On a clean installation of 7.11.3 I am unable to add new Case Updates via the Edit View window - this is the window that offers the TinyMCE editor. Attachments are however added. Adding updates via the Detail View works fine
On an upgraded 7.11.3 DEV copy of my live system (itself upgraded system from 7.0 up through the ages to 7.9.4) it does however partially work, though in this case it only stores the first paragraph
@pgr - Thanks for this information - it is exactly the problem
I found the thread you mentioned after posting, and I have also contributed to that. It seems there is a bug in that blank information is being passed as the Case Update_text. The workaround suggests that the problem may be because the page is trying to use two instances of the TinyMCE HTML editor, and causing confusion.
So my workaround, as detailed in the thread is to simply stop that page from using the HTML editor for the description - in my case I did this by adding a line to my customisatons file for Cases (custom/Extension/modules/Cases/Ext/Vardef/customisations.php)
…
$dictionary[‘Case’][‘fields’][‘description’][‘editor’]=‘text’;
…
Appreciate your help, and if other people see this suggest they also see the thread kindly linked by @pgr above.
