    <p>I'm trying to pass the current value of a variable when an a dynamically generated navigation 'node' is clicked. This needs to just be an integer, but it always results in the last node's value.. have tried some different methods to pass the value, a custom event listener, a setter, but I suspect it's a closure problem.. help would be appreciated ;-)</p> <pre><code>function callGrid():void { for (var i:Number = 0; i &lt; my_total; i++) { var gridnode_url = my_grid[i].@gridnode; var news_category= my_grid[i].@category; var newstitle = my_grid[i].@newstitle; var news_content = my_grid[i]..news_content; var news_image = my_grid[i]..news_image; var gridnode_loader = new Loader(); container_mc.addChild(gridnode_loader); container_mc.mouseChildren = false; gridnode_loader.load(new URLRequest(gridnode_url)); gridnode_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, gridLoaded); gridnode_loader.name = i; text_container_mc = new MovieClip(); text_container_mc.x = 0; text_container_mc.mouseEnabled = false; var textY = text_container_mc.y = (my_gridnode_height+18)*y_counter; addChild(text_container_mc); var tf:TextSplash=new TextSplash(newstitle,10,0,4 ); container_mc.addChild(tf); tf.mouseEnabled = false; tf.height = my_gridnode_height; text_container_mc.addChild(tf); var text_container_mc_tween = new Tween(text_container_mc, "alpha", Strong.easeIn, 0,1,0.1, true); gridnode_loader.x = (my_gridnode_width+5) * x_counter; gridnode_loader.y = (my_gridnode_height+15) * y_counter; if (x_counter+1 &lt; columns) { x_counter++; } else { x_counter = 0; y_counter++; } } } function gridLoaded(e:Event):void { var i:uint; var my_gridnode:Loader = Loader(e.target.loader); container_mc.addChild(my_gridnode); _xmlnewstarget = my_gridnode.name; //|||||||||||||||||||||||||||||||||||||||| //when a particular grid node is clicked I need to send the current _xmlnewstarget value to the LoadNewsContent function... //||||||||||||| |||||||||||||||||||||||| my_tweens[Number(my_gridnode.name)]=new Tween(my_gridnode, "alpha", Strong.easeIn, 0,1,0.1, true); my_gridnode.contentLoaderInfo.removeEventListener(Event.COMPLETE, gridLoaded); my_gridnode.addEventListener(MouseEvent.CLICK, loadNewsContent); } function loadNewsContent(e:MouseEvent):void { createNewsContainer(); getXMLNewsTarget(); news_category = my_grid[_xmlnewstarget].@category; var tfnews_category:TextSplash=new TextSplash(news_category,20,16,32,false,false,0xffffff ); tfnews_category.mouseEnabled = false; newstitle = my_grid[_xmlnewstarget].@newstitle; var tftitle:TextSplash=new TextSplash(newstitle,20,70,24,false,false,0x333333 ); news_container_mc.addChild(tftitle); tftitle.mouseEnabled = false; news_content = my_grid[_xmlnewstarget]..news_content; var tfnews_content:TextSplash=new TextSplash(news_content,20,110,20,true,true,0x333333,330); news_container_mc.addChild(tfnews_content); tfnews_content.mouseEnabled = false; news_image = my_grid[_xmlnewstarget].@news_image; loadNewsImage(); addChild(tfnews_category); addChild(tftitle); addChild(tfnews_content); var news_container_mc_tween = new Tween(news_container_mc, "alpha", Strong.easeIn, 0,1,0.3, true); news_container_mc_tween.addEventListener(Event.INIT, newsContentLoaded); } </code></pre>

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.
