Defaulting a Query Combo Box to a Non-Null Selection

[Ryan Herbeck]

I have a query list form with a set of text fields and combo boxes for search criteria. I am looking to default a query combo box to a non-null selection when a user first views the query list or when the search criteria is cleared. Is there an existing configuration function that would allow the setup of this default behavior?

Hi Ryan,

From my experience there is no specific function/property to default the value for the combo.

However you can achieve it by doing below:

• For the initial load of the form/screen
  • In the script tab, create PostMessage function (which gets executed after the UI is rendered)
  • In the postMessage find your combo box and set the value
    • Using findViewpath , “value” is what you want to set
• Above can be wrapped in a function which then can be called from a data action/ui action when “clearing” the search criteria.

Hope that helps.

Regards,
Dhruv

The defaulting of combo is mostly achieved by setting the initializer of the attribute it’s bound to, but this only works in Add/Edit scenarios not search/query forms.

Below is how you would set the default selection on a combobox

(define defaultValue “test”) <– Not this will most probably be the enum object

(define comboModel ((this’findView ‘(filterCombo))’collectionModel))
(comboModel’currentIndex (comboModel’find defaultValue))
