Subject [jira] [Commented] (CXF-7213) FIQL Parser: Crashes when parsing a collection (java.util.Set) inside an object
Date Wed, 18 Jan 2017 18:09:26 GMT

    [ https://issues.apache.org/jira/browse/CXF-7213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15828489#comment-15828489

Hector Kikuchi Martins commented on CXF-7213:
---------------------------------------------

After some debbuging I found out that maybe several parsers may have the same issue, since
the "crash" occurs on the class: AbstractSearchConditionParser on rt-rs-extensions-search
project.

The follow attribution on line 214:
Object valueObjectValue = lastTry || !returnCollection 
                    ? nextObject : getCollectionSingleton(valueType, nextObject); 

The parameter valueType is not an Collection an thus, the getCollectionSingleton method will
always return Collections.singletonList() which is an List, crashing the reflection invoke
to an setter to a java.util.Set.

I cloned the repository and switched the parameter valueType to returnType and fixed my issue,
but since I don't have enough knowledge on the whole project, I didn't know if it can cause
any other collateral bug.
