[CLOSED] Reverse Chaining in 8202?
Has Reverse Chaining been enhanced to the point that is doable out-of-the-box or using the GUI in 8202? Or do we still need to uses JavaScript or jQuery to make that happen?

How about bi-directional or selective chaining based on the result of a dual radio button? Something like:

* The Radio button has a selection for Country or Car.

* The first drop down list will display Countries if Country is selected.
  * The second drop down list will display cars if Country is selected.

* The first drop down list will display Cars if Car is selected.
  * The second drop down list will display Country if Car is selected.

Thanks In Advance, Doug

I though you could already do this in 8.1.04 with Conditions/Population in App Studio

This is another perfect reason/use case for why the new WF Designer they are building will need manual filtering creation and chaining capabilities beyond just the default automatic based on unresolved parameters they have in place now. Adoption will be far higher if they address this before claiming 1.0.

I thought with the Designer, if the parameters are in a dimensional hierarchy, they'll automatically get chained.

Possibly, but manual chaining is needed for non-structured data sets (for sites that don't have the time or resources available to structure the data properly for every single scenario across thousands of reports and applications), use-cases where you'd want a hidden control passing a hidden value, a chaining scenario that is more than a straight-forward hierarchy or even needing to be tied to such, scenarios where you want to force a certain control type for a specific control not available via the tool or when the tool thinks only certain control types are compatible, etc.

BabakNYC,

You can add chaining when you pull in a fex that has -DEFAULT parameters and assign controls to them. Or just assign controls to them then got to the parameters page, in the HTML Composer, and chaining 1 to 1 or 1 to several or several to one if you have a fex that'll handle all of them. The CAR file is a wonderful example that can be used for chaining. Country to Car, Car to Model. where Country, Car, and Model all have their own drop down lists and are fed from a single fex or the synonym.

But, Reverse Chaining is another beast all together... Normally done with JavaScript or jQuery. Not something I want to create and leave for others to maintain.
