Hi I've modified http://localhost:8080/xwiki/bin/view/XWiki/XWikiSkins with the class editor. I've used the Add Property Panel to add a property "toucan.css" of type TextArea In the editor i set the size of the property to 100000 (toucan.css is a very large file) I've tried to set the type to PureText and FullyRendered... THen I modify the default skin on http://localhost:8080/xwiki/bin/edit/XWiki/DefaultSkin?editor=object&classna... I copy and paste the content of the original toucan.css in the toucan field Try to save but: problem occurred while trying to process your request. Please contact the webmaster if this happens again. Detailed information: Error number 3201 in 3: Exception while saving document XWiki.DefaultSkin Wrapped Exception: Row was updated or deleted by another transaction (or unsaved-value mapping was
