[Event Requests] OnInit in Pages "Prices Overview", "Price Worksheet", "Purchase Job Price Lists", "Purchase Price Lists", "Sales Job Price Lists", "Sales Price Lists"

[sschuh]

Why do you need this change?

Hi,

the reason why i need this is, i want to skip the opening of the standard pages and want to open my own individual pages.

Subscribed to the events in the above named pages, i am able to do the following:

example:

    [EventSubscriber(ObjectType::Page, Page::"Price Worksheet", OnBeforeInitPage, '', false, false)]
    local procedure PriceWorksheet_OnBeforeInitPage()
    var
        MyPage: Page "MyPage";
    begin
        if MyPricingIsEnabled then begin
           MyPage.Run();
           Error('');
        end;
    end;

Describe the request

Please add the events "OnBeforeInitPage" in the following pages:

"Prices Overview"
"Price Worksheet"
"Purchase Job Price Lists"
"Purchase Price Lists"
"Sales Job Price Lists"
"Sales Price Lists"

    [IntegrationEvent(false, false)]
    local procedure OnBeforeInitPage()
    begin
    end;

    trigger OnInit()
    begin
        OnBeforeInitPage();
    end;

Hi @sschuh,

Thank you for your extensibility request. To help us process it efficiently, please update the issue to include the required information.

📚 Extensibility Guidelines

Missing Information:

• Existing events or alternatives evaluated: Describe which existing events or other extensibility patterns you evaluated and why they do not work for this scenario.
• Performance note: Briefly explain how often this would run and the expected performance impact.
• Data sensitivity/security statement: Confirm whether any sensitive data is involved.
• Multi-extension interaction: Briefly describe any potential subscriber conflicts or multi-extension interaction considerations.

Please update the issue with the missing details. We'll automatically re-analyze once updated.

Additional Information

1. Existing events or alternatives evaluated

I evaluated the existing extensibility options on the affected pages, including:

• Page triggers such as OnOpenPage, OnAfterGetRecord, and OnAfterGetCurrRecord
• Available integration events already exposed on these pages
• Page extensions to modify layout or behavior

None of these options allow preventing the standard page from initializing before it is opened.
The key requirement is to fully replace the standard page with a custom page, which requires intercepting execution before the page lifecycle starts.

Events like OnOpenPage occur too late because:

• The page is already being opened/rendered
• The standard UI briefly initializes, causing flicker or side effects
• There is no clean way to cancel the page execution

Therefore, an OnBeforeInitPage event is required to:

• Redirect to a custom page (MyPage.Run())
• Abort standard processing cleanly via Error('')

---

2. Performance note

The event would execute only when the affected pages are opened:

• "Prices Overview"
• "Price Worksheet"
• "Purchase Job Price Lists"
• "Purchase Price Lists"
• "Sales Job Price Lists"
• "Sales Price Lists"

This is:

• User-triggered, not part of background or batch processing
• Executed once per page opening

The performance impact is therefore negligible, as:

• The logic is lightweight (simple condition + optional page redirect)
• No database-heavy operations are involved
• It does not run in loops or high-frequency contexts

---

3. Data sensitivity / security statement

• This request does not involve handling sensitive or personal data
• The event is purely related to UI redirection and extensibility
• All data access remains within standard Business Central permission and security boundaries

---

4. Multi-extension interaction considerations

There is a potential for conflicts if multiple extensions subscribe to the same OnBeforeInitPage event and attempt to redirect execution.

However:

• This is consistent with existing extensibility patterns in Business Central
• Conflicts can be handled by implementers using:
  • Feature flags (e.g., MyPricingIsEnabled)
  • Prioritization logic
  • Controlled subscription (single active extension scenario)

Additionally:

• The use of Error('') ensures a clear and deterministic exit
• Extensions opting into this behavior are expected to manage coexistence explicitly

---

Summary

The requested OnBeforeInitPage event is essential to:

• Enable clean page replacement scenarios
• Avoid UI flicker and late interception
• Align with existing extensibility patterns used elsewhere in the application

Implementation:

Add an OnBeforeInitPage integration event and call it from OnInit() in pages Prices Overview, Price Worksheet, Purchase Job Price Lists, Purchase Price Lists, Sales Job Price Lists, and Sales Price Lists.

Location in each page OnInit() trigger:

// PricesOverview.Page.al
trigger OnInit()
var
    FeaturePriceCalculation: Codeunit "Feature - Price Calculation";
begin
    OnBeforeInitPage();
    FeaturePriceCalculation.FailIfFeatureDisabled();
end;

// PriceWorksheet.Page.al
trigger OnInit()
var
    FeaturePriceCalculation: Codeunit "Feature - Price Calculation";
begin
    OnBeforeInitPage();
    FeaturePriceCalculation.FailIfFeatureDisabled();
end;

// PurchaseJobPriceLists.Page.al
trigger OnInit()
var
    FeaturePriceCalculation: Codeunit "Feature - Price Calculation";
begin
    OnBeforeInitPage();
    FeaturePriceCalculation.FailIfFeatureDisabled();
end;

// PurchasePriceLists.Page.al
trigger OnInit()
var
    FeaturePriceCalculation: Codeunit "Feature - Price Calculation";
begin
    OnBeforeInitPage();
    FeaturePriceCalculation.FailIfFeatureDisabled();
end;

// SalesJobPriceLists.Page.al
trigger OnInit()
var
    FeaturePriceCalculation: Codeunit "Feature - Price Calculation";
begin
    OnBeforeInitPage();
    FeaturePriceCalculation.FailIfFeatureDisabled();
end;

// SalesPriceLists.Page.al
trigger OnInit()
var
    FeaturePriceCalculation: Codeunit "Feature - Price Calculation";
begin
    OnBeforeInitPage();
    FeaturePriceCalculation.FailIfFeatureDisabled();
end;

Event Publisher (add at the end of the codeunit with other events):

[IntegrationEvent(false, false)]
local procedure OnBeforeInitPage()
begin
end;
