Creating reports and dashboards | Stimulsoft community forum

Hi,

we upgraded, now some reports not load because of null Reference exception. If i change the font from "Arial Narrow" to "Arial" it is working fine. Arial Narrow is installed on the system.
* We also use the JS version there the "Arial Narrow" makes no problems
* The Designer is installed on that system where the report is generated with the dotnet version. The designer see the "Arial Narrow"
* The report is generated in a IIS backend

Hello,

Please send us a sample that reproduces the issue for analysis.

Thank you.

Ok, i found my problem. In GDI mode i have to register all fonts i want to use. Some was registered but not Arial black and narrow.
The old version seems to silently fall back to Arial if the font was not registered.

A helpful error message instead of "Null Reference exception" would be very nice. Something like "Font Arial Black must be registered in GDI Render mode. See StiFontCollection.AddFontBytes(...)"

Hello,

Thank you for the information.

We have added this task to our to-do list.

Thank you.
