Need help with connected / linked pop-up menus

-

want select preset.

what did create 2 pop-up menus. first preset folders , second presets folder.

each pop-up group has pop-up , static field current choise.

 

after selecting different value first pop-up menu want have second popup menu filled new, right presets of folder.

the first time works correct.

however when selecting different folder see "preset table"  filled correct new preset of folder. static field below second pop-up menu shows first value of correct new presets. second pop-up menu still contains presets of first folder , not new folder.

yet in observer see preset table contains right , new presets.

 

my code below.

i based on sample in sdk manual.

question: how can update second pop-up menu pop-up menu shows right presets.

 

code below

if popup items not fixed (and in case, it's not), can bind property.
