Error reporting on UPD3 screen [message #3053]

I use an UPD3 pattern modeled exactly as you decsribe in in the documentation using fieldname and fieldvalue to maintain separate rows of data for fields in a single screen. This works great.

However, I now want to add some validation code to ensure that two separate fieldvalues do not conflict logically - and instruct the user that the particular combination cannot be used.

I have added some validation in _cm_updateSelection() which correctly displays my error message if the validation fails. However, the upd3 screen then fails to display all the field values correctly as in the fieldspec (e.g. radio buttons, dropdowns etc.) and instead just displays the values as non-editable text.

I suspect the inclusion of an error in $this->errors is causing some later code in the framework to be skipped.

There is a working example of the UPD3 pattern in "Maintain Menu Controls" which does not exhibit the error you are describing. Try putting an alpha value into a numeric field and press SUBMIT. The screen remains the same but a message is displayed under the field which has the error. If you look at the code in this task you may see what is going wrong in yours.

Thanks for that. My code was originally based on that process but it seems my version was somewhat out of date.

Works perfectly now.
