ViewActivated Event

[Phillip_Miller]

HI.

I have this code that works perfectly when manually run through an external app or command. What is does is checks the parameters of an object and does some calculations on them and then writes revised Parameter values to that object if they require.

I want to automatically set this to check when a view is changed in revit using the View Actiavted event handler. I have it all set up using the exact same code but it spits out an error as in the atatched Pic.

Can anyone hepl me or suggest what I need to do?

Cheers

Phillip

I forgot to say that this is using Revit 2010 API. I have also tried wrapping the command in a transaction but I get the error message as attached.

Any ideas out there?

have you found a solution?
I am hoping to use an application level macro to do a similar task.

It seems transactions are temporarily disabled, the question is why. I would presume either another transaction is in progress, or Revit requires a moment after a view is activated before making model changes. You could try adding a small delay, or perhaps verifying the view is active before attempting the transaction? I'm not to familiar with the 2010 API, so not sure if this will help.

In the end I gave up and created a manual update command. It all changed in Revit 2011, and I have updaters doing it automatically. I haven't tried the view activated in 2011 but if it was still a problem you could subscribe to the new idling event and do your code in there.

Just some thoughts.
