I have been following the conversation to a new person here about learning more of Wonder. For me it is an uphill battle. But after quite a while plugging away I have a question (actually two).
I am playing with the ERMDDatePicker. Originally I thought to use my butchered version in my D2W app. From a comment here about examining ERDEditDatePopup, I have decided that I should dodge the bullet and not peruse the DatePicker plan.
I had thought to add a popup to choose the time (limited list). Wrap the popup in an AJAX Observe Field and if the popup changes update the object with the new time.
But after examining ERDEditDatePopup I have decided not to reinvent the wheel and us it instead.
But that leads me to my question(s).
I successfully have my popup version updating the bound object(). However, how do I tell it as an EO so that it is faulted and updates itself on saveChanges(). Meaning, the object() contains my new value, but when I press 'Save' there is no update done. So, WO doesn't know that I changed something.
How do I tell the object that the attribute has changed so do an update on save?
and B:
From reading (over time) and examining many Wonder object, I realize that there are a few methods that one can override as an object is going through its life.
I mean, there are somethings I can do in the constructor, however some of the instance variables are not available yet. takeValuesFromRequest isn't called until later (i don't know exactly when).
Is there a place that lists these methods and when they are called and when I can use (override) them?
