Alexander Koppelhuber commented on BEANUTILS-307:
-------------------------------------------------
ok, you are right
i looked it up in the java beans 1.01 spec
in chapter 8.8 it says:
> BeanUtils.setProperty(...) not working for property "xValue" (see description
> for reason)
> -----------------------------------------------------------------------------------------
>
> Key: BEANUTILS-307
> URL: https://issues.apache.org/jira/browse/BEANUTILS-307
> Project: Commons BeanUtils
> Issue Type: Bug
> Components: Bean / Property Utils
> Affects Versions: 1.8.0-BETA
> Environment: linux, jdk 1.6, beanutils 1.8 beta
> Reporter: Alexander Koppelhuber
>
> setting values for a property that has one lower case character at the
> beginning
> followed by an upper case character does not work. for example "xValue" or
> "zIndex".
> The reason (as far as I found out) is as follows:
> Introspector.getBeanInfo() gets the property names from the get/set methods.
> In Introspector.getTargetPropertyInfo() the following code creates a
> PropertyDescriptor:
> >pd = new PropertyDescriptor(decapitalize(name.substring(3)),......)
> decapitalize(....) says "....when there is more than one character and both
> the first and second characters are upper case, we leave it alone..."
> which results in the name = "XValue" for the method getXValue()
> so setProperty(...) does not find a descriptor for "xValue" and cannot call
> the setXValue method
> I think this issue is not limited to 1.8 beta but also to earlier versions
