Cascading combo boxes in form

Hi i am trying to create list and detail pages in my app similar to the one created in the OSMDB app in the web development training. the issue that i am running into is i have cascading combo boxes in the detail page and when i select a record and navigate to the detail page the cascading combo boxes are empty.  is there a different method of creating cascading combo boxes that would allow for the combo boxes to be populated the way they where saved when i recall the record?

I used this example to base my cascading combo boxes off of - https://www.outsystems.com/forge/697/

Hi Jay.

They can keep the value between screens if you use Session Variables in the combo boxes and don't clean them in preparation.

The thing is, in Details you are showing data from the Record. If you copy data from one screen to the other, you are corrupting data.

Hi Jay Brooks,

you can debug your preparation  and you can find why value are not populating in your detail screen.

For your  help i am attached simple example of cascading like your forge. 

Sample screen : Check


Hope this help

Regards,

Rahul
