12.0p: How to save yyyy-MM-dd String from DateItem into field of type text

[Isomorphic]

The methods you tried to override are not marked as valid override points, so it's expected that your breakpoints are not hit. That last (_getValue) isn't even documented, so it wouldn't be valid to call, much less override.

We're not really following the use case here. If you're trying to allow end users to define a default value, why wouldn't you just store that as a date?

Even if you want to store a text value, the value of a DateItem must be a Date, period, it cannot be a text value. If you want to convert from text to date, you need to do it before you try to provide the value to a DateItem.

Hi Isomorphic,

I'm trying to save a date as text to the DB (we have custom fields where the actual value is saved in a field of the correct datatype, but in the GUI I can define a default value for these fields. This default value is stored in a text field. There are nicer designs for sure, but this is what I have) and have problems to get to the following:

• Display select value from DateItem textField as yyyy-MM-dd (working)
• Save it as text yyyy-MM-dd (not working)
• On reload from DB parse it from DB as yyyy-MM-dd (I think it's working)

Do you have any pointers?
I thought I need to @Override DateItem.getValueAsDate(), or perhaps FormItem.getValue(), but this does not seem to work - breakpoints are not hit. The only breakpoint that is it, is the one for _getValue() (with underscore), that is doc'd, but does not have any text. This is what I have so far:

    private class ISODateItem extends DateItem {
        // di.setDateFormatter(DateDisplayFormat.TOSERIALIZEABLEDATE);
        // di.setDisplayFormat(DateDisplayFormat.TOSERIALIZEABLEDATE);
        @Override
        public Object getValue() {
            return super.getValue(); // breakpoint at this line not hit
        }

        @Override
        public Date getValueAsDate() {
            return super.getValueAsDate(); // breakpoint at this line not hit
        }

        @Override
        public Object _getValue() {
            return super._getValue(); // breakpoint at this line [B]is[/B] hit
        }

        public ISODateItem() {
            setEditorValueParser(new FormItemValueParser() {
                @Override
                public Object parseValue(String value, DynamicForm form, FormItem item) {
                    try {
                        DateTimeFormat dateTimeFormat = DateTimeFormat.getFormat("yyyy-MM-dd");
                        return dateTimeFormat.parse(value);
                    } catch (Exception e) {
                        // ignore
                    }
                    return null;
                }
            });

            setEditorValueFormatter(new FormItemValueFormatter() {
                @Override
                public String formatValue(Object value, Record record, DynamicForm form, FormItem item) {
                    DateTimeFormat dateTimeFormat = DateTimeFormat.getFormat("yyyy-MM-dd");
                    return dateTimeFormat.format((Date) value);
                }
            });
        }
    }

Thank you & Best regards
