Bug in assigning converters [message #1031935]

Hello,

I am using NatTable version 0.9.0 and I want to use my own converter as shown in the documentation. There is, however a bug in the code.

For this reason, I have created a new converter:

public class NewBigDecimalConverter extends DefaultDisplayConverter {
	@Override
	public Object canonicalToDisplayValue(ILayerCell cell,
			IConfigRegistry configRegistry, Object canonicalValue) {
		return "Test";
	}
}

I am also adding the converter to every cell. There are no other converters in the application:

configRegistry.registerConfigAttribute(
	CellConfigAttributes.DISPLAY_CONVERTER, 
	new NewBigDecimalConverter(),
	"BODY"
	);

I have also checked the cells. They have the required labels (255255255 is another label):

Labels:
255255255
EVEN_BODY
BODY

However, my converter is not called. Every cell shows the original value (a big decimal number) and not my converted value. Any chance to debug this one even further?

Regards,
Clemens

I don't think there is a bug. Otherwise everybody who uses NatTable wouldn't ever be able to use converters.

Usually this is caused because you either register your special configuration too late or not at all. Where and when do you add the configuration that registers your converter?

You are completely right. The configuration took place after the table had been shown once. Since there was no refresh, the converter could not work.
I am very sorry for the hassle!
