When using Patterns in the 1.5 update, boolean values are not staying their set value when using Patterns after content is edited. To reproduce: Add a component that uses a boolean value, set with a default 'true', and a basic text field. In my example this boolean was used to show/hide a section of markup. Create a page with this component added, but set the boolean to 'false', then create a pattern with this layout. Add a new page, and drag the pattern over, which should have this boolean set to 'false' hiding the markup. Edit the text field. When the preview reloads, the formerly hidden section will now display, but the boolean will still show in the off position.
