Problem Description

We have a custom URL protocol (hxcrypt://) which launches an application on our side. First it works, but on a subsequent edit of this page, the <a ... /> tag is still there, but the href attribute is missing.

Do we need to register the URL somewhere in the system?

Failed Workarounds

Not setting a link name
Link inside or outside of a table
Escaping the hash in the url

Steps to Reproduce

Create a Web Link on a page with the following parameters:

URL: hxcrypt://eyJTYWx0IjoiM0V5dC9hc2IyWENVVzFIOEFSRTVueDdiTjdDeEEwT254YUE5ZFhjWFlMa1FPTkVLVlVwYWdscXFDcDBEWHV2dE41dERNM01OU1NLRkhkYUFMbjVicFE9PSIsIkNyeXB0b0hhc2giOiJxTUk2Z1g3NnAvZ1NUUjdqUUlZam13PT0ifQ==

Name: Test

Save the page. Then edit the page, change something in the document, then save again. The web link is now broken.

Are your users using plain text or the link option? How have you customised the link option to understand the new non-standard protocol?

Hexabit GmbH

We use the 'Link' button in the toolbar. I did not have to customize anything on the JIRA/Confluence side. The protocol is registered in the Windows Registry and works with a custom application we developed.

Nic Brough -Adaptavist-

Ok. Confluence does not recognise that as a valid link, so it does not save it as a link. That's why I asked what you had customised, because you need to hack the code in confluence to tell it that this should be treated as a link.

Hexabit GmbH

That's not entirely true. The first time around, it works and it recognizes the link as valid. When I save, everything works, the click launchers our software, everthing perfect. But, when I go on to edit the page again at some later time, the link will be gone.

Is it possible to tell confluence, that the hxcrypt:// protocol is valid?

Nic Brough -Adaptavist-

You would have to hack the code.

The reason that it seems valid at first until edited is probably that the "create link" code has been written to accept anything without validation because users may post invalid stuff. Editing is expected to put valid things in.
