• Type: Bug
• Status: Closed
• Resolution: Won't Fix
• Affects Version/s: 7.0.0 DXP FP32, 7.0.X, Master
• Fix Version/s: None
• Component/s: Portal Services > Localization, Tags
• Labels:

• Fix Priority: 4

Reproduction Steps:

1.In your portal-ext.properties file, set up these properties:

locales=fi_FI,en_US
locales.enabled=fi_FI,en_US
company.default.locale=fi_FI
locale.prepend.friendly.url.style=0

2. Start the portal and create a new page:
Page name can be: test1
Click "Add Page"

3. Configure the page to have an English and a Finnish friendly url by clicking on the 3 dots next to the page name (test1), and then select: "Configure Page"
In the "Friendly URL" section, you can define the language specific page names by entering this for example:

• click on the Finnish icon:
  the "http://localhost:8080/web/guest" part is pre-filled, you just have to type: "/fitest"
• click on the English icon:
  the "http://localhost:8080/web/guest" part is pre-filled, you just have to type: "/entest"

4. Visit the fitest page and:
4.1 Type "en" in front of the "/web/guest/fitest" in the url, so it will become:
http://localhost:8080/en/web/guest/fitest
The portal will redirect to:
http://localhost:8080/web/guest/entest
4.2 Type "fi" in front of the "/web/guest/entest" in the url, so it will become:
http://localhost:8080/fi/web/guest/entest
The portal will redirect to:
http://localhost:8080/web/guest/fitest
4.3 Again, type "en" in front of the "/web/guest/fitest" in the url, so it will become:
http://localhost:8080/en/web/guest/fitest
This time, the portal will not redirect, it will stay on the English page, unless you clear out your browser's cache.

Expected Behavior:
the portal should redirect to the English version of the page.

Note:
redirection works when setting:
locale.prepend.friendly.url.style=2
