This just took me a really long time to figure out, so I’m writing it down. Tapestry 5.1 adds support for submit buttons with an image (I think it was added in 5.1). In any case, you just use the normal tag, but you add an image attribute which is an “asset”. I added an Asset property to my page class and used @Inject and @Path to inject the asset. I used that property name in the image attribute, and it didn’t work. It turns out, you don’t need to declare the asset as a property in your page class. You just specify the path in the image attribute just like you would in the @Path annotation. So, it looks something like this:

<t:submit image=”context:images/submit.gif”/>

Much simpler than I was thinking. Sometimes I get really frustrated with these little Tapestry issues…
