小编los*_*and的帖子

我正在捕捉一个KeyPress-Event以检查某些允许的值.为了能够删除我在实际检查之前使用以下代码

if (e.KeyChar == (char)Keys.Delete || e.KeyChar == (char)Keys.Back)
{
   return;
}
...actual check for only digits or whatever

问题是,当我按下键盘上的句号时,e.KeyChar ==(char)Keys.Delete也是如此.

怎么会这样？我能做些什么呢？

谢谢

我必须将datarows绑定到我的控件.到现在为止还挺好.现在的问题是,我的数据行只包含我必须绑定的列中的字符串,但当然"检查"Checkbox的属性只接受布尔参数.

有没有办法在这里使用DataBinding？也许两者之间有某种转换器？

谢谢

为了与Wuala同步我的存储库,我创建了一个新的裸存储库(已同步).我将这个作为遥控器添加到我现有的(本地)仓库中.

现在我意识到,git status当我超越遥控器时,也应该告诉我,但它不是!

C:\Users\blubb\Git Lokal\myproject>git remote -v
wuala   file:///C:\Users\blubb\Git\myproject-remote (fetch)
wuala   file:///C:\Users\blubb\Git\myproject-remote (push)

目前我知道我的lokal repo位于遥控器之前(本地更改被提交),但这是我得到的状态.

C:\Users\blubb\Git Lokal\myproject>git status
# On branch master
nothing to commit (working directory clean)

我可以推动我的更改但是很高兴看到我提前完成了多少次提交rebase squash.

我想在应该支持Java 8的最新Apache-Karaf版本（3.0.2）中使用Java 8功能。

我的域层（存储库）中有一个服务接口，该接口具有用于生成身份的默认方法

public interface MyRepository{

    ...

    default MyId nextIdentity() {
        return new MyId(UUID.randomUUID().toString().toUpperCase());
    }
}

然后，我有了该接口的实现，该接口使用Blueprint（Apache-Aries）作为OSGi-Service公开。

当我运行我的应用程序时，捆绑包安装成功，服务被注册，但是当应用程序层调用nextIdentity方法时，我得到一个异常。

IncompatibleClassChangeError: Found interface MyRepository, but class was expected

应用层很简单：Interface-Attribute通过Blueprint注入其类（在本例中为OSGi-Service-Reference）。

我确实检查了编译：所有模块都在Eclipse中使用Java 8符合性级别进行了编译。我猜测问题与不是Java 8的aries-proxy有关，但由于karaf支持。

编辑：添加了Stacktrace
