Dynamically change height of TileList

You have to adjust rowCount of Tile List to make height according to data at runtime. In below example if column count is 1 you rowCount="data.length()". Now data can be XML children.length() or array.length or any data length.

[mx:TileList id="_videoList" rowCount="{data.length()}" updateComplete="changeHeight"]

You can also updateComplete if you have column count more than 1.

private function chanegHeight():void{
var rc:int = Math.ceil(data.length() / _videoList.columnCount);
if (_videoList.rowCount!=rc) _videoList.rowCount = rc;
}

XML error while connecting Flex 4 to Java using BlazeDS 4 in Flash Builder

You might face of the following error while creating data service using BlazeDS.

=========================
ERROR: XML parse error: Error on line 1 of document: cvc-elt.1: Can not find the declaration of element ‘model’. Nested exception: Can not find the declaration of element ‘model’.
=========================

In that case make sure you download latest BlazeDS 4 nightly build. Once you unzip the file you will get war file. Just dump that with different name under Tomcat/weapps directory. You have to copy files from lib directory into existing application webapps//WEB-INF/lib directory.

Building Flex 4 application for BlazeDS 4 Remoting destinations using Flash Builder 4

Everybody knows Flex 4 has great features like connecting to different backend using BlazeDS or PHP, ColdFusion, LCDS or HTTPService/Web Service.

Now you can create Flex 4 UI without doing single line of code. First you have to get the following software

1. Flash Builder 4
2. BlazeDS 4 or nightly build is fine
3. MySQL server
4. Create schema and table.
5. Create Java Class to get data from MySQL. Also create public method with return type as List(Object) so you can bind them to Flex DataGrid easily.
6. JDK 1.6 installed.
7. Tomcat 6 installed.

Please note you will have more complex things to do in real life so just take above as exercise.

1. Create Flex Project in Flash Builder and select J2EE as backend and select BlazeDS.

2. Setting BlazeDS 4.
After you copy your blazeDS.war into tomcat/webapps directory go to webapps//web.xml and make changes to RDSServlet part as following

{param-value}false{/param-value}

3. You have to set your destination in tomcat/webapps//flex/remote-config.xml

Please make sure you have Java class name in tomcat/webapps//WEB-INF/classes directory.

4. Select "Data" --> "BlazeDS" from Menu option of Flash Builder. In new window it will show you destination name i.e. {servicename} from step 3. Click on checkbox next to it and click on "Finish" button.


5. After that drag DataGrid component in Flex Project using Component view. Still in Component view right click on DataGrid and select "Binding Data" option. It will prompt you to select service and method name. If you have more than one method select one you want more combobox.

After that everything is done by Flash Builder.

RUN You application to see data populated in datagrid without single line of coding in Flex 4.

You can also create free form i.e. (mx:Form) for the same method call on destination. If you have method call findAll() for users or anything else it will create form with option to hand pick required field for edit, update or delete operation.


Enjoy,

Migrating from Flex 3 to Flex 4

One of the simple trick and very important one is to add following line in Flex compiler. Right click on Flex project name from Flex 4 & select "Properties" option (last one). In open window click on "Flex Compiler" and following line at the end.

-compatibility-version=3.0

After that compile your application and you can see Flex 3 apps migrated or compiled in Flex 4.

If you have CSS issues at this line in your Flex code.



@namespace "http://www.adobe.com/2006/mxml";



PS: Adobe is going to release Flex 4 sometime end of March 2010 or April 2010, so it almost about the time you should to start thinking of converting your existing Flex 3 apps into Flex 4.

Flex 4 has simplified State declaration and make it very easy to implement. I think it is worth the efforts to convert even if your existing one works fine.
