Hi Rui, i was looking in the actual webpart's section. I've now finally figured out that the 'examples' is a separate page in the Pages application haha (may be useful to mention this in the documentation).
When i try to implement the Page type and widget solution you show in your video, i run into the following error when trying to place the widget (i double checked that everything is the same as mention in your video):
SELECT TOP 1 [Content], [DocumentCulture], [NodeID], [NodeLinkedNodeID], [NodeSiteID], [ClassName], [NodeLevel], [NodeOrder], [NodeParentID], [DocumentCheckedOutVersionHistoryID]
FROM View_CMS_Tree_Joined AS V WITH (NOLOCK, NOEXPAND) LEFT OUTER JOIN COM_SKU AS S WITH (NOLOCK) ON [V].[NodeSKUID] = [S].[SKUID]
WHERE [NodeSiteID] = @NodeSiteID AND ([NodeAliasPath] = @NodeAliasPath AND [DocumentCulture] = @DocumentCulture)
Invalid column name 'Content'.
I've figured out it has something to do with the Columns property on the widget which you set on 4m04s in your youtube video. Because when i change this value, the value in the error message also changes. I've checked to make sure that the 'page type'-field is also correctly set to 'Content'. What could be causing this error?
