It should be possible to create a SafeHtmlResource, that could validate the content of the resource at build-time.

Otherwise, your solution below is the only one I could think about.

 

interface TextsBundle extends ClientBundle { @Source("text.txt") TextResource myText(); }

class SafeHtmlTexts {
  @Inject TextBundle texts;
  public SafeHtml myText() { return SafeHtmlUtils.fromSafeConstant(texts.myText().getText()); }
}

class ViewImpl {
  private final SafeHtmlTexts texts;
  @Inject public ViewImpl(..., SafeHtmlTexts texts) { this.texts = texts; ... }
  ...
  @UiFactory SafeHtmlTexts create() { return texts; }

You could simply use a @UiField for 'texts' rather than the @UiFactory. If you want the SafeHtmlTexts to be provided (by GIN apparently), use @UiField(provided=true) (and you can then have your field 'final').

 

}

ViewImpl.ui.xml:
  <ui:with field='texts' type='....SafeHtmlTexts'/>
  ...
  <div><ui:safehtml from="{texts.myText}"/></div>
