Posted on by Norman Elliott - Malta 185

Hi,

I have created a table extension for InventTable and I have added two new string fields. I want to set this field to a default value in the EcoResProductDetailsExtended form which I have extended.

Can some one please advise on how I can do this?

    Hi,

    Please use InitValue method in InventTable and assign your default values which will reflect in EcoResProductDetailsExtended.

    Hi Abbas,

    can you please let me know the syntax to set the WSD field in this method

     [PreHandlerFor(tableStr(InventTable), tableMethodStr(InventTable, initValue))]

       public static void InventTable_Pre_initValue(XppPrePostArgs args)

       {

           // WSD  ? how to set this field

           ;

       }

    Thanks

    Hi Norman,

    For example,  i have two fields created in Inventable called ItemClass and ItemDescription the code is look like below,

    [PreHandlerFor(tableStr(InventTable), tableMethodStr(InventTable, initValue))]

      public static void InventTable_Pre_initValue(XppPrePostArgs args)

      {

         this.ItemClass = WSDItemClass::find(this.ItemId, false).ItemClass;  // this is ex of takeing value from different table based on the itemid... (This line is for example i created myself... use your own table.

         this.ItemDescription = "Direct value assignment";

          ;

      }

    Hi Abbas,

    I created a class called  InventTable_Extension

    Then added this code -->

    [ExtensionOf(tableStr(InventTable))]

    final class InventTable_Extension

    {

       [PreHandlerFor(tableStr(InventTable), tableMethodStr(InventTable, initValue))]

       public static void InventTable_Pre_initValue(XppPrePostArgs args)

       {

           this.

       }    

    }

    'This' does not resolve!

    Can you please advise?

    Thanks

    The error I get is

     'this' is not valid in a static method.

    Sorry my mistake, Write like below,

    [ExtensionOf(tableStr(InventTable))]

    final class InventTable_Extension

    {

      [PreHandlerFor(tableStr(InventTable), tableMethodStr(InventTable, initValue))]

      public static void InventTable_Pre_initValue(XppPrePostArgs args)

      {

           InventTable inventTable = args.getThis() as InventTable;

           inventTable.ItemClass= WSDItemClass::find(this.ItemId, false).ItemClass;

           inventTable.ItemDescription = "Direct value assignment";

      }

    }

    Hi Abbas,

    that compiled and worked well for the creation of new released products.

    I would also like this functionality when viewing existing items.

    What method should I override?

    Thanks for your help.

    Hi Norman,

    InitValue method will work only when you are creating new record. For existing you better use runnable class to update the existing records..

    Hi Abbas,

    the field I have added will be set to the product category top level.

    So, if this product category changes then the InventTable record will need to reflect this change to the user.
