Conditional Logic no longer working after upgrade to forms 8.3.0

[yorky002]

We just upgraded our version of forms from 8.2.0 to 8.3.0 and conditional logic has stopped working.

Have tried saving a change to an existing form.

No js errors are thrown.

An update on this:
When conditional logic is applied to a value with spaces the logic does not fire. When a single word value is used in the condition it works fine.

Issue:
Expected value has spaces replaced by +.
Value is as per form (still containing spaces)

Fix applied as follows:
File: App_Plugins/UmbracoForms/Assets/themes/default/umbracoforms.js

Added the following to the self.operators (line 214) for each check:

if (typeof(value) !== 'undefined') { value = value.replace(/ /g, '+'); }

Thanks for reporting @yorky002, we'll have to investigate. Are you sure this used to work in 8.2.0 with spaces?

@yorky002 @nul800sebastiaan I'm also seeing this and it was working in 8.2.0 for me also (I'm 99% sure). In my instance I've noticed the following in the console. I don't know if this is related or not

Hi @nul800sebastiaan ,

Yes 100% it used to work prior to the upgrade from 8.2.0 to 8.3.0. Working just before upgrade, not working afterwards.

Cheers,
Kate

Workaround:

In /Views/Partials/Forms/Themes/default/Script.cshtml use Uri.EscapeUriString instead of HttpUtility.UrlEncode.

The difference is that space is encoded as %20 instead of +. And the javascript in the condition logic decodes %20 back into space.

Just experienced the unexpected JSON token issue after upgrade to 8.3.0, worked fine on earlier version. Found that line 25 in App_Plugins\UmbracoForms\Assets\themes\default\umbracoforms.js has been updated to:
init({ form: JSON.parse(unescape(formsCollection[i]))});

changed back to
init({ form: formsCollection[i]});

and now the conditional logic works with no js errors

Spent hours trying to the conditions to work trying work-arounds and this finally worked for me! thank you
