Error in using StringArrayConverter

[Marco Mistroni <mm...@gmail.com>]

Hello all,
 i am writing a JSF app using mYFaces..
In one of my pages, i have a h:selectManyCheckbox input field, which is
mapped to
a String[] property on my backed bean.
 after stumbling against the 'Invalid value' entered, i found out that there
is a converter
for a String[] array in myfaces, the StringArrayConverter.
 so i defined the converter in my faces-config.xml and declared it in the
h:selectManyCheckbox
input field.
At bean creation, i am even initializing the String array with values
{"foo", "bar"}
 However, when the page gets loaded , i am receiving the following exception
:
 2005-10-15 15:56:21,937 ERROR [
