Hello All,

I am getting some strange error in Custom Module Implementation.

I have Create one Custom Module Named "Test" sucess fully

Define class of Test Module TestUser.

Define UI interface like AddtestUser and EditTest User.

Now I am able to add testuser and edittest user successfully.

Now I am going to fetch adobe user and add into table success fully.

Now I am going to fetch Courses of adobe and getting error.. my error is i am getting 100 record from adobe connect and i am using foreach and that loop run 100 times and when i am seeing in db table i am getting only 1 record!!!!!!!!!!!!!!. Yes only one record!!!!!!!!!!!!!!!!!!!!Strange but i think kentico Merge function which is used by kentico developer in api is not proper or i am doing some mistake ...btw .. i am adding 100 course and in db only one course is there.....
