Richard Eckart de Castilho commented on UIMA-3776:
--------------------------------------------------
MetaDataObject_impl.getAttributes() does not automatically detect the attribute
"delegateAnalysisEngineSpecifiers" because it has no setter.
AnalysisEngineDescription_impl.getAdditionalAttributes() does not return
"delegateAnalysisEngineSpecifiers", only
"delegateAnalysisEngineSpecifiersWithImports".
However, AnalysisEngineDescription_impl.writePropertyAsElement(PropertyXmlInfo,
String, ContentHandler) has the following logic:
{noformat}
String propName = PROP_DELEGATE_ANALYSIS_ENGINE_SPECIFIERS;
if (mDelegateAnalysisEngineSpecifiers.isEmpty()) {
propName = PROP_DELEGATE_ANALYSIS_ENGINE_SPECIFIERS_WITH_IMPORTS;
}
writeMapPropertyToXml(propName, ELEM_DELEGATE_ANALYSIS_ENGINE_SPECIFIERS,
"key",
"delegateAnalysisEngine", aPropInfo.omitIfNull, aNamespace,
aContentHandler);
{noformat}
Note that writeMapPropertyToXml uses MetaDataObject_impl.getAttributes()
internally. Thus, after resolving imports and thus causing
mDelegateAnalysisEngineSpecifiers not to be empty anymore, the delegates are no
longer serialized because writeMapPropertyToXml has no access to
"delegateAnalysisEngineSpecifiers".
It should be save to e add a read-only attribute for
delegateAnalysisEngineSpecifiers to AnalysisEngineDescription_impl using
getDelegateAnalysisEngineSpecifiers() as a getter method.

> Project: UIMA
> Issue Type: Bug
> Components: Core Java Framework
> Reporter: Richard Eckart de Castilho
> Fix For: 2.6.0SDK
>
>
> This is a regression in the UIMA SDK 2.6.0 RC 1 and worked in UIMA SDK 2.5.0.
> * Add a full delegate description to an AAE.
> * Serialize to XML: delegate description is serialized.
> * Call resolveImports()
> * Serialize to XML: delegate description is no longer serialized.
