SAP MI - MAM 3.0 - Context problem

[Former Member]

Hi All,

I am working on MAM3.0 application using MI 7.0.

Requirement: To add a check box to the Operation List screen, so that user can check the operation completed and keep track of the completed operations.

I have added a check box to Operation List and a evenHandler in the Controller. When i try to retrieve the OperationList in the event handler from the Context, i am getting Listdata as NULL.

Error:

An error has occurred

Component order

View com.sap.mbs.mam.order.control.OperationList

Event onShowOperationDetail

Error Code E503

OperationList.onShowOperationDetail(OperationList.java:152) - this the line where i am getting the List from the Context.

I could not find the where the problem is!! Any one worked on this application, please guide to solve the issue.

Thanks
