有时候需要在backingBean中调用某一taskflow, 可以使用以下代码调用。不过只适用于可单独运行的taskflow，含有page fragments的taskflow不在此范围。

代码如下：
{% codeblock lang:java %} public String callTaskFlow() { FacesContext fctx = FacesContext.getCurrentInstance(); ControllerContext cc = ControllerContext.getInstance(); String taskflowId = "btf_task"; String taskflowDocument = "/WEB-INF/btf_task.xml"; Map params = new HashMap(); TaskFlowId tid = new TaskFlowId(taskflowDocument, taskflowId); String taskflowURL = cc.getTaskFlowURL(false, tid, params); ExtendedRenderKitService erks = Service.getRenderKitService(fctx, ExtendedRenderKitService.class); StringBuilder sb = new StringBuilder(); sb.append("window.open(\"" + taskflowURL + "\"").append(",\"_self\");"); erks.addScript(FacesContext.getCurrentInstance(), sb.toString()); return null; }
