WebOffice WebOffice core client messages
When having left the page in the browser the WebOffice core client has showed a message by default. The same behaviour occurred when having changed the language in the WebOffice 10.9 project.
You can suppress those messages in the WebOffice core client by adjusting the file language_weboffice_user.xml in C:\Tomcat\webapps\<WebOffice Applikation>\client_core\jss\language_weboffice_user.xml.
Note: With the patch of 13.12.2016 this message has been deactivated by default.
Browser message when leaving the website
In the file language_weboffice_user.xml there is the key (e.g. <locale key="en"> for english) for all languages. To suppress the message in the client please replace the entry in WebOffice message (Key WEBOFFICE.MESSAGE.EXIT) with a blank.
Please consider, that the entry <record jsxid="WEBOFFICE.MESSAGE.EXIT" jstext=""/> has to be done in every single language.
