Description

If you define an alias to a property like so:

@Actions({
  @Action(
    value="/icc/saveScan",
    interceptorRefs=@InterceptorRef("ptiDefault"),
    results={
      @Result(name="input", location="/error.jsp"), 
      @Result(name="success", location="/success.jsp")
    },
    params={"aliases", 
      "#{\"plateId\" : \"plate\", " +
        "\"machineAbbr\" : \"machine\", "+
        "\"imageFiles\" : \"scanData\"}"
    }
    */
  )
})

and the property (say imageFiles/scanData) has a custom TypeConverter configured like so:

	@ConversionErrorFieldValidator(type = ValidatorType.FIELD, 
		key="invalid.fieldvalue.xxx",
		message = "well not found or imageFiles not in format: file,wellId|file,wellId|...",
		shortCircuit=true)
	@TypeConversion(rule = ConversionRule.COLLECTION, 
		converter = "com.ptilabs.icc.action.ScanData")
	public void setScanData(List<ScanData> imageFiles) {
		this.imageFiles = imageFiles;
	}

{

If the TypeConverter throws a TypeConversionException the exception is never caught by the ConversionErrorInterceptor or ConversionErrorFieldValidator.

If I disable the aliasing and rename the method setImageFiles everything works correctly.

I'm trying to debug on my own but I can't find the class responsible for catching the TypeConversionException and placing it in the invocationContext.getConversionErrors()
