Setting Visibility at Runtime [message #47962]

Hi Everyone,
I am trying to set a table invisible (if the corresponding query returns
no record), and display "No Records Found !" instead.

I tried using the 'visibility' option but I could not figure out how to
insert a tag in the design file at RUNTIME at the appropriate location
which would set the table invisible.

Any help would be greatly appreciated.
Thanks a lot

Rahul

I too would be interesting in information on how this might be
accomplished (though I haven't really looked into it at all) :D

Hi,

This use case has been thought of while designing the Table/List report item,.
one way of doing it would be

- Add a label element to the table header or footer, with text = "No records
found"
- Define the visibility rule on the lablel, hide in all views , with
expression= Total.count > 0

Let me know if this works.

I tried this for the visibility of the table, but the Total.count seems
not to be recognized.

Juergen,
-- One minor correction above, the right expression syntax is Total.count() > 0,
-- Visibility of the table should work
-- Return type of Total.count() is numeric, looks like there is a bug, if the number
of records are 0, Total.count() returns null. I will log a bug in bugzilla.

Thanks a lot, this works!

How did you know the Total.count()? I could not find it in the list of
available object in the report designer.

This works for Table/List but can we do something similar to Chart?

I keep getting this error message when there is no data:
There are errors on the report page:
Error1:Failed to render Chart
The dataset used by the Chart is invalid

Thanks,
-l.t.
