I have data coming into flex via a remote AMFPHP object. The data is basically
an array containing generic objects
[0]
date, entry, grade, class, type, db_ID, language etc...
[1]
date, entry, grade, class, type, db_ID, language etc...
...

I want the user to be able to edit individual entries, mark them for update,
delete or insert and then synch with the DB.

The problem:
The user must be able to class the data according to:
=DATE 1
.....=GRADE 1
.........=CLASS 1
.............=TYPE 1
.................ENTRY 1
.................ENTRY 2
.............=TYPE 2
.................ENTRY 1
.................ENTRY 2
.........=CLASS 2
.............=TYPE 1
.................ENTRY 1
.................ENTRY 2
.............=TYPE 2
.................ENTRY 1
.................ENTRY 2

And so on.

Obviously the control the lends itself to this is the AdvancedDataGrid??
However, editing seems tricky since there doesn't seem to be an easy way to ADD
/ Delete entries from the dataprovider. (Keep in mind the source array is first
filtered for the correct dates, then grouped to form the hierarchy).

Right now: ADDING to the DP works, however the entry can't be selected once
it's inserted.
Right now: DELETING to the DP might work, but I can't find a way to insert a
delete button beside each entry.


So, finally, my question is:
Is there a better control that lends itself to this problem? I've thought of
using various comboboxes to allow the user to pick the day, class, subject,
type and then run the filterfunction. However, I can't find a way to traverse
my source data to get a list of the possible values to put into the combo boxes.

Thanks for anyhelp.

May be best to return the data as XML, then you can easily put it in ComboBoxes or ADG. The data format always makes life easy or hard.

Try here:

His example here:

I have use comboboxes before but this should be a good starting place.

Have you issued an itemUpdated() on the collection where the item is?

Just add a property to each object "toDelete" or something, and make an
additional column to hold it. Or you could do something like this:

Recursion is a PIA. You might want to look at this component for an idea of
an approach

Thanks for the help guys.

So am I really better to use XML? I assumed a binary format would be much more
efficient...however I can't stand/understand how flex handles bindings and
multidimentional arrays. I wish it were as simple as PHP multimentional
hash-arrays.

Thanks for the suggestion to use itemUpdated, however it doesn't seem to
change anything. I don't think it's an issue of the arraycollection not knowing
of the changes since the changes should not affect the item's display...I
suspect it has something to do with the ADG's itemRenderers not beeing
generated properly due to the addition of an extra item.

Is it possible that's a problem in your itemRenderer code?
