Codegen: Enumeration in imported schema can result in IllegalArgumentException:
No enum const class
---------------------------------------------------------------------------------------------------
Key: JIBX-263
URL: http://jira.codehaus.org/browse/JIBX-263
Project: JiBX
Issue Type: Bug
Components: core
Affects Versions: JiBX 1.2
Reporter: Nigel Charman
The problem occurs when a complex-type containing a string with an enum
restriction is imported from another schema. It happens consistently in one
project, but I've been trying for most of the afternoon to reproduce it in a
simpler form and can't make it fail outside the original project.
The project uses 4 schema. Schema C imports schema D. Schema A imports both
schema C and D. Schema B also imports both schema C and D. Schema D contains
<xsd:simpleType name="version">
<xsd:restriction base="xsd:string">
<xsd:enumeration value="3.2"/>
<xsd:enumeration value="3.3"/>
<xsd:enumeration value="4.0"/>
</xsd:restriction>
</xsd:simpleType>
The generated binding.xml includes the bindings in the "wrong" order:
<include path="binding D"/>
<include path="binding C"/>
<include path="binding B"/>
<include path="binding A"/>
binding A contains:
<format type="Version" enum-value-method="value"/>
bindings C and D contain:
<value style="attribute" name="Version" get-method="getVersion"
set-method="setVersion"/>
However, since C and D are included before A in binding.xml, they do not seem
to know about the format of the Version enum. The resulting error is:
[java] Exception in thread "main" java.lang.IllegalArgumentException: No
enum const class xsd.simpletypes.Version.3.2
[java] at java.lang.Enum.valueOf(Enum.java:196)
[java] at xsd.simpletypes.Version.valueOf(Version.java:16)
[java] at xsd.svreq.MESSAGE.JiBX_binding_unmarshalAttr_1_0(MESSAGE.java)
[java] at xsd.svreq.JiBX_bindingMESSAGE_access.unmarshal()
[java] at
org.jibx.runtime.impl.UnmarshallingContext.unmarshalElement(UnmarshallingContext.java:2762)
[java] at
org.jibx.runtime.impl.UnmarshallingContext.unmarshalDocument(UnmarshallingContext.java:2905)
[java] at Test.main(Test.java:25)
I can work around the issue by either adding the <format type="Version"
enum-value-method="value"/> element to bindings C and D, or rearranging
binding.xml to have the bindings in the order A, B, C, D. When I try to
reproduce the error in a simplified project, the code generator always seems to
create the binding.xml in the order A, B, C, D.
I can email you the project, but don't want to upload it publicly.
