Issue
Get "Type error: cannot call method "toFixed" of null" error message when opening a TGML graphic, upgraded to Vista 5.1.7
A TGML script has stopped working after upgrading to Vista 5.1.7
Environment
TAC Vista Workstation 5.1.7
TGML editor 5.1.7 219
Cause
Javascript method toFixed can only be used with numerical values. The TGML engine in TGML 5.1.7 is stricter than the older versions, so an upgraded script may have worked in previous versions.
Resolution
An example when using convertCustom element.
Original script:
function convert(value)
{
value = value.toFixed(2);
return value;
}
should be:
function convert(value)
{
value = Number(value).toFixed(2);
return value;
}
