Describe the bug

myFiles object doesn't get binded after any change. I'm using V6 with Nuxt.js V2.

             <div>
                  <client-only>

Reproduction

Created a component including user profile form, and added this component to it in the right fields.

Environment

- Device: Macbook Pro 2015
- OS: macOS 11.6
- Browser: Brave/Firefox.
- Vue version: Nuxt.js 2.15.8

Please provide a test case. It looks like you're not overwriting the myFiles object just pushing and splicing so vue might not catch the update? I advice to test without using plugins first.

I had the same issue binding to files did nothing. I ended up just using the updateFiles event and setting the parameter to a component variable. This should work for you 😀

<template>
<div>
    <file-pond name="test" ref="pond" label-idle="Drop files here..." v-bind:allow-multiple="true" accepted-file-types="image/jpeg, image/png" v-on:updatefiles="updateFiles" />
</div>
</template>

<script>
// Import Vue FilePond
import vueFilePond from "vue-filepond";

// Import FilePond styles
import "filepond/dist/filepond.min.css";

// Import image preview plugin styles
import "filepond-plugin-image-preview/dist/filepond-plugin-image-preview.min.css";

// Import image preview and file type validation plugins
import FilePondPluginFileValidateType from "filepond-plugin-file-validate-type";
import FilePondPluginImagePreview from "filepond-plugin-image-preview";

// Create component
const FilePond = vueFilePond(
    FilePondPluginFileValidateType,
    FilePondPluginImagePreview
);

export default {
    name: "app",
    data: function () {
        return {
            myFiles: []
        };
    },
    methods: {
        updateFiles(files) {
            this.myFiles = files;
            this.$root.$emit('updatePendingFiles', this.myFiles);
        },
    },

    components: {
        FilePond,
    },
};
</script>

Your issue is very simple, you're not using events but props, so your methods will never be called (the casing is also wrong)

Instead of

                      :init="handleFilePondInit"
                      :processFile="handleFilePondProcessfile"
                      :removeFile="handleFilePondRemovefile"
                      :addfile="handleOnaddfile"

Use

                      @init="handleFilePondInit"
                      @processfile="handleFilePondProcessfile"
                      @removefile="handleFilePondRemovefile"
                      @addfile="handleOnaddfile"
