Hi, Jesus,

I have a similar requirement, but how do you distingluish between
the "accept" action and the "refresh 2nd pupup" action on submit.
since you trigger the accept on the 1st popups change
I put the first pop-up in its own form. When it returns, I know the
value selected there, persist it in the WOComponent and don't need to
see it again on the second submit.
Regards,
Jerry

Hi, Siegfried,
I did something similar in an application a while back.
Translating the problem domain for that application to your two
button names: I created my page with the Location pop-up's list
attribute bound to the initialized array of locations. I bound the
Building pop-up's list attribute to an empty array. I also added
the onChange attribute to the Location button:
onChange = "javascript:this.form.target='_parent';
this.form.submit()"
The action method for the form submission used the Location's
selection attribute value in an EOQualifier which I used to fetch
the values for the Building's array for that location. The action
method, of course, returned context().page() to display the same
page again, but with the Building's pop up filled in.
By adding the "onChange" attribute to the Location's pop-up, you
save the user having to click a button after selecting the
location. The page still has to refresh, but it feels a bit more
convenient having the page refresh automatically upon selecting a
Location.
For a smoother approach without page refresh, you would have to
move to Ajax or download the complete Buildings array initially to
some JavaScript variable and play some games with JavaScript to
filter the ones you want based on the Location selection.
Regards,
Jerry

Hello,
I have two dynamic elements (WOPopUpButton) named Locations and
Buildings. Now I would like to set the list binding in the
Buildings array based on the selection in Locations. Probably an
easy one, but as a sporadic WO user I have no clue yet.
Thanks,
Siegfried
