### Version 2.5.5 ### Reproduction link [https://github.com/VdustR/vue-issue-7084](https://github.com/VdustR/vue-issue-7084) ### Steps to reproduce ```text # install dependencies npm install # serve with hot reload at localhost:8080 npm run dev ``` ### What is expected? Compiled successfully. ### What is actually happening? Got error: ```text - :value conflicts with v-model on the same element because the latter already expands to a value binding internally ``` --- The new improvements from v2.5.5 > warn if both v-model and v-bind:value are used on same element conflicts with [Customizing Component `v-model`](https://vuejs.org/v2/guide/components.html#Customizing-Component-v-model). Downgrade the vue(vue-template-compiler exactly) in the reproduction to 2.5.4 and it will be compiled successfully. BTW, Production vue.js works fine -> [CodePen](https://codepen.io/VdustR/pen/vWpOvv) <!-- generated by vue-issues. DO NOT REMOVE -->
