Subject Re: Correct Task Behaviour
Date Tue, 16 Oct 2007 10:14:59 GMT
Thanks for the responses.

I think my problem came from accepting the file attribute as a String and
then converting it to a file in my code. I guess if I do something like the
below I shall get the correct behaviour.

public void setSrcFile(File srcFile) {

......

}

Cheers,

Matt
