V2010 Report aborts with string to integer conversion error
SYMPTOMS
After a recent change in a report, it no longer executes properly when launched from Enterprise while it still works fine when launched in Report Designer. In Enterprise, the report is not displayed, instead there is an error message.
ERROR
Conversion from String "" to type Integer is not valid
REASON
It might be that the report has been edited and saved using IE11. IE11 is not supported in Changepoint V2010.
RESOLUTION
Open the report for editing in IE8 or IE9 and then re-save it.
