If you encounter this problem, you are probably just took a hand to the project, then your project is a low-hungry version of what version or covering some of the functions of the components of the source code
or write in the manner of the original developers, either have the ability to modify the source code covered under the source code or
you can, laozi is cattle X, rewritten or another ui framework
If you find you can upgrade ui framework but does not affect the original version of the old development mode, please let us know (I've been tired of the old version)
