Re: [FreeMarker-user] Display String array in FTL

[strutstwouser <str...@gm...>]

I looked at the PostalAddress object closer and find that in addition to the
usual get/sets : 

    public java.lang.String[] getAddressLine() {
        return addressLine;
    }

and 

    public void setAddressLine(java.lang.String[] addressLine) {
        this.addressLine = addressLine;
    }

there are also methods like : 

    public java.lang.String getAddressLine(int i) {
        return addressLine[i];
    }

and 

    public void setAddressLine(int i, java.lang.String value) {
        addressLine[i] = value;
    }

When i removed these additional get/sets, it worked fine.

I've attached the stacktrace ; 
http://www.nabble.com/file/p23703551/stacktrace.txt stacktrace.txt  the NPE
is at the bottom. Sorry i initially thought that was the primary exception.

Thanks,
Joseph
