Subject Re: Seeking help for a HotSwapAgent's Wicket plugin
Date Mon, 16 Jul 2018 15:53:21 GMT
Hi Francesco,

Do you have the appropriate Wicket settings enabled?

I'm using this configuration in development mode:

private static void initResourceSettings(WebApplication app) {
> final ResourceSettings resourceSettings = app.getResourceSettings();
> if (!isDeployment(app)) {
> resourceSettings.setDefaultCacheDuration(Duration.seconds(0));
> resourceSettings.setResourcePollFrequency(Duration.seconds(5));
> }
> }


Best,

Thomas
