Check line enable/disable state when a new page is selected:
Some lines may change the enable/disable state based on events which are triggered from outside the page scope (for example sensor setup). Updating the line states while another page is active caused problems in the framebuffer handling. To solve this usecase the conditions for the line dis/enabling is checked when a "nextPage" is selected. If condition changed then the page will be refreshed.
