I was trying to use the hierarchical band band but i am getting an error

Method: [GetItems]
Object reference not set to an instance of an object

i have one header band, and Hierarchical band. in Hierarchial band i have set the "Key Data Column", "Master Key Data Column", when i do the preview, i am getting this error.

If you have any small example for this it would be much helpful.

Please see the report template in attachment. You can open it in the Demo.exe sample application.

Thank you.

I was facing the same problem

Method: [GetItems]
Object reference not set to an instance of an object

and found the issue, that the column name i have given for "Key Data Column" Has the null values. so it is throwing that error. Is it Possible to fix this ?

Thank you for your detailed information.

We will inform you in this topic when the fix will be available.

Thank you.

Hello,

Problem fixed. Patch will be available in build from 9 Oct.

Thank you.

Hello,

Thanks for the fix. Now the NULL issues got solved, but having some issues with rows at same level.

Eg: I am having 2 columns
Key Data Column: pkCallListPosition
Master Key data Column: fkParent

The problem comes when there are 2 rows at same level. I mean there are 2 employees at same level under them there are 5 employees reporting to them. We wanted these 2 should be printed contineousely and then the rest 5 (who are all reporting to the above level) to be printed. But currently, it prints the First value, and under that it prints that 5 persons reporting to them then it prints the second one but that too is not printed at the same level.

Hope following will explain the problem better.

"EmpA" & "EmpB" are in Same Level, "E1", "E2", "E3", "E4" and "E5" are reporting to "EmpA" or "EmpB". All of them are reporting to "EMP"

The Result we wanted is.
---->EMP
-------->EmpA
-------->EmpB
------------>E1
------------>E2
------------>E3
------------>E4
------------>E5

But Currently it comes like....
---->EMP
-------->EmpA
------------>E1
------------>E2
------------>E3
------------>E4
------------>E5
---->EmpB


Thanks for your support.

Thank you.

Hi,

Thanks for the reply. But Now with the latest build i took (Stimulsoft Reports.Net 2007.10.19 D2005), i am getting the old error.

Method: [GetItems]
Object reference not set to an instance of an object

my report is not running.

I used to get this error when my "Key Data Column" has the null values. So this time i have filtered the null rows as well, but still no luck.

Thanks.

The problem is in the System.Nullable type. Your report have two variables with this type: var_Indent, var_Count. If you change this type then the report will work.

We will try to fix this issue, as soon as possible.

Thank you.
