Hello,
I have the next expression:
{(listadoHYG_cabecera.fechaFactura == null) ? listadoHYG_cabecera.fechaInicioFmto+" - "+listadoHYG_cabecera.fechaFinFmto: listadoHYG_cabecera.fechaFactura}
I need compare the field fechaFactura with null, but it doesn`t work. The field fechaFactura contains null. How should I use the comparison operator?
Thank you!

Hello.

What type of datasource do you use?
Usually, the null values are converted to empty string.

Thank you.

I use JSON datasource.
I compared it with an empty string and it works. Thank you.

Solution:
{(listadoHYG_cabecera.fechaFactura == "") ? listadoHYG_cabecera.fechaInicioFmto+" - "+listadoHYG_cabecera.fechaFinFmto: listadoHYG_cabecera.fechaFactura}
