For a particular very complex grid-like view, I use a factory method to set a
large two-dimensionsal javabean array where each javabean is non-Seam managed
POJO - a description of what to render in that grid:
| @In(required=false)
| @Out(required=false)
| private GridSlot[][] slots;
|
| @Factory("slots")
| public void createSlots() {
| ...
| }
|
I then use facelet methods to iterate across the grid and draw it to the
screen. It all works fine. The problem is I need certain parts of the grid to
redraw based on other grid changes.
Each one of these grid squares contains a h:selectOneMenu like:
| <ui:repeat value="#{slots}" item="row">
| <ui:repeat value="#{row" item="slot">
| <h:selectOneMenu value="#{slot.id}"
valueChangeListener="#{myAction.updateGrid}" onchange="submit()" />
| ...
|
When something in the selection box changes, the form submits correctly and I
get good event values in the updateGrid method. In addition, when the view is
redrawn post submit, the changed slot information is reflected, which makes me
believe that the bijection is working on some level. However, in the
updateGrid method, the local variable "slots" does not actually have updated
properties. I had many theories about why this is happening, but many attempts
to fix this (making the POJO seam managed, playing with injection type, etc.)
haven't changed anything.
