I need to present a form where a text box displays something rather than nothing when the associated value is empty, for example see the behaviour of the search input at http://java.sun.com/. This seems to be much like the selection-list's null-text facility which obviously isn't available on normal text fields. I was wondering whether anyone could point me to any existing examples and/or advice on how to achieve this affect within the cforms framework?
What about doing this only as presentation concern, i.e. handling this for example in the stylesheet?
An avenue I was looking into was to implement a converter to special case the empty value but since I'm dealing with strings I'm put off by the converter documentation saying "Strings obviously don't support any convertors, since there's no purpose in converting a string to a string".
So you see the comment is not quite true :)
I've also tried building javascript event handlers and validators but managed to get myself in an infinite loop using the following:
That's obvious. You change the value and this leads again to on-value-changed.
