Strange issue with setValue

[drahkar]

Could someone give me some thoughts on what the following would throw a C stack overflow error?



function onValueChanged()
local spectype = getValue();
setValue(spectype);
end

setValue() fires an onValueChanged event, which then calls setValue(), which then fires an onValueChanged event, which then calls setValue(), ... the loop continues until the FG engine falls over.

.... Good point.

I had this problem when I originally created fields to synchronize with each other from different records.

You have to add in a local flag to avoid the cycle.

Based on your example:


local locked = false;
function onValueChanged()
if not locked then
locked = true;
local spectype = getValue();
setValue(spectype);
end
end
