Flex :: Cache Variables In Dataprovider?
Jan 5, 2012
I've got a model class with a bunch of Number variables that change frequently. They all dispatch their custom events, thus are bindable. In my UI, a couple of those class instances are bundled into an ArrayList that serves as the dataprovider for a Spark DataGrid. The class variables change perfectly fine, so problem there.
What I'd like to do now is to change the color formatting of those numbers (the corresponding labels in the gridcoloums to be exact) depending on the data that comes in, so to say change in green when the new value is bigger, change to red when the new value is smaller than the old one.

The flex DataGrid colums are arranged alphabetically by default. I need to order the DataGrid colums as per the order in its dataProvider. The dataprovider is the result of the HTTPService . And the number of columns is not known to us . The number of columns depends on the HTTPService result.

I am writing a Flex application for use on a private intranet with no external Internet access. I want to use Google's 3D Maps Flex API, but it must be connected to the internet to download map tiles on demand.
Is there a way to locally cache the 3D map tiles and data so that I can run this app without an internet connection? And if not, is there a 3D GIS that supports Flex integration and allows for a local map cache?

I am creating the standard "Click to add row" control but I really don't want to dirty the dataProvider with a "placeholder" since it is bound to the model and could end up in the database. Is there a way to add a row that isn't represented in the dataProvider? I started down the road of adding an item directly to listItems but then that needed an item in rowInfo and then that need a reference in rowMap.

[Code]...
I tried using an array of objects as a dataprovider. The item renderer works and the horizontallist behaves as I expect it to. However, when I use an xml file, it's empty.... I don't know why it's not working.

I have a project that was compiled with the Flex 3.2 SDK. One of my components is a combobox, which is bound to a property (called products) in the Cairngorm model. If I insert a new value into model.products, then the combobox immediately shows the new value. Works perfectly.
I then moved to the 3.5 SDK, and running the identical operation causes a problem. Even though the model has been updated (I have verified that this is definately the case), the combobox does not show the new value correctly - it seems to be aware that there is a new item because there is a new row in the combo, but the new row is blank and unselectable. The existing items in the combo are there and selectable (as they should be). If I re-initialising the form (i.e. close and re-open the TitleWindow on which the combo is located), then all the correct values (including the new one) are shown in the combo.
I have swapped back and forth a few times between 3.2 and 3.5 to verify that this is indeed the root cause.

What I would like to do is simply add to a dataProvider, but when I do, I get an error. Here's the code I'm trying to run...
dg.dataProvider.addItem(obj.ResultSet.Result[i]);
It's inside a for loop, using i as the integer. It works great doing...dg.dataProvider = obj.ResultSet.Result But that won't work for me, because I need to add to the dataprovider more than once. I'm getting results in batches of 10, and I need to add each batch to the dataProvider when it's received. I also tried to to do...
var dgDP:dataProvider = new dataProvider(); But for some reason Flex doesn't recognize it...

I'm implementing some kind of combobox control (by extending spark.components.supportClasses.DropDownListBase)
Now, inside this control; I need to know:
If the dataprovider is changed/assigned. (which I can do... the first approach below works); if any item in the dataprovider collection has changed.
I tried 2 methods that did not do the trick...
1ST APPROACH:
2ND APPROACH:
UPDATE: Edited above.. The first approach lets me know if the dataprovider is changed but not if any item is updated in the dataprovider collection. The second approach does not work at all..

I have a list object and I'm adding items to it with addItem through the dataProvider.Before adding an item to the list I want to make sure it's not a duplicate. I've tried using indexOf on the dataProvider and it returns null. I've tried casting it to an array and it works, but always returns -1 even if the element exists in the dataProvider.The only method I've been able to use seems a little hacky and I'd like to know if there is a better way to find an element in a dataProvider.

the dataProvider 'data' updated itself every 3 seconds, so every 3 seconds that is a flicker of some sort, i see for a really short time an empty area and then it gets redrawn again. is there a way to make the update somewhat faster ?

I've got a couple trees that I allow a user to drag and drop from one to another, works great except one apparent limitation. I'm picking up where they drop it in the list and adding it to the dataProvider manually. The user can drop it everywhere except after the last child of any particular node it seems, since it reads that position as being between the node and it's next sibling.
It seems the best way to deal with this is to add something like a dummy leaf so the user has something to drop the item in front of. I don't want this leaf in the dataProvider, so is it possible to add a leaf (or a folder) to the tree without adding it to the dataProvider?

I'm using a List which I need to be empty at the start. I'm adding items to it as needed by clicking a button. Since it's empty, I haven't added a dataProvider property
<s:List id="thelist" itemRenderer="listIR" />
To add an item, I'm adding it to the dataProvider directly
thelist.dataProvider.addItem()
but when I do that, it gives me this error
#1009: Cannot access a property or method of a null object reference.
Also I have a debugging Alert in the listIR itemRenderer itself and I see that when the list is created, I get that alert twice as if 2 itemRenderers were created, even though the list is supposed to be empty at the start.
How do I start with an empty dataProvider and add items smoothly to it?
