TextArea with list of strings.
I am trying to make a TextArea that allows you to input a list of
strings (separated by a newline) and turns that list into a Collection.
I had it working but it was kind of hacked together, I'm trying to do it
the clean way now.
I have it working except for two things:
If I give it an empty collection for the model object then it display
square brackets [] inside the text area.
I don't have the conversion 100% working. Like when you have a
TextFieldDate, I'm trying to make it do the same thing to each line.
It works, but when it is an invalid value, instead of a nice error
message X is not a valid Y I get a runtime exception from whatever
IConverter I am using.

Re: TextArea with list of strings.
you should do convertToObject() call in a try block, catch any
exception and throw a conversionexception

No I'm getting a ConversionException, I must have made a typo. But for
the single text field I get a message in the feedback panel.

ok, override convertValue() instead of convertInput() and then the
