Dear all,
I used sakai app builder to generate a full CRUD application for sakai 2.5.4
. It can run in sakai with no error.
In ExternalLogic class and ExternalLogicImpl class , i add a function. In
this function, I used some APIs of SiteService, but it has some error when
run in Sakai :(.
Now, I test again, by copy a function ,change it's name ( and change it's
name in ExternalLogic ) and use it, but it has error when I run it in Sakai
portal>"<.
I don't understand, with same function, original function can run, but copy
function can't run :(.
I feel it's very hard to use sakai service for my application :(.
Please help me !!!!
