service for this?
Okay, here is my solution for now:
I created a class SimpleField which implements the Field interface and
has a public method for setting the control name.
The onValidateFrom-method for each field remembers the controlName for
the checkbox in each row of the grid. Then I injected the SimpleField
into the page. In onValidateForm I am iterating over all selected rows,
setting the control name of the SimpleField to the remembered one and
recording an error with it if needed.
Tapestry Developers, please:
- enable validation for checkBoxes. The simplest case I can imagine is a
"required" validator when accepting licenses on web pages.
- Provide a way to retrieve single field instances from a loop or grid
so that my above hack is not needed.
Regards
Stephan
