Wrong values shown in detail view using IE9

[GunnarK]

In IE9 the detail view of an entity can show wrong values.
This can be reproduced in the demo application by the following steps:

1. Click on an info button of an entity
2. In the detail view click the edit button
3. Edit the entity and save
4. In the detail view now shown the edited values are not shown, instead the old values are still displayed.
   Other pages, like the list view and quick view show the values correctly.

I was able to reproduce this behaviour with 1.2.0.RC1 in a local installation. This cannot be reproduced when using Firefox (v38).
Debugging locally I saw that the getter of the Hibernate entity is not called when the detail view is shown. It is called for all other pages.
