我打开了一个如下所示的模式
Map<String, List<String>> paramMap = new HashMap<String, List<String>>();
Map<String, Object> options = new HashMap<String, Object>();
options.put("modal", true);
options.put("width", 650);
options.put("height", "100%");
options.put("closable", false);
options.put("draggable", false);
options.put("resizable", false);
options.put("contentWidth", 645);
options.put("contentHeight", "100%");
List<String> idValues = new ArrayList<String>();
idValues.add(idValue);
paramMap.put("id", idValues);
getRequestContext().openDialog("sampleModel", options, paramMap);
and the nagivation case for the model is as follows
<navigation-case>
<from-outcome>sampleModel</from-outcome>
<to-view-id>/sample/views/model/sampleModel.xhtml</to-view-id>
<redirect include-view-params="true" />
</navigation-case>
一切都按预期工作，但是当我尝试关闭以下模式时
RequestContext.getCurrentInstance().closeDialog("sampleModel");
上面的代码抛出异常 异常：java.lang.NullPointerException：参数错误：参数键为空

有人可以帮忙解决此问题并从bean中关闭模式吗？
