Hello,

I have a form where a file is uploaded to the server, and It is required that while the file is loading the page is blocked with an overlay, i'd like to know how to achive this, i haven't seen that option in the docs and I've looked to the source code for uploading files (guess it's this one: //github.com/zkoss/zk/blob/884e074c3ab999798dcf38b01564ec1f4c940818/zul/src/archive/web/js/zul/Upload.js#L380) and as far as i can see in it, on line 380 it just launches the upload and queries the server for when it is finished. Is there any way to achive this?

Thanks in advance

Hello vilcayp,

You can use Clients.showBusy in order to accomplish your task as shown below:

@Darksu, Actually not, i do not want to show the busy indicator when the page is loading, but when it uploads a file. Here (//zkfiddle.org/sample/17oh8i5/2-basic-upload-button) you can see that it works when a file is uploaded, but if the user cancels the file chooser prompt, the busyIndicator does not go (since there is no event attached).
