Calling itemId modified method

Hi,

I created a field on SalesQuotationLine. When filled, then I want to auto populate ItemId based on some logic.

At first, i wrote the code on the modified field of the table to auto populate itemId and it worked. But the other fields that gets populated automatically when filling the ItemId manually weren't filled (like salesCategory, procurment category..etc)

So in the modified field method, after filling the ItemId, i called this.modified(fieldNum(SalesQuotationLine,ItemId));

But it still didn't work. Then i noticed there is code on the modified method of itemId on the formDatasource itself.

So I moved my auto populating code to the formDatasource level instead of table level and called the modified method of the formDatasource. And indeed, it started filling itemId and the other fields when filling this new field. But somehow it cleared the new field that i fill (it seems there is code that clears the line when calling the modified method of the form datasource) so i had to store the original value of the new field and fill it again after calling the modified method. Is there another way?

[ExtensionOf(FormDataFieldStr(SalesQuotationProjTable, SalesQuotationLine, NewField))]
 final class SalesQuotationLineFDS_NewField_Extension
 { 
 public void modified()
 { 
 FormDataObject formDataObject = any2Object(this) as formDataObject;
 FormDataSource formDataSource = formDataObject.datasource();
 SalesQuotationLine salesQuotationLine = formDataSource.cursor();

 NewField newField = salesQuotationLine.NewField;
 
next modified();

 formDataSource.object(fieldNum(salesQuotationLine, ItemId)).modified();
 
salesQuotationLine.NewField = newField; 

 }
}

Calling itemId modified method

If you're sure that keeping NewField value even after resetting the quotation line is the right approach, create an extension of SalesQuotationTableForm.resetSalesQuotationLine(), remember the value before next and put it to _salesQuotationLine again after next. I found this code by looking inside reReadSalesQuotationLine(); you should have done that too to understand the current logic and to be able to design a solution.

Regarding element, you can use it in data source and data source fields extensions to access form variables, including those automatically created for data sources or so. For example, element.vendAdvanceInvoiceTable gives you the current record of VendAdvanceInvoiceTable data source.

Calling itemId modified method

Hi Martin,

where to use "element" can you please explain further?

Also that's the code causing it, but i can't skip it that's why i assigned the value again after calling the modified method.
but i wanted to see if there's a better approach

If I was you, I would debug ItemId.modified() to see where the value disappears.

By the way, you can simplify your code by accessing form variables through the element variable.
