APEX Validation: Check overlapping time periods

There is a easy way to check if a row with overlapping time periods exists inside you table.

All you need to do is to create the following APEX validation:
We assume that our table is called T_MACHINE with the columns m_id (PK), valid_from and valid_until Validation type: NOT Exist

select 1 from T_MACHINE

Scroll to the top of your page/report

In case you use partial page refresh inside your reports you may have encountered an issue that you always stay on the bottom of the page even after the refresh of the report.  One of my customer marked this as a bug and meant that after the refresh the display position should be at the beginning of the report.

Seems complicated but worked out to be really easy:
Add a dynamic action: After refresh of your report execute this javascript statement

/* Scroll to Top */
$("html, body").animate({ scrollTop: 0 }, 0);

Barcode Report

This example seems still to be interesting to some people in the community. The number of requests and questions I am getting regarding it forced me to update it. Now the rendering is using an application process instead of a public procedure - using public procedures in XE is somewhat tricky.
