WO List:
My project has a large monolithic WOComponent that draws a calendar
(WOTable) with the ability to select checkboxes in each day to effect
a change on that day. This has functioned very well for some time now.
But I've decided to try and split this component into multiple
subcomponents in order to address some feature requests that would
make it useful for a plain calendar to be presented alone (without
widgets, buttons, etc.) - for printing for instance.
So, I've created the following 3 subcomponents:
1. DayComponent - presentation of a day with appropriate widgets and
checkbox for selection. Logic is driven by an inner class
CalendarComponent.DayCell
2. CalendarComponent - full month display of DayComponents built using
a WOTable iterated over an array of DayComponent.DayCell objects
3. CalendarPage - user functional page with widgets to interact with
calendar, select individual days on the calendar, and execute actions.
In testing, if I display CalendarComponent and have all my actions
take place there, they work just as they did in the monolithic
approach. So, one level of subcomponent (DayComponent) appears to work
well nested inside CalendarComponent.
However, I don't want all the buttons, etc. on this component - just
an abstraction of the plain calendar. Instead, I want users to be
directed to the CalendarPage (with CalendarComponent embedded) where
all of the buttons etc are presented to take actions on the calendar.
The problem is that I can't figure out how to execute the working
actions in CalendarComponent from this perspective. In one approach to
fixing the problem I moved some of my action methods to the top-level
component and made sure there was a binding for the collection of
DayCells to there (which seems redundant to me). But under that
scenario, those actions continually think that I haven't selected any
day checkboxes.
Mostly, I recognize that my project's best interests are not served
well by my knowledge level so I need that "a-ha" moment to stretch. :-)
It seems to me that ideally I want to be able to do the opposite of
performParentAction() which I have used elsewhere in the project. It
seems to me that I want to be able to execute actions in
CalendarComponent from the parent CalendarPage but it isn't apparent
to me that any solution I've found in my searches fits this design.
Am I approaching this the wrong way or is there a simple way for me to
address actions in a child component using an enclosing form and
widgets that are both resident on the parent?
