Simple way of using 1 and 0 values in a boolean field

[fatzopilot]

Hi,

I've got an xml DS (client only) that has a tag like this:

<b>1</b>

containing either 1 or 0.
I'd like to represent this as a DataSourceBooleanField in a ListGrid.
Simply declaring a boolean Field raises this warning:

[ERROR] [myApp] - 16:38:28.362:TMR6:WARN:DataSource:BoolDS$499:BoolDS$499.x: value: "1" failed on validator: {type: "isBoolean",
typeCastValidator: true,
_generated: true,
defaultErrorMessage: "Must be a true/false value.",
resultingValue: false}

The field is always rendered as a "disabled true" in the ListGrid, i.e. as a gray checked checkbox, regardless whether it is 0 or 1. Using it to filter the records using a criteria query works, however.

This does not occur if true/false is used rather than 1/0.
Is there a simple way to rectify this?

Thanks,

We would suggest using actual boolean true/false values client-side, and using dataSourceField.sqlStorageStrategy to map to underlying database storage.

Hi,

thanks for your response, however, the DS is client only and just displaying a read-only XML file.
Is there some value path expression maybe that could do the trick?

You could add a FieldValueExtractor, or transformResponse() implementation if it's multiple fields.

FieldValueExtractor was the missing piece, thanks for the Pointer!
