I would like to know how to delete(clear) the existing list data values before binding new values. I'm using the list for binding data dynamically using http services. When I make a new call to the service, I want the exiting items to be flushed and bind the newly retrieved data to the same list. How can I achieve this?
View 2 RepliesI'm working on a game whose background has many layers that each scroll at different speeds.
Inside each layer I have a Sprite, I've started using graphics.beginBitmapFill, but what I've found is that the graphics.clear() function doesn't actually clear the contents set by the previous call to graphics.begin.BitmapFill. Each frame, I adjust the matrix to shift the layer as needed. Then, I call graphics.clear() and graphics.beginBitmapFill() with the adjusted matrix. Since my layers have alphas in the bitmap, I can see the contents that was drawn the previous frame.
I'm developing a mobile AIR application using IntelliJ.
When debugging in Flash Builder there is an option to clear to application data on each (debug) launch of the ADL (see screenshot below) However, I can't find this setting in IntelliJ or some ADL parameter to force a clear on each new debug session. I was wondering if such an option exist in IntelliJ or ADL.
A little background: I'm using the PersistanceManager in the application to store some user settings and I want to be able to start the application without the saved settings from my previous run. Using this setting in Flash Builder does the trick, but I'm having no luck with IntelliJ.
It is very simple to retrieve data from a database and display it inside a DataGrid. However, what are the current practices to push the changes in the DataGrid back to the database? One can achieve this by inserting a lot of meta information, however, it is very tedious and not reusable.
View 4 RepliesI am acquiring the contents of a table to fill a dropdown box in a Flex 3 application:
<mx:ComboBox dataSource="{myList}" />
The list is populated by the contents of a database table of persons:

The combo box, however, also needs to have some other meta-entries in it that do not come from the database:

I am using a List with an ArrayCollection as a DataProvider. The list uses ComboBox as Item Renderer itemRenderer="mx.controls.CheckBox"I would like to bind the values in the List.You have a list with several comboboxes, and those values are loaded dynamically from an ArrayCollection.The ArrayCollection contains Objects with a boolean property for which I should bind the True/False values selected in the comboboxes.

Environment: Flex/As3/Cairgorm/composite component.I have two comboboxes and two datagrids such that the selection of combobox 1, inserts data into combobox two and the fist datagrid.The selection of combobox 2 inserts data into datagrid 2.I have setup the change event so that the user selection on each of the combo boxes do the right thing. The problem is that on the initial load of the comboboxes, the change event does not fire and subsequent synchronization data loading does not happen.Is there an event for getting the itemselected (1st item) after the combobox is initialized?

I would like to go over all the questions (there are more than question1,question2 and question3). some of those contain numbers (salary, bouns) and some don't. I am looking for a way to go over the whole list, querying if the answer is a number or not, and if so - get the number. (and do some calculation with it).
Is there any way that I can clear all of the previously added items within a List?

I'm working on a flash cards application and am using an ArrayCollection of Objects to store each cards individual data. When the user click the 'save' button, the text from the two textAreas and the 'title' textinput are stored in the AC as one object with .title, .side1 and .side2 properties that contain the text from the flash card. I have made a List in a separate class I want to have display the title of each card the user has created, but after days of researching and looking around, I still cannot get the display to list the titles.
Part of my NewCard.mxml:

View 1 RepliesI have a TileList which represents some remote data. I also have a form which allows me to change the data. And the data may be changed by someone else too.
What is the best way to maintain data in the list in an up-to-date state? The simplest option I see is the following:
Select an item in the list Edit it in the form Save it. The form submits the data to the server When the server reports success the list re-fetches it's data The very bad thing about this workflow is that the list loses selection (a tree would also loose the nodes' expanded/collapsed state). I would really love to find out another option which would enable the list to maintain it's selection state.

I need to detect when a Flex Spark List (spark.components.List) data has changed so that I can programmatically change its scrollbar. I know that List is a an EventDispatcher but it's unclear which event I'd register for.
Edit: My List's dataProvider is an ArrayCollection that elements are added too. So the dataProvider is never replaced. I considered listening to the backing ArrayCollection, but it's possible the List will react to the change after my listener, which alters the scrollbar. Thus my listener's changes will be superseded by that of the List.

I have a Spark List (spark.components.List) backed by an ArrayCollection for its dataProvider. The List has a vertical scrollbar when there's too many rows to display. What I want is when a new row is added to the List for it to scroll to the bottom to show that new row.
I've tried calling List's ensureIndexIsVisible from a listener on the ArrayCollection. This doesn't work because the List hasn't yet fully rendered the new row. It will either scroll to the second from the last row, or throw the exception:
