Hi All, We are trying to fine tune the DAO layer where we are using Hibernate as our ORM. Since we have too many detached objects, every time we go and save which is quite often (because of implicit save) too many queries get fired and the application responds slowly. This happens even if nothing is changed by the user on the UI.
I was hoping to find a dirty flag setter in JSF where it can be checked first and only if the form has been changed will the call to other layers is made. There are a couple of options that we considered: 1. Using JS we iterate all the elements on the page and check if something has changed. However the JS gives an error if there are just too many elements on the page. Most of our pages are long and complex - don't ask me why - just a client requirement :( 2. Attach value change listeners for every component that can be modified. What if nothing gets changed and therefore no ValueChangeEvent is queued. How will this be checked? 3. Hack model update phase and try and set a dirty flag if anything is updated during that phase. Do not know how to do that either? The solution needs to be light on performance. Any pointer would be really appreciated.
