Hi,

Has anyone is having experience on Salesforce integration with PayPal Using PayFlowPro gate way?

I want to do integration using HTTPS request.

I am new to Integartion. Can anyone plz suggest any link or source code?

Regards,

Nilesh.

I recently tried to package an app with custom settings. Unfortunately I couldn't write test methods because I wanted to create custom settings instances to test the various areas of my code. The error message I got is well known to me: MIXED_DML_OPERATION, DML operation on setup object is not permitted after you have updated a non-setup object (or vice versa).

Since inserting a Custom Settings object is a setup operation I can not create a custom settings and then proceed to create my test data. I tried creating my custom settings inside an @future method and this didn't work either (I did wrap my @future call with Test.startTest() and Test.stopTest() to ensure my @future method completed (i.e. to force synchornous execution). But I still got the same error message.

Ultimately what I did was write my code in such a way that the Class which relied on the custom settings had a local variable for the custom settings which I could set. In normal operation my code will query the custom settings using .getInstance() however my testMethods will all override this normal behavior and "force" set the custom settings.

My class which uses custom settings is below as is my class which tests my code. I hope you find this useful, and if you spot anything wrong with this please let me know. Thanks,

Caleb
