I stand corrected. A purist would argue that
you should figure out why the row heights aren't working, but I'm with you; if
it works, and gets done quickly, who cares?

intersting to read this. we are working on a datagrid that
has complex data, two text fields, in one column. We used a custom
itemEditor with a RTE in it. Nice, right? nope, sucked. Can't quite
seem to get the row height to expand contract as needed. So, we went with
a modal popup.

were really valuble in Flex 1.5. Most didn't know about the depth

great for putting stuff "above everything"

Nowadays, with states and the DisplayList, the
only valid reason I can see
is modality.
Thus, I'd avoid 'em like
the plague unless you can answer yes to the
following question: "Does the
form need to be modal?".

Cairngorm: Managing Popup Windows
I've done some research on this
list but haven't found any valid
information on what's considered best
pratice in dealing with popup
windows. The few Cairngorm sample apps that
are around don't seem to
use the TitleWindow component at all.
Let's
say I have a simple DataGrid populated with some user data. If I
click on a
row in the DataGrid a popup window opens with a form for
editing the user
information. The popup window also has two buttons
for deleting or saving
(updating) the user account.
I have done stuff like this several times
in Flash/AS2 but I've never
used a framework approach so far. Now, if I
look at this rather simple
task from a Cairngorm perspective it doesn't
seem to be that simple
any more. (But I guess that's because I'm not yet
too familiar with
Cairngorm.) I know how to establish databinding between
the data
provider and { model.users} and all this basic Cairngorm
stuff.
But what happens when a row is clicked? I'm not even sure if
I'm
supposed to treat this event as a single event ("selectUser"
or
"openPopup"?) or as a chain of two events ("selectUser" ->
"openPopup"). Since my user information is organized as an array
of
value objects it's easy to assign the selected user VO
to
model.selectedUser:
model.selectedUser =
UserVO(userList.selectedItem );
But am I "allowed" to directly access
the ModelLocator from my view
component? Or am I supposed to route this
simple action through the
Cairngorm "command chain" (Cairngorm Event ->
Front Controller ->
Command Class -> ModelLocator)?
Next
question, what about the popup itself? Can I simply
use
PopUpManager.createPopUp( this, UserFormView , true)? Or am I
supposed
to treat this as a Cairngorm Event, too?
I feel in "safe
Cairngorm terrain" again with the "updateUser" and
"deleteUser" actions on
the buttons. But what about closing the popup
window? Is this even worth a
Cairngorm event?
I guess these questions sound rather stupid to those
of you who are
more experienced with frameworks. But at the moment these
questions
are obstacles on my way to master Cairngorm (which I will
hopefully do
one day). I apologize for my verbose post and my bad English,
but I
hope that someone can shed some light on these
issues.
