I am using Tiles and validation framework. In my design I am implementing a page where users can type a query to get some results in a different page (tile). At the beginning the page display just fine, but after submitting the query I am getting tag useAttribute : no tiles context found if the page gets validated.
I had disabled the validation clause to the page and I do not get the error. My idea is that validation framework is causing the problem. Some how, when the page gets submitted it losses the context information . Here you have some code so you can have a better understanding.
