Hi, it matters that your assign and initialize functions have DownValues. Panel@DynamicModule[{x, y, assign, initialize}, Grid[{{"", "A", "B"}, {"w/ assign:", RadioButton[Dynamic[x, (x = #; assign[]) &], True], RadioButton[Dynamic[x, (x = #; assign[]) &], False]}, {"w/o assign:", RadioButton[Dynamic@x, True], RadioButton[Dynamic@x, False]}, {"value:", Dynamic@x}}, Dividers -> {False, {False, True, True, True, False}}, Alignment -> {Left, {Center}}], Initialization :> (assign[] := (y = x);(*further variables to update*) initialize[] := (x = True; assign[]);(*initialization function*) initialize[];)] Cheers Patrick On Tue, 2010-01-19 at 05:14 -0500, IstvÃ¡n wrote: > Dear Group, > > I have some problem with a complex interface inside a DynamicModule. > This is a toy version of the program, which can fully reproduce the > malfunction: > > Panel@DynamicModule[ > {x, y, assign, initialize}, > > Grid[{ > {"", "A", "B"}, > {"w/ assign:", RadioButton[Dynamic[x, (x = #; assign) &], True], > RadioButton[Dynamic[x, (x = #; assign) &], False]}, > {"w/o assign:", RadioButton[Dynamic@x, True], > RadioButton[Dynamic@x, False]}, > {"value:", Dynamic@x} > }, Dividers -> {False, {False, True, True, True, False}}, > Alignment -> {Left, {Center}}], > > Initialization :> ( > assign := (y = x);(* further variables to update *) > initialize := (x = True; assign); (* initialization function *) > initialize; > ) > ] > > Now for some reason, the radiobuttons do not function as intended (at > least as I want). > The following clicking orders do not work: > > [w/ + B] then [w/ + A] > [w/o + B] then [w/ + A] > > these work correctly: > > [w/ + B] then [w/o + A] > [w/o + B] then [w/o + A] > > I guess, that the problem is with the "initialize" (or the "assign") > function.
