Hi,
I have a computed column called minutes. When I run the "preview results"
it all works perfectly. However, when I run the full preview of the
report, all of a sudden I get an error saying: The data type of computed
column "minutes" is java.lang.Integer, but one of its value is "null",
which cannot be converted to java.lang.Integer.
Anyone know how I can fix this?

currentIsStart = true;
}
MinutesStopped = DateTimeSpan.seconds(params["StopTime"],
params["StartTime"]);
params["StartTime"] = "01/01/2006 00:00:00 AM";
MinutesStopped
And this is the code used to display it in the report:
<VALUE-OF>if (row["Minutes"] > 60) {
hours = Math.floor(row["Minutes"] / 60);
mins = row["Minutes"] % 60;
result = hours + " minutes " + mins + " seconds";
} else {
result = row["Minutes"] + " seconds";
}
result</VALUE-OF>
(Yeah, I know it looks funny, but it was originaly hours and minutes, and
then got changed to mins and seconds and I haven't gone through and
changed the variable names. :))

You can do a check before you use the row values like
if ( row["details"] ){
if (row["details"].equalsIgnoreCase("STOP")) {
....
}
This should remove the nulls.

Can you try
if (row["details"] ){
Also I would imagine the error is in something like
row["reporttime"];
So you may want to check it as well.

Remember that an expression returns a value and it is always the last
statement you run, so
make sure the last statement has a value. It looks like you are using
MinutesStopped. Can you initialize that to 1?
Can you post your report?

So I looked at it some more, and fiddled around and it still doesn't work.
I changed the expression I was using as I came up with a way better one
(easier to follow and actually works more in the way the last one was
intended to work).
Here it is:
MinutesStopped = -1;
if (row["details"] && row["reporttime"]) {
if (params["LastWasStop"] && row["details"].equalsIgnoreCase("START")) {
MinutesStopped = DateTimeSpan.seconds(params["StopTime"],
row["reporttime"]);
params["LastWasStop"] = false;
} else if (row["details"].equalsIgnoreCase("START")) {
params["LastWasStop"] = false;
} else {
params["LastWasStop"] = true;
params["StopTime"] = row["reporttime"];
}
}
MinutesStopped
I can't post the report, but I could email it to you if you could tell me
your email address.
