Taking another look at the comment in the Form Builder class I noticed a mention about putting these hook methods in to my auto generated DataObjects before passing them in to the FormBuilder method. Seems fair enough. Would be good to see even a rough skeleton of a manual on the PEAR website for this package. I noticed in another email dated back on 14/04/2004 you mention examples for FormBuilder. I never found these as the PEAR command line installer doesn't put Examples anywhere - oops! Will go examine the examples in CVS now. Regards, Mike C. ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
