我的RCP應用程序出現問題。RCP應用程序活動
首先，我在plugin.xml中定義的活動：
<extension
point="org.eclipse.ui.activities">
<activity
id="myproject.view.input.activity"
name="myproject.view.input.activity">
<enabledWhen>
<with
variable="myproject.view.input.active">
<equals
value="ENABLED">
</equals>
</with>
</enabledWhen>
</activity>
<activityPatternBinding
activityId="myproject.view.input.activity"
pattern="myproject.gui/myproject.view.input">
</activityPatternBinding>
然後我定義我的SourceProvider：
<extension
point="org.eclipse.ui.services">
<sourceProvider
provider="myproject.util.CommandState">
<variable
name="myproject.view.input.active"
priorityLevel="workbench">
</variable>
最後，我CommandState類：
public class CommandState extends AbstractSourceProvider {
public final static String OUTPUT_VIEW = "myproject.view.input.active";
// then goes some others variables, i just skip them
// ....
public final static String [] ACTIONS = {OUTPUT_VIEW /*and all others variables*/};
public final static String ENABLED = "ENABLED";
public final static String DISENABLED = "DISENABLED";
private final Map <String, String> currentState = new HashMap <String, String>();
@Override
public void dispose() {
}
@Override
public String[] getProvidedSourceNames() {
return ACTIONS;
}
@Override
public Map <String, String> getCurrentState() {
return currentState;
}
public void setEnabled(boolean enabled, String [] commands) {
String value = enabled ? ENABLED : DISENABLED;
for (String command : commands) {
currentState.put(command, value);
fireSourceChanged(ISources.WORKBENCH, command, value);
}
}
}
在我的登錄窗口中，應用程序檢查用戶權限，並啓用或禁用視圖，命令等與se CommandState的tEnabled方法。對於命令它工作正常，他們正在啓用或禁用正確（我禁用他們以其他方式，但它工作正常，即使我禁用他們通過活動，以我所述的相同方式）。但是，當我嘗試禁用視圖和開放的角度來看，包含視圖（myproject.view.input），它會打開沒有這一觀點，而且還拋出異常：

我試圖調試我的申請，前打開我的觀點whith那視圖，我檢查了我的CommandState源提供程序的currentState，並且所有圖片都可以：所有變量值都正確並且myproject.view.input.active = DISABLED
任何人都可以說，爲什麼會拋出異常？感謝您的任何幫助，或任何想法。對不起，大柱和髒話
*編輯：添加了完整的堆棧跟蹤
聽起來不像它與活動定義有任何關係。我們需要stacktrace以獲得進一步的幫助... –
