Using UpdateFormulaContext in Lotus Notes
The new formula is @UpdateFormulaContext in Lotus Notes, and all it does, in lay terms, is switch where the code is running. For example, if you compose a document, normally the code would continue to run where you were before the document was composed. But using the new @-function tells the Lotus Notes 6 client that the code should now run in the composed document.
So, here’s some code that can be placed in an action button. It will forward the document and set the subject on the forwarded message.
@Command([MailForward]);
@UpdateFormulaContext;
@SetField(“Subject”; “This is the subject”)
Since the formula was introduced in Lotus Notes 6, if you have a mixed environment of Notes 5 and Notes 6 clients, you can prevent any errors in the Notes 5 client by forwarding the message and then exiting if the user has Notes 5. The subject won’t be set, but the user won’t get an error message, either. That could be accomplished by code similar to this:
@Command([MailForward]);
@If(@TextToNumber(@Version) < 184; @Return(“”); 0);
@UpdateFormulaContext;
@SetField(“Subject”; “This is the subject”)
The check for the version being less than 184 will stop the rest of the code from running if the user has Notes 5. So the message will be forwarded, but the code will stop there.
