Hi, I noticed that a crash occurs when I use multiple FlexTransformManager components in a ViewStack or TabNavigator. Here's the undefined error: undefined at mx.geom::Transform/set matrix()[E] at gs.transform::TransformManager/updateSelection()[src\gs\transform\TransformManager.as:1009] at Function/gs.transform:TransformManager/private:enforceSafetyZone/gs.transform:shiftSelectionScale()[src\gs\transform\TransformManager.as:592] at gs.transform::TransformManager/enforceSafetyZone()[src\gs\transform\TransformManager.as:544] at gs.transform::TransformManager/setOrigin()[src\gs\transform\TransformManager.as:514] at gs.transform::TransformManager/centerOrigin()[src\gs\transform\TransformManager.as:652] It seems related to fetching the transform.matrix in UIComponent. [*]You can easaly replicate this problem by setting up a Flex project (3.6 or 4.6, doesn't matter) [*]Add 2 FlexTransformManager components in a ViewStack or TabNavigator [*]Add an image to both [*]Now you can select the image with the mouse in the first tab, but it will crash when selecting the image in the second tab. Is this a known problem and do you have a solution? For now I'll build a fake viewstack that looks and behaves the same. Cheers, Bart

I'll test this weekend if I can reproduce the problem in a new Flex project.

Hi Jack, I've encountered a bug with the scaleFromCenter property. I'm using the FlexTransformManager in, you guessed it, Flex. Nothing fancy, I just set the property to false. You can view my app here: http://bikewear.j-db.nl/demo5 Steps to reproduce with an image: [*]Upload an image, wait for it (no progressBar yet) [*]Scale the image Steps to reproduce with a TextField (Label component): [*]Type in a text and press the button at the bottom ("Toevoegen") [*]Scale the label The image isn't much of a problem, but when the label is scaled, it animates very strangely. There's not much on my side happening, as you can see: var label:Label = new Label(); label.text = text; manager.addChild(label); manager.selectItem(label);

Hi Jack, I've noticed you have a habit of importing entire packages. I'm not sure what software you use, but when working with Flex, writing out the imports will speed up compiling (when not all classes in a package are used, ofcourse). Compiling my project with full import paths results in about 5 seconds less compiling time. As a favor, underneath are the imports. Also, I was missing event metadata in the FlexTransformManager, which make using your manager a lot easier. So I've added that as well. // ---- FlexTransformManager ---- import flash.display.DisplayObject; import flash.events.Event; import flash.geom.Point; import flash.geom.Rectangle; import flash.utils.getDefinitionByName; import gs.events.TransformEvent; import mx.containers.Canvas; import mx.core.UITextField; [Event(name="move", type="gs.events.TransformEvent")] [Event(name="scale", type="gs.events.TransformEvent")] [Event(name="rotate", type="gs.events.TransformEvent")] [Event(name="select", type="gs.events.TransformEvent")] [Event(name="mouseDown", type="gs.events.TransformEvent")] [Event(name="selectMouseDown", type="gs.events.TransformEvent")] [Event(name="selectMouseUp", type="gs.events.TransformEvent")] [Event(name="delete", type="gs.events.TransformEvent")] [Event(name="selectionChange", type="gs.events.TransformEvent")] [Event(name="deselect", type="gs.events.TransformEvent")] [Event(name="clickOff", type="gs.events.TransformEvent")] [Event(name="update", type="gs.events.TransformEvent")] [Event(name="depthChange", type="gs.events.TransformEvent")] [Event(name="destroy", type="gs.events.TransformEvent")] // ---- TransformManager ---- import flash.display.DisplayObject; import flash.display.DisplayObjectContainer; import flash.display.Graphics; import flash.display.Shape; import flash.display.Sprite; import flash.display.Stage; import flash.events.Event; import flash.events.EventDispatcher; import flash.events.KeyboardEvent; import flash.events.MouseEvent; import flash.geom.Matrix; import flash.geom.Point; import flash.geom.Rectangle; import flash.text.TextField; import flash.ui.Keyboard; import flash.ui.Mouse; import flash.utils.Dictionary; import flash.utils.getDefinitionByName; import gs.events.TransformEvent; import gs.transform.utils.MatrixTools; // ---- TransformItem ---- import flash.display.DisplayObject; import flash.display.Graphics; import flash.display.InteractiveObject; import flash.display.Sprite; import flash.display.Stage; import flash.events.Event; import flash.events.EventDispatcher; import flash.events.MouseEvent; import flash.geom.Matrix; import flash.geom.Point; import flash.geom.Rectangle; import flash.text.TextField; import flash.text.TextFormat; import flash.text.TextLineMetrics; import flash.utils.getDefinitionByName; import gs.events.TransformEvent; import gs.transform.utils.MatrixTools;

Hi Jack, I've been using your TransformManager in Flex. I noticed that the property "arrowKeysMove" was not available from the FlexTransformManager. Even the TransformManager doesn't have a public getter/setter for it. I've added it myself now, but you might want to fix this little bug. Cheers, Mediamonkey
