Thanks for helping!
this gives me a glimpse of how I should handle that.
On the "On Select" propriety of the copy button, I add a boolean variable to manage the copy activity.
Set(Copy,true);
ResetForm(Form_frmCtrl);NewForm(Form_frmCtrl);Set(varFormVisible, true);
and on the combo box "DefaultSelectedItems" property I set it like this:
If(Copy,
//true
If(!IsBlank(DataTable_frmCtrl.Selected),
First(Filter(Office365Users.SearchUserV2({searchTerm:DataTable_frmCtrl.Selected.Email_Solicitante}).value, Country="Brazil", "MyDomain.com" in Mail))
)
//false
)
and to do the same with any other form field, I have to put a condition to check if the Copy value is "true", as an example for another text field on the form:
If(Copy,
//true
If(!IsBlank(DataTable_frmCtrl.Selected),DataTable_frmCtrl.Selected.Ticket_ESS),
//false
""
)
