I have created a set of forms based on the HowTo document and when I click on an item in the ListShow form displayed in the iView I get the raw XML displayed instead of a rendered Show form. A collegue has also tried with a new form and got exactly the same result.
Also, when we change a form, labels update almost immediately but any changes to fields don't show up untill the following day. Not sure if this is related or a separate issue but I guess the server has a few problems. We're using EP5 SP5.
