flash - Problem with instance names inside Button -

-

I have created a button in Flash, and within it I have a TextField and Movie clip, for example both names set I cover all 4 frames without any keyframe.

I found that I can not use the object using those instance names, so I used this piece of code to see what is happening: 

 < Code> var obj: DisplayObject = this.m_graphics.btnChange.upState; (Var i: int = 0; i & lt; obj.numChildren; i ++) {trace ("we have one object + + + +" + "+ obj.getChildAt (i) +": "+ Obj.getChildAt (my name); var t: TextField = obj.getChildAt (i) as TextField; if (T == blank) is issued; trace ("text field is text" "+ t.text +" ') ;}   
 I get this as output:  
  We have an object 0 - [object shape]: Example 195 with us There is an object - [Object Textfield]: Text is change in the Instance 1999 textfield - Object on 2 - [Object MovieClip]: instance203   
 Because they are TextField and MovieClip, they have their instance name reset to normal "instance ###".  
 Anybody know what the problem is? If I have a movie clip on the button, it works fine (though I have to control the frames myself).  
 I'm going to know about this That I can use to work around it, but it means that many things Seeing this little bit, it looks as if there is no one, the keyframe in the Flash IDE button, Flash creates 4 instances of each item (Tracing through the  upstate  example will give me a  TextField  with the example name "instance2", while  downstat , The name of the example is "instance4"). If I change the text into a state, then it does not reflect in others.  
 I am thinking that when Flash creates objects, it does not copy all the properties correctly (eg name)  
  edit   
 I agree that Shane's answer is an alternative solution - I told myself that I know of different ways to get around the problem - but it neglects the problem, it Does not solve (this is the only reason I do not accept it Receives). I slept in the first place so that nobody knows why this is happening in the first place (TBH, it looks like a bug in the SDK).  
 I also understand the logic behind the argument: "If you want more control, use the Sprite or Movie clip", but I do not agree with it. Flash IDE lets you create buttons with nominated examples inside them, and simple button docs give you access to different states, so this is acceptable for me. If SimpleButton can only be used for very basic, non-floating stationary buttons (also consider localization), then it is very useless. You can use inspiration and movie clips, but then you have to control the different states, which becomes weird. To handle boilerplate I have my button class, but I do not want to re-write the basic SDK functionality, which is why it is a bug for me.  
 I will reward for the time when this is what you are present there. If I do not get anything, then I'll give it to Shane.   
 
 
 This is because the Flash did not receive from the Display.SimpleButton class from  DisplayObjectContainer  , And state containers are not also DisplayObjectContainers:  
 Basically, simple buttons are simpler than their definitions. If you want more complex controls on internal objects, you will need to use Sprite or Movie Clip with the buttonmodet set to correct.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

memcached - Django cache performance -

-
We are now using Redis for in-memory cache for our Django application (we used the first memcatch The difference in performance is no big, and we're using Redis because the disc dump feature). The problem is that Django cache's performance in my view - terrible, we have a view with 102 cache hits (no miss), and it has 81 ms (only the cash part, which is with the DJBugBug toolbar Is measured). In my opinion - this is a very long time, I know, asking for a question for DB can be 10x more (or 100x) time, but that is also not good with cash performance of that fact. We are running radis (and the first memacatch) on different hosts, connected to the local network with other servers. Is there a way to maximize cache performance in Django? Instead of displaying problem cache, there is a possibility of the number of items to be received for each page 102 Cash calls mean long time lost due to network latency. With full control of the code, you may be able to fix it with m...
