Converter Filter
Use the Converter Filter part to convert incoming form data into a Smalltalk object. This part is useful because data submitted from a form always arrives in string format.
To use the Converter Filter part, first set the Converter Filter's converter property to the appropriate converter for the type of object you want to convert the data into. Then connect the incoming string data to the Converter Filter's string attribute. The Converter Filter's object attribute represents the Smalltalk object resulting from the conversion.
If the incoming string data cannot be converted to the specified data type, the errorMessage attribute contains an error message string.

object
Use the object property to set the initial value of the Converter Filter's object attribute. The initial value must be compatible with the converter type specified by the converter attribute.
partName
In the Part name field, type the name you want to use to describe the part. For non-visual parts, this text appears under the icon for the part on the free-form surface.
The name of the part can consist of alphanumeric characters, and must be unique from all other parts on the layout surface.
This field is optional. If you do not specify a part name, VA Smalltalk generates a unique name based on the class name of the part.
