fiogf49gjkf0d Rekha,
A couple of approaches you can take. Others may have some other approaches that will work, too.
First, you could use a #INCLUDE statment that outputs XML that contains all the potential values you need to populate picklist 2 when picklist 1 changes. In JavaScript clear picklist 2 and then use the XML to repopulate picklist with the appropriate values.
The second approach is a slight variation on the first. Use a #QUERY tag and the output=xml option to generate the potential values for picklist 2 and use JavaScript (as in the first idea) to populate picklist 2 when picklist 1 changes.
I've used both approaches with success. I like option 1 a little better as I can control the generated XML a little better.

fiogf49gjkf0d Hi,
Id be careful using the xml approach if the cascading picklist can have a lot of different values - we had a real depreciation in speed when a lot of new options were added (a few thousand). If you are working with lots of options (I mean in the hundreds at least) it might not be plausible to load the XML, or even use a javascript array generated using an included action. The way I got around the speed issue was to pop a modal dialog onchange of the combo and populate the next combo using this (autoclose the modal after populating the parent form). Make the modal size 0,0 and place it in a corner so the user doesnt notice unless they look too hard!!
That said if you have very fast servers the xml may work better for you than it did for me.
Thanks,
Nick |

fiogf49gjkf0d Probably the best approach is to use javascript and the xmlHTTP object to request the values for the necessary picklist when the value on Picklist 1 changed.
1) Build an Action to retreive the appropriate Values given a Picklist Name. This action would either return the raw list of values on XML or a string with the Options value.
2) From the OnChange event handler of Picklist one, call the Action passing the Picklist as a parameter. Depending on how you are returning the resultset on step 1, go ahead and apply the values to Picklist 2.
