Re: [flexcoders] How much knowledge in Java do you actually need to be hired as a Flex Developer
Hi Fred, As the reasons they ask for Java vary, so does the required level of knowledge... If they are looking for an end-to-end developer they require a pretty solid knowledge of Java. If they are looking for a Flex UI developer with Java knowledge (so you'll have a basic idea on how to integrate with an existing backend), that knowledge can be minimal. There is a 3rd case though, which is pretty common. Since experienced flex developers are in high demand, allot of companies are willing to hire Java developers with minimal flex skills (or beginner Flex developers with Java skills) to train them as Flex developers. In this case, knowing Java tells them that you were able master a structured language and it should be fairly easy for you to learn Flex. I wouldn't go as far as to say that you are screwed. While learning Java would give you an advantage, if you have a solid knowledge of Flex, in most cases, the requirement for Java wouldn't be a deal breaker. Hope this helps, Tibor. www.tiborballai.com fred44455 wrote: How much knowledge in Java do they required?? I mean that's ridiculous , last year there were just a few companies who were requiring some Java Knowledge now 80% of the job ads for Flex Developers (on dice.com) require some Knowledge in java. I understand that it is probably to connect to back end servers. My question is : How much knowledge are we talking about here?? I know nothing about Java. so I guess I am screwed? You end up finishing learning Flex to find out that they require another core technology!! That;'s stupid.

Re: [flexcoders] TabNavigator Problem.
Hi Tejas, What you are seeing is Flex's default history management. You can read about it here: http://livedocs.adobe.com/flex/3/html/help.html?content=deep_linking_8.html To disable it, you can set the TabNavigator's historyManagementEnabled property to false.

Re: [flexcoders] Get Qualified Class Name From String / Dynamically Instantiate Obj
Hi, Unfortunately you can't use getDeffinitionByName without the fully qualified name. However, you can use class aliases. Check out the registerClassAlias http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/net/package.html#registerClassAlias%28%29 and the getClassByAlias http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/net/package.html#getClassByAlias%28%29 methods in the flash.net package http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/net/package.html You can register an alias for all of the classes you'll want to instantiate at runtime based on their name and then instantiate them based on the alias you set. Hope this helps, Tibor. www.tiborballai.com asea19 wrote: I'm trying to instantiate an object based upon it's name. I don't have the fully qualified classpath or an instance of the object.

Re: [flexcoders] Override private ComboBox function
Hi Warren, While the displayDropdown method is private, the methods which call it (downArrowButton_buttonDownHandler keyDownHandler) are both protected.

Re: [flexcoders] Override private ComboBox function
You can simply override the open and close functions as well. (public
override function open():void{ ... ).

Re: [flexcoders] Function to download an image
Hi Christophe, With flash player 10, you have the ability to save files with FileReferrence.

Re: [flexcoders] Passing parameters into Component Item Renderers
Hi Stephen, You can define a static property in your item renderer which you can set to the appropriate value based on who logged in before displaying the table. Or, alternatively, you can use a singleton to define and check who logged in. Tibor. www.tiborballai.com criptopus wrote: I have an item renderer for a column of a table and I want to display the column of the table in a different way independent of the data that is sent to the item renderer. For example if John is logged in I want the column to use two radio buttons and if Pete is logged in I want the column to use tick boxes. I was toying with setting up a public variable inside the item renderer but when and where do I pass the variable in if each row runs separately? Any ideas? - Stephen Brown
Re: [flexcoders] Re: Passing parameters into Component Item Renderers
Yes, you define a static public var allowEdit:Boolean; in your item
renderer.
that variable will be a member of the class, rather then a member of a
specific instance.
Only a single copy of allowEdit exists, regardless of how many instances
of your renderer you have.
Thus, you can get/modify it's value by referring to it using the class name:
MyRendererName.allowEdit=true;
Note, MyRenderName is the class name, not a specific instance!
Once your user logs in, you can set the allowEedit value:
if (username==pete) MyRendererName.allowEdit=true;
inside your renderer, you can refer to the allowEdit property just as if
it was a class member.

Re: [flexcoders] Re: Passing parameters into Component Item Renderers
That depends on weather or not you'll have multiple users logged into the same session. A static member is unique in the scope of a loaded application.
