tapestry template called twice for each request

I'm running a tomcat 8/spring 5.4.1/Tapestry 5.4.1 setup. I have a simple template with a component for layout. The template calls a spring service that gets the count of people. Simple. What's odd is that the Index template is being loaded twice and it seems that it's due to the t:type="layout" tag in the index.tml page which references the layout component. If I remove this, it's called only once.

This is the log from tomcat clearly showing that index is called twice.

May be you are trying to return HomePage after Hibernate call is executed. If you observe after Hibernate call execution your page is again loading
