Hi,

I'm often using ESdat Server (ESdat Online) to import laboratory reports with intent of them matching up to Sample Delivery Groups. This includes importing a zipped file containing lab report files header.xml, samples.csv and chemistry.csv.

However I've found the following error appearing sometimes (but not always):

"An asynchronous operation cannot be started at this time. Asychronous operations may only be started within an asynchronous handler or module or during certain events in the Page lifecycle. If this exception occured while executing a Page, ensure that the Page is marked <%@ Page Async="true"$>"

When this eror comes up the lab data will import, but the assignment of sample depth, locations and type (as assigned in PLog) doesn't occur. Any suggestions?

Thanks, James
