteClonable and com.jogamp.common.nio.*
Any help is appreciated!
Is it possible to reference a UiBinder created widget and pass is to a setter of other widget in *.ui.xml file?
I've tried following code to create a label (CustomLabel) that can listen to and follow the state of form widget (CustomWidget). The problem is that GWT compilation fails with:

View.ui.xml:
<g:HTMLPanel>
<x:CustomLabel forTarget={widget} />
<x:CustomWidget ui:field="widget" />
</g:HTMLPanel>
View.java:
#UiField
CustomWidget widget;
CustomLabel.java:
public void setForTarged(CustomWidget forTarget) {
this.forTarget = forTarget
}
In principle this should work. I use similar references in my code.
In your View.java:
#UiField
CustomWidget customWidget;
should be
#UiField
CustomWidget widget;
No, you cannot do it this way - no widget is available yet when your setForTarget method is called by UiBinder.
You can call this method in your code after your custom widget has been initialized.

Seems like you are missing the commons-math3 library.
