In my Tempo tasks (7.4) I am trying to use cascading dropdowns with rules.
I tried with this code (inputs:type and failure) but it doesn't work (my rule - getFailureDescription works).

= load(
local!type,
local!failure,
a!formLayout(
firstColumnContents: {
a!dropdownField(
label: "Type",
labelPosition: "ADJACENT",
required: true,
choiceLabels: {
"Tread",
"Wire"
},
choiceValues: {
"Tread",
"Wire"
},
value: ri!type,
saveInto: local!type
),
a!dropdownField(
label: "Failure",
labelPosition: "ADJACENT",
required: true,
choiceLabels: {
rule!getFailureDescription(
local!type
)
},
choiceValues: {
rule!getFailureDescription(
local!type
)
},
value: ri!failure,
saveInto: local!failure
)
...

I think an if statement is still a good way to go.

1)Initialize local!type:"" as a null text.
2)Put an if statement around the second dropdown
if(isnull(local!type),{}, a!dropdown etc...)

This way the second dropdown only appears and executes the query rule when a choice has been made for local!type
