Lukasz Lenart updated WW-3427:
------------------------------
Fix Version/s: 3.x
> If you alias a property that uses a custom TypeConverter and it throws
> TypeConversionException the error is never caught
> ------------------------------------------------------------------------------------------------------------------------
>
> Key: WW-3427
> URL: https://issues.apache.org/jira/browse/WW-3427
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors
> Affects Versions: 2.1.8.1
> Environment: Windows
> Reporter: Sloan Seaman
> Labels: conversion, struts, type
> Fix For: 3.x
>
>
> 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()
>
