PresetOptions for a RelativeDateItem

Hello,

the documentation for the presetOptions of a RelativeDateItem decribe the following default:
{
"$today" : "Today",
"$yesterday" : "Yesterday",
"$tomorrow" : "Tomorrow",
"-1w" : "Current day of last week",
"+1w" : "Current day of next week",
"-1m" : "Current day of last month",
"+1m" : "Current day of next month"
}

But the "Current day of last month" is missing in the implementation. See I18nUtil.Java line 737.

We are using SmartGWT 4.1

Regards

Peter
