You can sort nested cdt just by using todatasubset function.

Try putting an @OrderBy("sortfield") annotation on your XSD where you include the nested multiple. This will mean it's always sorted that way, but that could be sufficient for your needs

As There are multiple values in each row, Appian doesn't know which one to consider for sorting.
As far as I understood from what you said. Your data should look like this:
ID....contact
1....a,b,c,d,e
2....b,f,,h,j

so now, if you want to sort by lastnames(a,b,c,d,e..) Appian is not sure which one to consider. When the 'a' from id 1 is considered with 'b' from id 2 the sorting will not be same as when 'd' from id1 is considered with 'b' from id2.
Sorting can be done on columns which have only one element per cell.
Hope this helps.

How do you want sorting on a multiple field to work? What should it sort by?

when i click on the sorting column it throws an error [contact.LastName] because it is a complex,multiple or child of a multiple data type.

So do you want to display sorted multiple last names in a single row?

RE: Sorting a paging grid column that is a nested CDT.

rohann179 — Mon, 23 Jul 2018 19:49:49 GMT

it looks something like
Id-Int
Sponsid-Int
anumber-Int
Contact-Type(Contact)-Multiple

The Sorting should happen on the Last name in the contact CDT

Multiple

Try using the index and then dot notation if that child field is an array or else parent.child should work. I can address your issue more precisely if you can provide the exact CDT.

Create a dictionary from your nested CDT. Each column in the table is represented by an element in the dictionary.

I would create a rule that takes in your nested CDT and then in the rule you have something like the following which returns back a dictionary:

= {

a: ri!myCdt.a,

ab: index(ri!myCdt.a, "b", {})

}

Then in your table you just reference the dictionary.

Is the child CDT a single or a multiple?

RE: Sorting a paging grid column that is a nested CDT.

dot notation can help.

hi xingc,
is your nested cdt is single or array ?
if single,fetch your details by query rule,and convert id in todatasubset with sorting filed of your childfield ,see below example

todatasubset(
rule!XYZ_empDetails(),
a!pagingInfo(
1,
- 1,
a!sortInfo(
field: "parentfield.childfield",
ascending: false()
)
)
).data

if you nested cdt is array better to create data base view.
