Test on null value

[fabien]

Hi,

we enable or disable panel with a condition on a null value.

Files attached :
- liste.mrt : report.
- data.json : data used to produce report.
- Line_type_1.png : expression to filter type 1.
- Line_type_2.png : expression to filter type 2.
- export.png : incorrect pdf export

lines with order 1, 3 and 4 should have "CASSOULET CREOLE AU COCO", "BOITE TRANSLUCIDE PP 37,5CL /500" and "ARABIS caucasica" captions. This the expression in Line_type_1.png who contains artgrilleval_lib1 == null
lines whith order 5 should have "ENSEIGNE DE TROTTOIR DIBOND SUR PIED RES" caption. This the expression in Line_type_2.png who contains artgrilleval_lib1 != null

I think expression are incorrect but i don't understand where is my error.
I've unchecked "Convert nulls" on report component.

Thanks,

Fabien

Hello,

Your column is a string, please check the following expressions:
{lignepiece.lignepiece_lib == ""}

Thank you.

Hi,

It works.
it is important to know that the test should be done with double quotes and not single quotes.

Thanks,

Fabien.
