order remains the same in rearranged list
i think this is a bug: trying to prepare an ordered table of values of a function and its derivatives, i found that the original order within the list of points i created remained unaltered although rearranging it afterwards by hand.
operating system: MS Windows XP
Java version: jre1.6.0_22 (i guess... it is the newest reference in the Java folder)
steps of how to reproduce the bug:
1. create several points.
2. use ALT+left click to select them and create a list in the input bar.
(press enter to confirm the list)
3. try to redefine the list, including new points or exchanging the order of the ones originally in it.
(the values in the list seem to be the ones in the first definition, not the latest!!)
observe that the formula in the spreadsheet x(Element[llista1, 3]) returns x-coordinate of the old 3rd point in the list, B, instead of the actual and expected value x(D).
maybe it is relevant that my points were created by sets: firstly, solutions of f(x)=0 (=> A, B, C); then Extremes[f] (=> D, E, F); finally Extremes[f'(x)].
weird: can't these points be used separatedly??
