redo:
1. create a form add a textbox
2. set readonly = true, disable = true for textbox
3. when page is show on browse. use chrome development tool to delete attribute readonly="readonly" and disable
4. now user can edit value of text field
5. it's ok but when use move out of text field, this value is sync to server
==========
do you think we should add a new attribute like disableClientEdit so we can avoid this kind of hack?
or maybe already have solution for this issue?
