I have a flex app that takes data from a back end database then displays the content in one of 3 views. These views are all in a viewstack which is instantiated in main.mxml The method to get the data (remote object)is also in main.mxml.
The views rely on the data so how can I go about making sure that the data is loaded first before any of the views in viewstack are created / initialised to stop me having null reference errors?
need to load 10 records from database in advanced data grid. After i scroll the advanced data grid. it has to load 11 to 20 records etc.
View 1 RepliesI'm currently working on a project that contains a lot of data, about 14.000 records. This means an xml file of about 3mb. Now my question is: Should I use the xml file to load all the data at once, or should I use a webservice, that provides the data when I need it? Keep in mind that I'm new to webservices. And if I'm going to use a webservice: How do I store the data, in a mySQL database?How fast is a webservice?
View 1 RepliesLoad data on demand (lazy load data ) for groups in advanced data grid control.When the user expands a node the flex component can make a webservice calla and retrieve data for this group.
ignoring the webservie part, I am trying to figureout how to do the UI part in AdvancedDataGrid ?
I want to use an HTTPService to load some data (number of columns and number of rows) which change randomly by a certain frequency I get the string like freq#ncols#nrows#value. How can i display for example: 1000#21#13#2391 that means: in 21 col, 13 row i have the value of 2391 which changes every 1 second.
View 1 RepliesI have generated a service call to a service called ServiceName.getService() - I can successfully pull data displayed inside mxml layout elements, but, instead of displaying it, I just want to assign it to a global.
I always get an error on the second line below - apparently the value has not been fetched yet. I have also tried adding a listener, and setting the global value on COMPLETE, but that is apparently never called. (I am guessing this generated service call stuff does not actually trigger a COMPLETE?)
Short question is: how do you simply assign a variable after you have loaded it via a service data call. (Not just HTTP)
getServiceResult.token=ServiceName.getService();
GlobalVars.variablename = getServiceResult.lastResult.variablename;
I get the below error when i am trying to make a java call from flex.

Im new to placing external data into Flash. I just got CS3 and Im trying to use Flash to dynamically load XML data via a FlashVars call in the HTML.
The problem is I have followed the very straight forward AS2 Help files for using FlashVars and URL variables.I have placed the code directly from the Help file into the Html between
<noscript> <noscript>and i keep getting undefined.I have tried saving the file as flash 8 and i am publish flash 8.
We have implemented a Flash photo slideshow on our site and it works just fine for most of our users. Whenever the xml.load(success) returns false I have the Flash email me a debug report. For the life of me I can not find a common thread between all of these people having problems with the Flash. I don't think it's a cross-domain issue because it works for most people, and I have the crossdomain.xml files where they should be.

I have an Access Database (doesn't need to be Access, I can phpAdmin or mysql, whatever will work) that has a list of names. I want the user to open a Flash form and have the names load up into seperate input boxes for each name. The user can then change the names, move them, whatever, and then save the record. I want it to just overwrite the record. I donlt want create a new record. I cannot, for the life of me, figure this out. I have tried to find some tutorials but nothing makes sense. Is ASP a good way to go? I have been struggling with this for a week now.
View 3 RepliesI currently have a Flash app that gets populated by parsing data from an external XML file. However, I need to get the XML data into a (JSP) session and can't neccesarily have an external XML file--any suggestions? Can I put the XML string into a hidden input field in a form on the HTML? Can Flash communicate with that HTML? Or are one of the below methods recommended:
* FlashVars
* Flash Remoting
* Web services
* JavaScript - call JS function
* fscommand
* ExternalInterface
i load in AS3 data into flash and mantain their data type? Like receiving an array and even with arrays in it and recognizing that is an array instead of a standard string.
And if this is possible is it more reliable then using XML?
is there a way to clear an XML object of its data to allow it to load new data from the same URL?

In flex 3 I have a hierarchical data structure. I would like to display the content of it in a tree. My problem is that I have nodes which data calculated from children nodes. How to structure the hierarchy to make automatic changes to those parent nodes, if their children's data changed? For example:
Every node has a warning flag. If some of the children warning flag changed to true, then the parent warning flag should change automatically set to true. A node integer field is the sum of the children integer fields, and if any of the children changes, the parent integer field "calculates" the sum immediately. Is there an easy solution wit good structuring changes happen automatically, or I have to make some custom functions?
I have to populate an Advanced Data Grid which have the following fields: Continent->State->Society-->Actual Value-->Estimate Value I want to simulate a financial market so i have to change some of the values by asynchronous request from an HTTPService; If necessary i'll post the .as file, but it is generated automatically by Flex Builder.

I've got a Gridcolumn in a Datagrid (Spark). The Column's dataprovider is a Number value that gets updated via Binding.Now, without an item renderer the cell displays the correct values.If I set an item renderer, I can't access the values in this renderer.My renderer looks like this, so nothing really do here (for now) but to trace the value, but the value is always NaN.
<?xml version="1.0" encoding="utf-8"?>
<s:GridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" width="100%" height="100%" >[code].......
without the renderer, the column displays the correct values, so apparently the DefaultGridItemRenderer works fine.As requested, here is my Datagrid;
<s:DataGrid id="dataGrid" dataProvider="{_listItems}">

_listItems is an ArrayList with instances of a model class, which has (amongst others) a property called change of type Number.
I have been goggling a lot to find anything with link-based data visualization in Flex 4. something like below screen shoot (made using Ravis). Where user can drag these nodes, without removing the links and on double click of any node we can set some properties for that particular node. I found this Ravis (Birdeye), but not much of examples and support is available for that.

I have an xml file (externally saved) that is similar to the following:
[root]
[main]
[title]...[/title]
[Code]....
What I like to do is to get what's in [title] tag using HTTPservice, import it into Flex, and save it as array objects, and do the same thing for [content]. This way I can later refer the array object saying title[0] or content[2].
I have a DataGrid whose dataProvider is an Array of int Arrays (each with different lengths). Since each row has variable size (and I want to display all the data), I decided to extend DataGridColumn and overwrite the itemToLabel function to be able to display the data. The problem is that I also need to display the data differently depending on the int value.
I believe the only solution is to write an itemRenderer, but the only input the itemRenderer.set(data) function receives is the entire int Array. I believe I need either the exact string returned by itemToLabel or the column index of the cell the itemRenderer is for (to basically do the same parsing I implemented in itemToLabel).
I am trying to drag and drop hierarchical data in the same advanced data grid, and I would like the data provider to updated when the ADG is updated. (I want to be able to save and load this tree, so it is important that drags and drops are saved.)
[URL]
The sample app has an ADG showing hierarchical data as well as flat data. The first column of each datagrid shows the rowindex of the underlying data.
If you rearrange the items on the left ADG, the row indexes become unordered. If you click traceTree you see that the data provider is not in order.
On the other hand if you do the same on the right, the row numbers stay ordered even when the objects move around and if you click traceFlat, the data provider is in the order shown on ADG
My goal is to have the data provider order match the ADG order for the left grid which is displaying hierarchical data.
