Carter, note that you most likely do not want to change your list
before the invokeAction() phase.
Think about what would happend if you ask to delete the 3rd entry in
the list you see on screen, but once submitted and before the action
is taken, the liste is reordered/refetched/etc.
The problem come partly from the fact that by default worepetition
use an index to locate your actions (Wonder has a workaround/fix for
this), and partly from the fact that you change a list objects before
action is taken. So if you do not use wonder, avoid changing the
list before any action is taken on it.
I would suggest to filter your list in appendToResponse() before the
call to super.

Carter,
The first question I must ask is if your WOPopupButton is inside
the form you are submitting? If it's not, then it's selected value
will not be submitted by your JavaScript submit.
Assuming that it is, you could rely on the component binding system
by putting your code in the accessor methods for the value bound to
your popup's selection binding. WO will take care of calling these
methods at the proper time during the request-response cycle.
...
...
protected String popupSelection;
public String popupSelection() {
return popupSelection;
}
public void setPopupSelection(String newPopupSelection) {
popuselection = newPopupSelection;
// do whatever you want here WO will take care of calling this
method when the time is right
}
This is just off the top of my head so hopefully it will be useful
to you.

Hi All -
I would like to use a wopopupbutton to limit the
objects that are to be displayed to the the user from
a list/repetition. I have created a default
eofetchspecification that returns a list. I would
then like for the users to be able to pare down the
list by selecting from the wopopupbutton. I am using
onChange = 'this.form.submit()' to reload the page
once a selection is made.
I tried to use awake() and takeValuesFromRequest() but
the popup is still null. The first time that I am able
to get an actual value (instead of null) is during
invokeAction, but I don't want to override this
method.
At what point in the request-response loop will I be
able to use the value that has been selected in the
wopopupbutton to filter my results?
Thanks for the help.
Carter
