ExtWebUpdatePage

Scoped name

WSYEXTJS/ExtWebUpdatePage

Note that this abstract function is placed in the WSYEXTJS model.

Purpose

This is an abstract PageGenerator that can be used if you want to have an update page outside a WebEditSuite. This page is designed for use in the Ext JS for WebsydianExpress framework.

The PageGenerator includes two EventHandlers: Update and Cancel. The Update EventHandler validates the record by calling a separate validation function (scoped by the ServiceFunctions function). This function performs the standard validation based on the Plex definitions. If the validation succeeds, the record is updated.

Usage

You must start by creating a function that inherits from ExtWebUpdatePage:

Source Object Verb Target Object
MyUpdatePage is a FNC WSYEXTJS/ExtWebUpdatePage

Then you must specify the entity to update records for by replacing the UIBasic.Update view with your own Update view - and the UiBasic.Detail view with your Fetch view

Source Object Verb Target Object
MyUpdatePage replaces VW

...by VW

 UIBASIC/UiBasic.Update

MyEntity.Update
MyUpdatePage replaces VW

...by VW

 UIBASIC/UiBasic.Detail

MyEntity.Fetch

Finally, you must enter calls to a PageGenerator in the Update and Cancel EventHandler.

Special considerations

In many cases, you will get the update page as part of a WebEditSuite - either by inheriting from ExtWebEditDialog or from ExtWebEditSuite.

You can customize the validation by making  changes to the MyUpdatePage.ServiceFunctions.Validation function. This function inherits from WSYAPI/Abstract.ValidationFunction
