When I use the search option from the toolbar, the search dial is appears.
If the first field is a dropdownlist and if the defaut selected item is the one I want, there is an issue.

In this case, the data send in filter is '' instead of the value set in searchoptions/value.
If I change the item in the dropdownlist and I come back to the default, there is no problem.

So, the issue is only at init.

Thanks
