[Users] GeocoderComboBox and minChars option

[Thomas Becker]

Hi,

I try to control the minimum number of characters entered in a GeocoderComboBox befor the combobox gets filled with suggestions. The combobox is within an item in a bbar and I set the option right after setting the xtype. As far as I can see from the documentation the default value is set the 3, but even if I do not set the minChar option at all the combobox will be filled with suggestions right after I punched in the first character.

Is there anything specific that I am missing?

Thanks in advance for your replies,
Tom
