Popup form issue

[karinep]

Hello everyone,

I was reading this thread Related data popup form - custom form JS and this person had almost the same issue as I am. I have a button in my form that open a list to add a new data in that list and I have a new element render there that calls a js to build a tree. How can I include this tree js file to build the tree in the popup? I was taking a look in databasejoin-min.js and there is a function called start that do some things in this popup, is it possible to include this file just when this popup is built?

Thanks.
