@toxonic I changed the following lines....
// Sets the array as Control Value and repaints the panel
inline function _updateInternal(p)
{
p.setValue(p.data.buttonValues);
p.repaint();
p.changed();
}
to...
// Sets the array as Control Value and repaints the panel
inline function _updateInternal(p)
{
local pGet = p.getValue();
for (i=0;i<p.data.buttonValues.length;i++) pGet[i] = p.data.buttonValues[i];
p.setValue(pGet);
p.repaint();
p.changed();
}
I loaded the value of the panel into a local array, write the changes of the button data array to the local array and save the panel value again with p.setValue()
This works to me, when i set the maximum amount of steps (64) at compile time.
Nevertheless, thank you much for your effort! :-)
