如题 target is null for setProperty(null, "name",严重: Could not create and/or set value back on to object
Method "setProductType" failed for object net.epsshop.action.admin.ProductTypeAction@163bad4 - Class: ognl.OgnlRuntime
File: OgnlRuntime.java
Method: callAppropriateMethod
Line: 1265 - ognl/OgnlRuntime.java:1265:-1
ognl.MethodFailedException: Method "setProductType" failed for object net.epsshop.action.admin.ProductTypeAction@163bad4
警告: Error setting expression 'productType.name' with value '
get和set方法都有
这个破问题困扰我一天，以前遇到过，又忘了。。。（哎，人老了记性不太好了）
解决：
将
private ProductType productType ;
改成
private ProductType productType = new ProductType(); //初始化（其实我到现在都郁闷，以前都是没有初始化怎么都没出错，有高手路过的，知道原因的请告诉在下，谢谢了！）
