Hi Don,
In the demo app using the Horizontal Week Planner menu option, click on a blank spot to add a new appointment. After you complete the entry nothing shows in the planner until you refresh the form by clicking on another appointment or change the date selector, then the new appointment "bars" show up.
Second issue seems to be when using IE, specifically IE 10 in my case. Open one of those new appointments created in the previous step and click the delete button. The record is deleted but the graphic in the planner does not disappear. Now click on another appointment block in the planner, poof, record not found error alert. Cancel out of that and the deleted record graphic now disappears and you can now edit an existing entry.
Please let me know if you are able to duplicate that in the demo app.
Regards
Parker
