flex/flashbuilder 4 浓汤状态有时为空白

发布于 2024-10-03 11:29:30 字数 1143 浏览 3 评论 0原文

下面是一个非常简单的示例，随机地，如果我单击第 2 步按钮，状态将发生变化，但第 2 步面板不会出现。

我怀疑由于某种原因没有创建状态的子级，这就是为什么我将 itemCreationPolicy 设置为“立即”，但这没有什么区别

这对应用程序来说是灾难性的，因为用户陷入困境并被迫刷新

有什么想法吗？

 <s:BorderContainer xmlns:fx="http://ns.adobe.com/mxml/2009" 
                       xmlns:s="library://ns.adobe.com/flex/spark" 
                       xmlns:mx="library://ns.adobe.com/flex/mx" 
                       creationPolicy="all" currentState="step1">   
        <s:states>
            <s:State name="step1"/>
            <s:State name="step2"/>
        </s:states>
        <s:BorderContainer includeIn="step1" itemCreationPolicy="immediate">
            <s:Panel title="Step 1"/>  
        </s:BorderContainer>
        <s:BorderContainer includeIn="step2" itemCreationPolicy="immediate">
            <s:Panel title="Step 2"/>  
        </s:BorderContainer>
        <s:Button title="step1" click="{this.setCurrentState('step1',true)}"/>
        <s:Button title="step2" click="{this.setCurrentState('step2',true)}"/>
    </s:BorderContainer>

原文

Below is a very simple example, randomly, if I click the step2 button the state will change but the Step 2 panel will not be there.

I suspect the children of the state are not getting created for some reason, which is why I set the itemCreationPolicy to "immediate", but it makes no difference

This is catastrophic for the application because the user is left in limbo and is forced to refresh

Any ideas, please?

                       xmlns:mx="library://ns.adobe.com/flex/mx" 
                       creationPolicy="all" currentState="step1">   
        <s:states>
            <s:State name="step1"/>
            <s:State name="step2"/>
        </s:states>
        <s:BorderContainer includeIn="step1" itemCreationPolicy="immediate">
            <s:Panel title="Step 1"/>  
        </s:BorderContainer>
        <s:BorderContainer includeIn="step2" itemCreationPolicy="immediate">
            <s:Panel title="Step 2"/>  
        </s:BorderContainer>
        <s:Button title="step1" click="{this.setCurrentState('step1',true)}"/>
        <s:Button title="step2" click="{this.setCurrentState('step2',true)}"/>
    </s:BorderContainer>

我刚刚使用 Flex SDK 4.1 对其进行了测试，它可以在不更改创建策略的情况下工作。单击“步骤 2”成功更改状态。

顺便说一句：您不需要在单击事件处理程序中使用花括号...

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/mx" currentState="step1">

    <s:layout>
        <s:VerticalLayout/>
    </s:layout>

    <s:states>
        <s:State name="step1"/>
        <s:State name="step2"/>
    </s:states>

    <s:BorderContainer includeIn="step1">
        <s:Panel title="Step 1"/>
    </s:BorderContainer>

    <s:BorderContainer includeIn="step2">
        <s:Panel title="Step 2"/>
    </s:BorderContainer>

    <s:Button label="step1" click="setCurrentState('step1', true)"/>
    <s:Button label="step2" click="setCurrentState('step2', true)"/>
</s:Application>

I've just tested it with Flex SDK 4.1 and it works without changing the creation policy. Clicking "step 2" successfully changes the state.

BTW: You don't need the curly braces in you click event handler...

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/mx" currentState="step1">

    <s:layout>
        <s:VerticalLayout/>
    </s:layout>

    <s:states>
        <s:State name="step1"/>
        <s:State name="step2"/>
    </s:states>

    <s:BorderContainer includeIn="step1">
        <s:Panel title="Step 1"/>
    </s:BorderContainer>

    <s:BorderContainer includeIn="step2">
        <s:Panel title="Step 2"/>
    </s:BorderContainer>

    <s:Button label="step1" click="setCurrentState('step1', true)"/>
    <s:Button label="step2" click="setCurrentState('step2', true)"/>
</s:Application>
