how to validate editable text in the cell table

[abdul]

image which is of editable textinputcell

want to validate the columns if its number of colleges then user can enter 
only number(integer cell) and for name of college user can enter only 
string(text cell). Is there a way to validate before entering the text into 
inputcell?

JsInterop @JsFunction lambda$0 is not a function in some cases

[DavidN]

Hi,

I'm having some issues with JsInterop in 2.8 snapshot. When I try to use a 
JsFunction I get an exception, depending on where I declare a lambda for 
the JsFunction.

I have a JsType defined like this:

@JsType(isNative = true, namespace = JsPackage.GLOBAL, name = "Object")
public class ChartConfig {
  public double value;
  public CurrentFunction showCurrent;
  public ChartConfig() {
  }
  @JsOverlay
  public final ChartConfig showCurrent(CurrentFunction pFormatter) {
showCurrent = pFormatter;
return this;
  }
  @JsOverlay
  public final ChartConfig showCurrent() {
showCurrent = text -> text;
return this;
  }
  @JsOverlay
  public final ChartConfig hideCurrent() {
showCurrent = null;
return this;
  }
  @JsFunction
  public static interface CurrentFunction {
String format(String pValue);
  }
}



When I use the first showCurrent method with a lambda everything works fine:
ChartConfig = config = new ChartConfig();
config.showCurrent( t->t);


When I use the second showCurrent method, which should be the same, I get 
an exception:
ChartConfig = config = new ChartConfig();
config.showCurrent();
