One-way data binding for Polymer templates

New features

• PolymerTemplate now supports a server-side model. Values from the model can be used in regular one-way [[binding]] definitions in the template.
  • Advanced features such as sub items, lists and two-way bindings are still missing.
• Existing client-side polymer event handlers are now run even if there's a server-side @EventHandler with the same name.

Fixes

• Setting innerHTML of an element explicitly detaches all children.
• Setting outerHTML of an element explicitly forbidden.
• Requests for favicon.ico are not handled by Router.
• Picked fixes from Framework v7 and v8.

Demos

• There's a README.md.
• Polymer minesweeper has been updated to use PolymerTemplate instead of only using low-level Element features. (Still only works in Chrome.)

Tutorials

• New Hello World tutorial for Polymer templates.
• New tutorial about using <slot> in Polymer templates
• New tutorial about @EventHandler and @EventData in Polymer templates.

Loading performance improvements

New features

Breaking changes

All imports done via annotations (@JavaScript, @HtmlImport and @StyleSheet) are now imported with no specific order.
This means that HTML imports are now loaded disregarding the JavaScript imports order.
If you want to have a specific import order, please specify it in on of the HTML imports.

JavaScript Integration helpers

New features

• Provide $element to template event handlers
  • (click)="$server.clickOnText($element.textContent)

Bean import filters

New features

• When importing a bean to the template model, you can define that some of the bean properties should be excluded from the model
  • The same annotations are also supported on list setters, where they will apply to each item in the imported list.

public interface MyModel extends TemplateModel {
  @Exclude("id", "password") // includes all other properties
  public void setUser(User user);

  @Include("firstName", "lastName") // excludes all other properties
  public void setPerson(Person person)
}

• View instance creation is pluggable to enable integration with e.g. Spring or CDI
• Client side exception messages are shown as a floating overlay in the browser when production mode is not active
