Action OnConfigItemUpdate - how is this supposed to work?

[shill]

I have a dropdown in my action configpage with 2 choices - "All Devices" and "Specific Device", and I built it with OptionKeys using values of "1" and "2" respectively.

When this event fires and the configChangeView is examined, there are no OptionKeys, and the Options are just "0" and "1". And if I use "GetSelectedOptionKey", it comes back blank, but "GetSelectedOption" returns "1", even though I've selected "Sepcific Device" (2).

Anybody have experience with this? The documentation is practically non-existent on what these functions do or how to use them...

I had no difficulty with the update logic. I found the Sample plugin to be sufficient for me to understand how to migrate. I also did a post in this forum that contained a step by step of migrating action (and triggers) from HS3 to HS4.

I've run into two defects that are preventing both normal functionality and migration, so I beg to differ!

And yes, I've seen (and studied that) so thanks!

I am not totally following the terminology on your original post. I assume that event fires means a call is made to OnRunAction of the class where there action is defined. configChangeView and OptionKeys is not something I am familiar. To get the action parameters that the user setup I use the class's Id's. Once I get the view's/control's values I then just use the logic I ported from HS3 code. In my example I have a select list and a text box that user configures in the event action setup.

   Public Overrides Function OnRunAction() As Boolean
        Dim iActionType As Integer = If((TryCast(ConfigPage?.GetViewById(ActionTypeSelectListId), SelectListView))?.Selection, 1)
        Dim sInput As String = If((TryCast(ConfigPage?.GetViewById(ActionInputId), InputView))?.Value, "")
        Return plugin.HandleActionX(iActionType, sInput)
    End Function

    Private ReadOnly Property ActionTypeSelectListId As String
        Get
            Return $"{PageId}-ActionType"
        End Get
    End Property

I also show a select list and a toggle at

In this case it is executed following the "Save" button on the HS4 replacement for HS3 ConfigDevice, but getting the view's values processing is the same as if it was a result of a event action OnRunAction.

I dont remember if I posted the OnConfigItemUpdate code in my step-by-step for action. It is

Protected Overrides Function OnConfigItemUpdate(ByVal configViewChange As AbstractView) As Boolean
        Dim selectList As SelectListView = TryCast(ConfigPage.GetViewById(ActionTypeSelectListId), SelectListView)
        Dim iActionType As Integer = selectList.Selection
        Dim inputView As InputView = TryCast(ConfigPage.GetViewById(ActionInputId), InputView)
        Dim sMessage As String = configViewChange.GetStringValue 'inputView.GetStringValue

        Dim changedActionType As SelectListView = TryCast(configViewChange, SelectListView)
        If changedActionType IsNot Nothing Then
            'change made to the selector?
            If selectList.Selection <> changedActionType.Selection AndAlso selectList.Selection <> -1 Then
                ConfigPage = InitNewConfigPage(changedActionType.Selection).Page
                Return False
            End If
        End If
        With New System.Text.StringBuilder
            If iActionType = 0 Then
                'send mqtt message
                Dim i As Integer = InStr(sMessage, "=")
                If i = 0 Then
                    ConfigPage = InitConfigPageWithFeedback("No action will be performed because message not entered as Topic=Payload").Page
                    Return False
                End If
            ElseIf iActionType = 1 Then
                'publist
                If Not System.IO.File.Exists(gDataPath & sMessage & ".pub") Then
                    ConfigPage = InitConfigPageWithFeedback("Publist publication list " * sMessage & " will not execute as an event action until " & sMessage & " is created.").Page
                    Return True
                Else
                End If
            End If
        End With

        Return True

    End Function

Sorry, I meant when that method (OnConfigItemUpdate) is executed. But I think the issue I originally posted about (not having insight about what was selected) was corrected in the latest PluginSDK, since I haven't had that problem since I udpated.

There's still no way to do a multi-select dropdown, though, and text entered into an InputView get lost if you change a dropdown (and presumably other types that do a postback like toggles). And RemoveViewByID also doesn't work, so dynamically changing the configpage can only be done by a hack of a workaround to forcibly recreate the whole ConfigPage.
