"Error when evaluating expression validation.name.invalid"

[dwightjack]

Hi,

great work on this plugin!

When I access to the validation object, i got in the console the following message:

[Vue warn]: Error when evaluating expression "validation.name.invalid"

While this doesn't break the application I wonder if I'm missing something in the setup.

Thanks in advance!

I think that there are not problem in your setup code.
This is small problem of vue-validator.

See http://vuejs.org/guide/best-practices.html#Data_Initialization

But it does not effect in application behavior.
That's OK. 😄

In the v2.0, I'm going to resolve it !

Ok thanks for the explanation!

I met the same problem.If the level is too much,it's not convenient to initialize data like this instead of an empty object.I do this now:

validation&&validation.form.name.invalid

I found if I turned on Vue.config.debug, Vue will throw exception, the app will stop working.

I can also verify this. My application was breaking until I set Vue.config.debug to false. I get the same warning, although that app now behaves as expected.

Sorry, I cannot find a solution to this issue yet.
This issue is difficult.

I'm asking the advise about related issue at below forum.

http://forum.vuejs.org/topic/957/how-to-avoid-evaluating-expression-warning-for-plugin-author

This issue is occuring when we using development version of vue.js

In development of app, we can avoid this issue by setting the Vue.config.warnExpressionErrors = false.

I'll try to write the README.md later. 😸
