Dynamic properties are still using the EPiServer 5-6 property system so you have to develop these the old fashion way until we make them use the EPiServer 7 model.
That worked out! Thanks.
Is the answer you gave here connected to my problem described at: http://world.episerver.com/Forum/Developer-forum/EPiServer-7-CMS/Thread-Container/2013/5/Dynamic-property-drop-down-list-populated-from-code/ ?
I have a custom property that works fine on pages, but when I add it as Dynamic Property it won't show up on 'Edit dynamic properties'-view as it should. Are there limitations or known bugs conserning custom properties as dynamic properties?
My custom property uses custom data model too. Might it cause the problem with dynamic properties?
