Oxygen XML Editor keeps crashing

[antonyterrence]

Hi Team,
Suddenly, Oxygen XML Editor on my system stopped working. When I try to start it, I keep getting this error:

Code: Select all

Cannot start <oXygen/> XML Editor.
Due to:java.lang.NullPointerException
Cannot invoke "java.net.URL.toExternalForm()" because the return value of "ro.sync.ecss.component.editor.heavy.f.tiv(ro.sync.ecss.extensions.api.editor.AuthorInplaceContext)" is null.

Hi Antony,

I assume you are using Oxygen 25, I added an internal issue to look into this on our side:

EXM-52160 NullPointerException in browser form control

Did you customize the DITA framework configuration with your own CSS styles?
Have you started using the "oxy_browser(...)" form control for anything in your CSS? If so, what does the CSS selector look like?
Are you using DITA <object> elements in your topics?
For example:

Code: Select all

<object
                data="https://www.youtube.com/embed/Yfr6WDFN7d0" outputclass="iframe"/>

Regards,
Radu

Hi,
As an update, we released Oxygen 25.1 which should have a fix for this problem.
