I'm interested in the possibility of developing Liferay portlets on Grails, using the Grails Portlets plugin. I reckon introducing a portlet framework (such as the Spring Portlet API) will make development faster and more comfortable, so being able to further add Groovy and Grails conventions to the mix sounds almost too good to be true.
I guess this combo is relatively new, since this far I've found no experiences on how well this works in practice, or of its potential pitfalls.
Any experiences, suggestions or warnings? I would greatly appreciate them.
