- Create a structure with a Text-Field with the name e.g. 'Artikel-Text'.
- Create a new webcontent for this structure
- Save -> it won't be saved (only in FF and Chrome, IE should work) without any error or success message.
The cause is that Liferay creates a JS function with the field name in the JS function name and when this contains a '.' or a '-' the JS syntax is broken.
