I have a layout with two place holders leftColumn and rightColumn. For an item i am adding multiple sublayouts for leftcolumn and multiple sublayouts for rightcolumn. Now in page editor when i am trying to change position using "Change Position" button in toolbar and move content to another location, content is getting moved to my new location as desired. But when i click Save button on Ribbon, it is actually deleting moved content from presentation itself.
I am not sure why it is behaving like this. we are using Sitecore 6.4
We opened a ticket with Sitecore and found out that this is an existing bug. They do not support movement of multiple controls/sublayouts within same placeholder on layout using PageEditor. We need to use multiple placeholder on layout and then we can change position of controls from one placeholder to another one.
