问题 Is it possible to get filetered data from pipe to component? If our data filtered by pipes in template, How I can grab this filtered data and pass it into my component ? :) Many thanks for any help. 回答1: I don't know if it's a good think and what is your exact use case but you can inject the component instance (or a shared service) into the pipe constructor. Then you can set value on it: @Pipe({ name: 'test' }) export class TestPipe { constructor(@Inject(forwardRef(() => AppComponent))

Then I decided to refactor it in Flux pattern, using Alt and following the guidelines of this tutorial. Everything

问题 I have an ICEfaces web app which contains a component with a property linked to a backing bean variable. In theory, variable value is programmatically modified, and the component sees the change and updates its appearance/properties accordingly. However, it seems that the change in variable isn't "noticed" by the component until the end of the JSF cycle (which, from my basic understanding, is the render response phase). The problem is, I have a long file-copy operation to perform, and I would
