ar pageData = this.comp("pageData");//页面的临时数据集
var designDocsData = this.comp("designDocsData");//页面的临时数据集
var tableMap = new biz.Request.MapParam();
        tableMap.put("pageData",pageData); //出错
        tableMap.put("designDocsData",designDocsData);

使用map来传递页面不同的数据集，但是出现错误：

数据集不算大，为什么会出现这种错误，难道不是post传参吗？请解释一下问题的原因。
这样的问题下面，如果我还是想要使用map 一次传递多个数据集的西悉尼转化为后台的Table对象，如何进行处理？

jishuang

tableMap.put("pageData",pageData.toJson());
这样看看
