bug in name, object(name), list
Hello, I have created a worksheet that traces a funicular line through any given set of arbitrary forces. It is a little like tracing a sort of "discrete" differential equation from a set of vectors positioned in the vector fields...
The mechanism works, it still needs some minor refinements but it works. The file attached can be used.
But there is a problem with the mechanism of collecting the input points in a list:
Whenever I save the file after erasing the first vector, it doesn't open again.
This happens quite often, so I made the "init" button to rebuild the missing objects. (missing lists)
But in this case it doesn't work.
Even when I execute manually the first line:
alltexts=RemoveUndefined(Sequence(If(IsDefined(Object("text" + (n))), Object("text" + (n))), n, 1, 500))
it still doesn't work!
It looks like it is a bug in geogebra.
Any help would be welcome!
