TYPO3 Core

There are several issue with single tasks

• If an enddate is set, saving the task without the disabled checkbox will result in an exception http://wiki.typo3.org/Exception/v4/1250715544
• If a next execution is set, but it is after enddate, then the task will always be shown as late
• switching from a recurring task to a single task will likely result in strange situations

The save action must make sure to clear related fields before saving the task.

The next execution time function must also handle the endtime error more gracefully --> another issue.
