Date format issue with Live Data when not using default format

Reproduction steps:

• Create an xclass containing a Date property aiming to contain dates without hours (format dd/MM/YYYY)
• Create some entries
• Create a livedata for those xobjects and specify that the property is of type Date in the LiveData, to get both the filters and the displayers

Expected result:

• the date are properly output and we can use the filters

Obtained result:

• the LD displays "Bad date format", even using some meta property in the LD to specify the format doesn't work to make it work. The filter doesn't have any effect.
