Hi, I have a class named MyClass with "content" property with type TextArea. I write some Groovy code to read a text file (*.txt) with encoding UTF-8, and print each line in the screen (code snippet 1) , no errors. but when I replace code snippet (1) with (2), the following error occurs: com.xpn.xwiki.XWikiException: Error number 3201 in 3: Exception while saving document ..Wrapped Exception: could not insert: xpn.xwiki.objects.Large String Property?<http://localhost:8080/xwiki/bin/edit/com.xpn.xwiki.objects/LargeStringProperty?parent=Nga.ImportCorpus&editor=wysiwyg> I try text files with encoding Unicode, replace UTF-8 with UNICODE, execute code snippet (1) and (2), both are ok. Anyone can explain me why I'm getting error with UTF-8 and how to solve this problem ? My code here: *byte[] bytes=... String[] lines=new String(bytes,"UTF-8").split("\n"); list=mydoc.getObjects("XWiki.MyClass"); for (i in 0..<lines.length) { (1) println lines[i]; (2) newobj=mydoc.newObject("XWiki.MyClass"); newobj.set("content", lines[i]); list.add(newobj); } mydoc.save();* -- Ngô Thị Hồng Nga
