ui problem : Our one of application use spring mvc+jqery .
we also use huge jquery and json for ui scripting (send/retrieve/validation).
this application 300 page /form.
we almost finish our development , we are doing testing and facing one problem :
lots of silly bugs(ui) from different silly point .
From my understanding reason of this kind bug is :
use different ui in different style like : validation pattern, grid , form , masking, different type js plugin.

         1. plain form(grid)/Tabbed form
         2. inline edit grid
         4. add to grid
         5. cyle based grid
         6. Search result grid / partial grid editing


          But our maximum page has same category functionality.
          How to organize our page /form minimum set of pattern 
          that perform easy maintenance in ui layer .

I have confusion about large scale financial application ui layout .
i have some idea but i am not clear here .
From my experience ,

this one of critical issue in enterprise application development .

how to use a common ui pattern for whole application ui ??
pls give me some suggestion how to minimize this problem
* this ui pattern provide UI designers and developers with a common way to think about the problem at hand and provide a baseline design that can be customized to your specific application needs*
