If you configure a component o have a link field containing the property : “targetTreeRootPath” and setting it to any parent node in the pages app hierarchy, then the pages that get displayed on the pages app become the child nodes of this root path.

I have attached the files I was working with. You can use them to test as well.

Steps:

• Create a component with a link field that contains the property “targetTreeRootPath” (Or use the component "treeRootPathTest_component")
• Create a page and add this component to the page.
• Open the page and open the dialog for the component
• At this point, no edits have to be made on the dialog, simply opening the dialog is enough
• Close the dialog.
• Close the page.
• Access the pages app again

Actual Result
You will see that the pages displayed are now those under the dialog's configured “targetTreeRootPath”

Expected:
TargetTreeRootPath should only affect dialog link field choosing windows. It should not affect anything else.

 This is happening with the Magnolia 5 UI Framework within Magnolia 6.2.2

Also check 6.2.3 to make sure. It's likely the old configuration converted into new framework?
