Seam Direct JavaScript Integration能否采用同步方式

我用过DWR,可以这样进行同步方式调用：

		
var modules;
SysFacade.getModules(Divo.getUserId(), {
			callback : function(retValue) {
				modules = retValue;
			},
			async : false
		});

能否在Seam Direct JavaScript Integration中进行类似的同步调用？

看来用JBoss Seam和它的Remoting功能的人好像不多.

经过2天的努力, 决定修改jboss-seam-remoting.jar中的
remote.js, 使其支持同步远程调用功能.

修改前:

 asyncReq.open("POST", Seam.Remoting.resourcePath + path, true);

修改后:

 asyncReq.open("POST", Seam.Remoting.resourcePath + path, Seam.Remoting.async);

用法举例:

	// 远程调用(兼容DWR和JBossSeam)
	function rmtCall(method, callback, params, isAsync) {
		var s = method.split('.');
		var callParams = [];
		if (params) {
			for (i = 0;i < params.length; i++) {
				callParams.push(params[i]);
			}
		}
		if (Seam.serverSide) {
			callParams.push(callback);
			var obj = Seam.Component.newInstance(s[0]);
			Seam.Remoting.async = isAsync;
			eval('obj.' + s[1] + '.apply(obj, callParams)');
		} else {
			callParams.push( {
				callback : callback,
				async : isAsync
			});
			eval(method + '.apply(' + s[0] + ', callParams)');
		}
	}
