Version 10 ignores component rendering conditions based on field value

I upgraded to version ten to fix a problem with picklist fields and Salesforce Summer. I forgot to check one of my pages before I upgraded production and, of course, that is the page with issues. I have a complex page with a lot of conditionally rendered components based on the value of a UI only field in a salesforce model. I have buttons/nav components that update the value of the UI only field which triggers the show or hide of the component. 
Unfortunately now, all components are rendering upon page load and they don't respond to changes in the UI only field.  As there are so many components and as some components are complex page includes, the page load takes forever and is just a jumbled mess of components stretching down the page. 
I tried the new component rendering feature in version 10. It doesn't work. I love the idea and it is easy to implement, but there is no response to the show, hide, or toggle action being triggered by a button press. Also with this new functionality, I don't see an option to have the component in hidden status upon page load. I need these components to be hidden until triggered by  button push. 
Any help would be greatly appreciated.
