Hi list !
A recent discussion on the users list [1] showed that there is interest
in implementing a minimum/maximum number of rows check in CForm's repeaters.
Jorg Heymans submitted a patch to bugzilla [2], that adds the
minimum-size and maximum-size attributes to the repeaters definition,
and contains a sample on disabling the controls with jx macros...
To complete this feature validation should be added. So, if the current
size is lower or greater than the specified values, a validation message
should be displayed, and the add-row or remove-row buttons should be
disabled.
Now the question for the CForm gurus :-):
What's the best way to do it ?
We've found two scenarios so far:
-try to add the validation in the validate function of Repeater.java and
disable the controls in Repeater.java
-write a validator class (like the ones described in [3]), set a flag,
and leave enabling/disabling of the controls to the presentation layer
(the forms-field-styling.xsl, or jx macros..?)
I'll try to implement it, but some advice where to start, and what to
touch would really be great, as am I still a CForms greenhorn :-).
Regards,
Tom
