Hi,

This exception has popped up today and appears to be happening when several of my colleagues are doing attempting to perform the same operation on the same page at the same time.

The error information is provided below.

The line of code at line 306 is:  pdf.Export(diagram, fullfilename);

We are hoping to launch this newly updated application this weekend, so this is a rather serious issue.

Thanks in advance for any advice.

Jim

Hi,

It's past our developers working time here and I'm afraid we can't help you much for your weekend launch. Our developer will investigate this next week. For the time being I suppose you could queue the export operations when for the same diagram and poll from the client to transfer the PDF when it's ready. Or simply lock on some shared object for the clients to wait each other's exports if the diagrams are small. (I have just seen your post above - try locking on typeof(Diagram))
