ZK 5.0.11 After setting value on a widget via 'w:onClick', how does one make the widget to send its value to the component, so that it can be used in a composer?

Hello,

I have w:onClick on a button which executes a custom javascript and sets value of a different widget:

i.e. this.$f('is123').setValue( javascript_computation );

After the javascript finishes and I inspect the value of 'id123' in a composer, the value is unchanged.

In version 3.6.5, I used comm.sendEvent, however that is unavailable in version 5.

Thanks for your help.

Hello abcd123,

The solution to your problem is that you have to fire an event to the widget. For more information please look at the following url's:

How one would do that when changing a label value ? I added an event listener on the widget for a textarea in a custom component

textArea.setWidgetListener(Events.ON_CHANGING, "this.nextSibling.firstChild.setValue(event.data.value.length)");

To update a label with a counter. But on the server side, the value of the counter is never updated. And I've a button which call the server and , among other things, clear the textarea of the component, and thus I want to reset the counter label to 0 but since server side it's still 0 it nevers updated the value on the front ...

The idea was to use a front side listener to avoid adding the listener on java side ... and maybe avoid calling the server on each onChanging of the textarea.
