Updated from 1.0.9 to 1.0.10 and date template variables (datepicker) behaved strange.
When two date template variables were near each other in the template variables list the top one displayed under the bottom one.
Some sort of z-index problem.
I solved it by changing line 805 in manager/actions/mutate_content.dynamic.php from:
'z-index:'. $zindex : ''),'">'
to:
'z-index:{$zindex};'
Is this a bug or a new behaviour in 1.0.10?
