Question

I am using the flex 4 popup manager to popup a panel, but the children of the panel are not staying inside the panel. But when i close the popup the children are being removed.

Like this: (sorry i can’t post pics)

           ----------
           l________l
           l        l
  ..... please enterl
           l--------1

Anybody know why? Here’s my code:

var forgotPopup:Panel = PopUpManager.createPopUp(this, forgottenForm, true) as Panel;
        PopUpManager.centerPopUp(forgotPopup);

And here’s what i’m popping up:

<?xml version="1.0" encoding="utf-8"?>
<s:Panel xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" width="218" height="168" skinClass="PanelSkin" title="Reset Details">


    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>

    <fx:Script>
        <![CDATA[

            import mx.controls.Alert;
            import mx.events.FlexEvent;
            import mx.managers.PopUpManager;

            // Handle the close button and Cancel button.
            private function handleCloseEvent():void {
                PopUpManager.removePopUp(this);
            }

        ]]>
    </fx:Script>

    <mx:Form horizontalCenter="0" verticalCenter="0">
        <mx:FormHeading label="Please enter your e-mail address and your login details will be e-mailed to you"/>
        <mx:FormItem label="E-mail">
            <s:TextInput id="userInput" x="78" y="49"/>
        </mx:FormItem>
        <mx:FormItem direction="horizontal">
            <s:Button id="okButton" label="Submit" skinClass="ButtonSkin" />
            <s:Button id="cancelButton" label="Cancel" skinClass="ButtonSkin"/>
        </mx:FormItem>  
    </mx:Form>

</s:Panel>

Any help on this would be brilliant, thanks.

Try to use the following:

<?xml version="1.0" encoding="utf-8"?>
<s:Panel xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" width="218" height="168" skinClass="PanelSkin" title="Reset Details">


    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>

    <fx:Script>
        <![CDATA[

            import mx.controls.Alert;
            import mx.events.FlexEvent;
            import mx.managers.PopUpManager;

            // Handle the close button and Cancel button.
            private function handleCloseEvent():void {
                PopUpManager.removePopUp(this);
            }

        ]]>
    </fx:Script>

    <mx:Form left="10" right="10" top="10" bottom="10">
        <mx:FormHeading label="Please enter your e-mail address and your login details will be e-mailed to you"/>
        <mx:FormItem label="E-mail">
            <s:TextInput id="userInput" x="78" y="49"/>
        </mx:FormItem>
        <mx:FormItem direction="horizontal">
            <s:Button id="okButton" label="Submit" skinClass="ButtonSkin" />
            <s:Button id="cancelButton" label="Cancel" skinClass="ButtonSkin"/>
        </mx:FormItem>  
    </mx:Form>

</s:Panel>

If you need to have header word wrapped you should reject standard FormHeading and replace it with Label:

<?xml version="1.0" encoding="utf-8"?>
<s:Panel xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" width="218" height="168" skinClass="PanelSkin" title="Reset Details">


    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>

    <fx:Script>
        <![CDATA[

            import mx.controls.Alert;
            import mx.events.FlexEvent;
            import mx.managers.PopUpManager;

            // Handle the close button and Cancel button.
            private function handleCloseEvent():void {
                PopUpManager.removePopUp(this);
            }

        ]]>
    </fx:Script>

    <mx:Form left="10" right="10" top="10" bottom="10">
        <s:Label width="100%" text="Please enter your e-mail address and your login details will be e-mailed to you" fontWeight="bold" />
        <mx:FormItem label="E-mail">
            <s:TextInput id="userInput" x="78" y="49"/>
        </mx:FormItem>
        <mx:FormItem direction="horizontal">
            <s:Button id="okButton" label="Submit" skinClass="ButtonSkin" />
            <s:Button id="cancelButton" label="Cancel" skinClass="ButtonSkin"/>
        </mx:FormItem>  
    </mx:Form>

</s:Panel>

But the best way is to switch to Spark Form which is available since Flex 4.5.
