If I set $FieldProperties on a read to store an original value and never set $FieldProperties again for the field, my value is retained.

However, after setting the value, if I store another property, such as BackColor, my original value property disappears.


Example:

In initial Proc:

$FieldProperties(Receipt_Volume.Table_Name) = "OriginalValue=%%nReceiptVolume%%%"


In some other Proc :

sProperties = $FieldProperties(Receipt_Volume.Table_Name)

GetItem/Id nNomOriginalValue, sProperties, "OriginalValue"

-- Works just fine


In another Proc to change BackColor if data has changed:

$FieldProperties(Receipt_Volume.Table_Name) = "BackColor=SomeColor"

-- Set BackColor ok, but OriginalValue is lost

-- Anywhere afterwards sProperties = $FieldProperties(Receipt_Volume.Table_Name) only has BackColor Info

Hello Rob,

The described behavior is normal. With the mentioned statement you always overwrite all field properties. In case you only want to update one (or more) specific properties then you need to specify this with the PropertyList parameter. E,g,


$FieldProperties(Receipt_Volume.Table_Name, "OriginalValue") = "OriginalValue=%%nReceiptVolume%%%"
$FieldProperties(Receipt_Volume.Table_Name, "BackColor") = "BackColor=SomeColor"


For more details see the doc:

I hope this helps.

Kind regards,

Hi Rob,

As you have discovered setting the value of $fieldproperties you replace all the current values

There are a number of ways of achieving what you are looking for

  1. Add to or replace an item in the list
    putitem/id  $FieldProperties(Receipt_Volume.Table_Name), "BackColor", "SomeColor"
  2. Specify the item(s) to replace
    $FieldProperties(Receipt_Volume.Table_Name, "BackColor") = "BackColor=SomeColor"

Regards,

Mike

Hi Rob

$fieldproperties (and other "proerties" too)  are just simple UnifAce-Item-Lists (UIL)
So you can modifiy/read them by

  • putitem/id
  • delitem/id
  • getitem/id
  • $item()
  •  ..and so on

Thank you all!  Working great now.  Been working with Uniface for 21 years and just recently began making use of the advanced Properties.
