Extend Features in Adobe Reader

hello,

 

i'm working on form has several dropdown lists fields wrapped individually hidden subforms become available (visible) once assigned check boxes selected. after testing form, works fine. however, issue i'm running coming after extend features in adobe reader. issue has dropdown items, in i'm using loop display list of items very in same way "purchase order" form comes adobe livecycle. problem before extending features in adobe reader, dropdown list shows items populated in loop planned, however, once extend feature in reader, list items appear twice i.e. item1, item2, item3, then, item1, item2, item3 again if "shadows" items.

 

when noticed issued in form, thought had done wrong, after double checking confirmed issued occurred on extended file , not on original file. so, decided test on "purchase order" form "extending features in adobe reader" , and same thing occurred "part no." items. can check out yourselves!!

 

i'd appreciate can give me solve issue.

 

thank you!!

 

hi,

 

if here see events "appear" fire twice when form enabled: event fired twice

 

i suspect have script in event docready or initialize.

 

you move script preopen event of dropdown. fires user opening dropdown.

 

another possible solution include following line @ top of populating script dropdown:

 

this.clearitems(); 

 

this clear list when event fires second time in reader enabled form , populate again once.

 

good luck,

 

niall
