    <p>yes, the loop increment variable is in the scope of the loops parent, not inside the loop itself. This is intentional, for examples like this:</p> <pre><code>public function getPositionOfValue ( value:String ) : int { for ( var i:int = 0; i &lt; someArray; i++ ) { if (someArray[i] == value ) { break; } } return i; } </code></pre> <p>this allows you to access the value of i once the loop is over. There are lots of cases where this is very useful.</p> <p>What you should do in the cases where you have multiple loops inside the same scope is var the i outside of the loops:</p> <pre><code>public function getPositionOfValue ( value:String ) : int { var i:int; for ( i = 0; i &lt; 15; i++ ) { //do something } for ( i = 0; i &lt; 29; i++ ) { //do something else } return i; } </code></pre> <p>then you get rid of your warning. The other thing to consider is to name your loop increment variables something more descriptive.</p> <p>Update: Two other things to consider:</p> <p><s>1) you shouldn't use uints except for things like colors and places where Flex expects a uint. They are slower than int's to use.

You can get some hard to track down bugs if you dont. </p>

    1. COThank you for the meaningful answer. :) BTW: 1) I didn't know that `uint` is slower. Thanks, it may help me in the future. 2) I know, but I've read that if an `int` or `uint` is uninitialized, its value is always 0.

    2. COno problem, glad to help. Re: your response to 2), thats right, but if you var your i outside of the loops, your second loop is going to have the value of the previous loop now. so be careful. In my experience, its always better to be explicit.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
