The July edition of GroovyMag is out! There's a lot of great articles in it including the one I authored entitled 'Inline Editing with jQuery'. The goal of the article is to teach the user how to create an inline editable datatable which supports editing with textfields, textareas, select lists, and datepickers. On top of all that is sprinkled a healthy dose of ajaxy goodness.

Transaction handling is one of the more complex areas of web development. Anytime a user takes any action in the interface which demands a couple of database actions in the backend, then usually you end up having do it as transaction. For a user, everything is either a success or failure. Partial success may be either harmful to the system or doesn’t mean anything to the user. Grails, since it is built on top of Spring and Hibernate, uses their underlying mechanism to deal with transactions. While it may seem confusing in the beginning, Grails actually makes it even more easier.
