Bug: Support Example Demo - cannot read property "length" of undefined about vue-flow-form HOT 5 CLOSED

I am unable to reproduce your issue, can you explain how exactly are you using the example and where exactly is the issue happening? If you have any source code samples, this might be helpful as well. Also, make sure you're using the latest version of the example since we made a few changes to all examples recently.

I can't see what the problem is. Did yarn add, made changes in file for imports. I am using it in a Nuxt SPA, created a page with the example code. I get this in the console:

TypeError: Cannot read property 'length' of undefined at VueComponent.setQuestionListActivePath (webpack-internal:///./node_modules/@ditdot-dev/vue-flow-form/dist/vue-flow-form.common.js:2878) at VueComponent.setQuestions (webpack-internal:///./node_modules/@ditdot-dev/vue-flow-form/dist/vue-flow-form.common.js:2867) at VueComponent.mounted (webpack-internal:///./node_modules/@ditdot-dev/vue-flow-form/dist/vue-flow-form.common.js:2770) at invokeWithErrorHandling (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:1853) at callHook (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:4213) at Object.insert (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:3136) at invokeInsertHook (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:6336) at Vue.patch [as __patch__] (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:6555) at Vue._update (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:3939) at Vue.updateComponent (webpack-internal:///./node_modules/vue/dist/vue.runtime.esm.js:4054) _callee$ @ webpack-internal:///./.nuxt/client.js:233

Are you using the latest version (1.1.6)? Can you please post a code example that results in this error? From what I'm seeing in the errors, you're not correctly passing the questions array to Vue Flow Form. In any case, this behavior was slightly changed in the latest version, so even if you don't pass a questions array, or if you pass an empty one, there'll be no errors, but will result in an empty screen (since we don't have anything to display).

Hi, I solved the issue, I needed to add LinkOption to the necessary components. It's missing in your example for those using npm (but included in your default import).

import FlowForm, { QuestionModel, QuestionType, ChoiceOption, LinkOption, LanguageModel } from '@ditdot-dev/vue-flow-form'

Thanks so much for your help, and thanks for this great component.

No problem at all and thanks for the heads-up, we'll be sure to include this in the next update.
