selenium - Seleium/Ruby - NoSuchElement when trying to access an item in a modal popup -

what i'm attempting:

1. click on profile picture of user created: http://screencast.com/t/ajcfi3xa

2. click on , make selection drop down in pop modal: http://screencast.com/t/ahgohlg05

the selenium ide picks steps as:

1. click > id=patientphoto
2. selectwindow > name=modal3 (note modal number changes , increases exponentially, if run these steps again next time around it's modal4)
3. click > id=ext-gen115 click > //div[@id='ext-gen179']/div[2]

this playback in ide works without issue.

my code:

@driver.find_element(:id, "patientphoto").click wait_for { displayed?(:id, "ext-gen31") } @driver.find_element(:id, "ext-gen31").click @driver.find_element(:xpath, "//div[@id='ext-gen179']/div[2]").click 

in other places/workflows have switch default content switch frame trick:

@driver.switch_to.default_content @driver.switch_to.frame('chartframe')  

but no combination of working here.

other things i've tried:

1.  switch last window this:  @driver.switch_to.window(@driver.window_handles.last) # doesn't fail step after (finding drop down) fails 2.  @driver.switch_to.frame('modal4') attempt access items in modal  # fails think because modal number keeps changing  

here's page coding - http://screencast.com/t/osiigjxdblk

the selenium errors vary based on i'm attempting it's either timeout or cannot find element.

if there iframe dynamic id, try use following line of code switch it:

@driver.switch_to.frame(@driver.find_element(:xpath, "//iframe[contains(@id, 'modal')]"))
