我真的不知道如何解决这个问题，因为它似乎在裁剪过程中不会发生错误。

你能帮我解决这个问题吗？ 我真的不知道该怎么办。

我使用的是Primefaces 3.5和Myfaces 2.1.17。

非常感谢你。

I really don't know how to solve this because it seems that the error doesn't occur in the process of cropping..

Can you please help me to solve this problem ? I really don't know what to do.

I am using Primefaces 3.5 and Myfaces 2.1.17.

Thank you very much.

It is worth to be mentioned that this entire crop module is embedded in one wizard primefaces step.

最满意答案

我可以在自己的展示中重现它。 当我取消选择图像并单击裁剪时 ，我在ajax响应中看到未处理的异常：

（如果他们安装了一个像样的ajax异常处理程序 ，那么它会很好，所以最终用户可以立即看到它）

嗯，这真是他们自己代码中的一个错误。 这是4天前已被报道为5349号问题 ，目前尚未安排。

如果你真的不能等他们修复它，那么你最好是覆盖渲染器以跳过getConvertedValue()的作业：

public class MyImageCropperRenderer extends ImageCropperRenderer { @Override public Object getConvertedValue(FacesContext context, UIComponent component, Object submittedValue) throws ConverterException { if (submittedValue == null || ((String) submittedValue).endsWith("_0_0")) { return null; } return super.getConvertedValue(context, component, submittedValue); } }

提交的值的格式为x_y_w_h其中_0_0在没有选择任何内容时将为_0_0 。 在这种情况下，上面的自定义渲染器将立即返回null而不是继续转换作业，这将抛出该异常。

要使此渲染器运行，请在faces-config.xml中将其注册如下，其中<renderer-class>是自定义渲染器的FQN：

<render-kit> <renderer> <component-family>org.primefaces.component</component-family> <renderer-type>org.primefaces.component.ImageCropperRenderer</renderer-type> <renderer-class>com.example.MyImageCropperRenderer</renderer-class> </renderer> </render-kit>

I can reproduce it on their own showcase. When I deselect the image and click Crop, then I see the unhandled exception in the ajax response:

(it'd been nice if they installed a decent ajax exception handler, so that this was immediately visible to the enduser)

Well, this is really a bug in their own code. This is 4 days ago already been reported as issue 5349 which is currently unscheduled.

If you really can't wait for them to fix it, then your best is to override the renderer to skip the job in getConvertedValue():

public class MyImageCropperRenderer extends ImageCropperRenderer { @Override public Object getConvertedValue(FacesContext context, UIComponent component, Object submittedValue) throws ConverterException { if (submittedValue == null || ((String) submittedValue).endsWith("_0_0")) { return null; } return super.getConvertedValue(context, component, submittedValue); } }

The submitted value is in the format x_y_w_h wherein the _w_h would be _0_0 when nothing is selected. In that case, the above custom renderer will thus return immediately null instead of continuing the conversion job which would throw that exception.

To get this renderer to run, register it as follows in faces-config.xml wherein the <renderer-class> is the FQN of the custom renderer:

<render-kit> <renderer> <component-family>org.primefaces.component</component-family> <renderer-type>org.primefaces.component.ImageCropperRenderer</renderer-type> <renderer-class>com.example.MyImageCropperRenderer</renderer-class> </renderer> </render-kit>
