I'm seeing the same issue

Forms 4.1.5 + Umbraco 7.3.4

I also had the issue with Umbraco 7.3.1 + Forms 4.1.5, and Forms 4.1.4.

No one else has this issue?

Ben and I are the only ones to see anything like this?

I know that Stijn (https://our.umbraco.org/member/151879) is not having the problem... what is unique about my and Ben's server /configuration /circumstance? Anything else that anyone can think to try?

ljcooper, are you using MVC or Web Forms? In my setup I am using Web Forms. If I get time I will setup a separate Umbraco Instance with MVC instead and see if that makes a difference.

Before I go further, I tested this in the following browsers and found that it was doing the same thing across the board:

• Chrome (48.0.2564.109 m)
• FireFox (44.0.2)
• IE 11
• IE 10

When I was testing IE 10 I noticed that there was a Javascript Error:

Chrome is throwing "Uncaught SyntaxError: Unexpected end of input".

FireFox is throwing this:

Debugging the Javascript I found that formId contains a guid. However, $("#values_" + formId).val() only contains "{" which is breaking the JSON.parse function.

Ben,

I am seeing this issue too.

The javascript is due to encoding of json in the hidden fields. The easiest solution is to change the quotes of the value in the partial to single quotes:

<input type="hidden" name="values_xxx" value='BLA' />

Kind regards
Damiaan

Thanks Damiaan. I tried that and it did remove the javascript error that I had found. However, it looks like my guess for why the validation is removing the user input was incorrect.

On forms where I have any validation all of the user's input is still disappearing if something is invalid.

Is anyone able to use Validation with Umbraco Forms?

We haven't been able to on more than 4 implementations (webforms and mvc). Either we're doing something unbelievably wrong every time, or something is broken somewhere, I haven't had the time to invest to try to figure out the bug.

If you can reproduce the problem on a clean umbraco installation, create an issue on http://issues.umbraco.org. I don't have spare time to do so. Don't forget to mention this thread in the issue (and the other way around).

I tried to log the issue on the http://issues.umbraco.org site but I can't login. I click on guest in the upper right corner and then Log in. This seems to be giving me a Javascript error "Uncaught TypeError: Cannot read property 'logout' of null"

I have tried to login with both Chrome and FireFox with the same results.

Here are the steps that I went through to reproduce the problem with Umbraco Forms:

1. Manually Installed Umbraco v7.4.1 without anything extra
2. In config/umbracoSettings.config set defaultRenderingEngine to WebForms
3. Installed Umbraco Forms by going to Forms on the left nav and clicking on the blue "Install" button
4. Created a document that only has one field, a Macro that only allows "Insert Form"
5. Have the template output the form that was selected and insert a script reference to jQuery in the head tag
6. Created a simple form with 3 text fields, the first two being mandatory and the last one being optional
7. Created a new page, select the form that was just created, and Save and Publish it
8. Visit the new page
9. Fill in only the first mandatory field and submit
10. The page refreshes and the user input is gone, leaving only and indication of which fields were missed.

If I can login to http://issues.umbraco.org I will post the problem there.

You need to create a new account on issues.umbraco.org. It's not single sign on.

This is the url to create an account: http://issues.umbraco.org/registerUserForm

Thanks Damiaan. I already have an account, I just can't login to the site. It seems that I am not the only one not able to login:

https://our.umbraco.org/forum/umbraco-7/using-umbraco-7/75556-cant-login-to-umbraco-issues#comment-241687

I will keep trying the Issues site throughout the day and will post the bug there once I am able to login.

Hi Damiaan. I found I was able to use the login link from the Register User Form link you provided. Thanks!

I have posted the issue here:
