I have very complex model. The flow is like this:
- in controller I populate the model from the database
- in view I have several tabs. After I fill in the info on the first tab, the second tab enables (this works just fine) and on click on the second tab button I need to update some properties of the model. How can I do this WITHOUT calling the database again in order to populate the model on the controller? The model is very complex, so I can't store as "hidden" all the properties.  

I hope I managed to be clear enough. 
Thanks for any kind of help


Question: Culinary uses for juniper extract?
Answer: I agree with nixy. Make sure it's food grade. If it's not the extract may have other stabilizers that you don't want to consume. Glycerin is an example where glycerin that you use in soap is different from the food grade glycerin one would use to make non-alcoholic vanilla extract.
