PREREQUISITE: set the system property -Dhttp.nonProxyHosts=*.local,169.254/16 before running the app server. For Mac OS computers, this is defaulted in the Operating System's System Preferences.

Steps to reproduce:

1. Navigate to Content > Forms;
2. Add a form named "Address";
3. Add two text field named "Postal code" and "Prefectures" as required fields;
4. Navigate back to Forms home and add a data provider as the following settings:
   • Name: zipcloud
   • URL: "http://zipcloud.ibsnet.co.jp/api/search?zipcode={zipcode}"
   • Inputs:
     • Label: zipcode
     • Parameter: zipcode
     • Type: Text
     • Required: true
   • Outputs:
     • Label: prefecture
     • Path: $.results[0].address1
     • Type: Text
5. Navigate back to Forms home and select "Address";
6. Add a rule as the following settings:
   • If Field [Postal Code] is not empty Autofill [Prefectures] from Data Provider zipcloud
7. Add a form portlet to any page and set "Address" form;
8. Input "1500000" to "Postal code" field.

Actual result:
Prefectures field is not filled with provided value.

Expected result:
Prefectures field should be filled with "東京都".
