index not scalar at __dlg:radios, line 5

Some time before I already asked about this error: "Nasal runtime error: container index not scalar
at __dlg:radios, line 5"
But no solution was givven.
Maby it is related to the airplane you fly on, but with the Ctation-II it is there.
It is caused by a prop not set at start : '/instrumentation/transponder/inputs/knob-mode'
Solution :
Add this code in the radios.xml at : fgdata/gui/dialogs/
after :

Code: Select all

var modes = ['OFF', 'STANDBY', 'TEST', 'GROUND', 'ON', 'ALTITUDE'];
           var v = getprop('/instrumentation/transponder/inputs/knob-mode');

enter:

Code: Select all

if( v == nil){
            setprop('/instrumentation/transponder/inputs/knob-mode',0);
            v=0;
        }

Then the error is gone and even no warning is displayed.

the code should be fixed to use value-defaulting: http://wiki.flightgear.org/Nasal_Conditionals

Also note that you can simply tell getprop() to assign a default value through its 2nd argument

Hello Hooray,

I know, but this was not my code... Only to let "someone" know.
Because I see this message already for such a long time ....
