[jira] [Commented] (JENA-1739) Using Path in UpdateBuilder#addWhere
throws an Exception
[ https://issues.apache.org/jira/browse/JENA-1739?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16902981#comment-16902981 ]
Claude Warren commented on JENA-1739:
-------------------------------------
This is a but isolated to the UpdateBuilder. Code needs to be added to test for predicate being an path object for 3-argument methods addWhere, addOptional and addDelete as well as the 4-argument addDelete method.
For completeness 4 methods should be added addDeletePath( Iterator<TriplePath> ), addDeletePath( Collection<TriplePath> ) , addInsertPath( Iterator<TriplePath> ) and addInsertPath( Collection<TriplePath> )
> Using Path in UpdateBuilder#addWhere throws an Exception

> Project: Apache Jena
> Issue Type: Bug
> Components: ARQ
> Affects Versions: Jena 3.10.0
> Reporter: Vadim Gubin
> Assignee: Claude Warren
> Priority: Major

> java.lang.IllegalArgumentException: Predicate ("[some path here, for example (S|^S)/((S|^S))?]"^^java:org.apache.jena.sparql.path.P_Seq) must be a Path, URI , variable, or a wildcard.
> Is a prefix missing? Prefix must be defined before use.

> h4. How to reproduce:
> Path path = createSomePath()...
> UpdateRequest update = new UpdateRequest(new UpdateBuilder()
> .addWhere(subject, path, object)
> .build());
>
> RDFConnectionRemoteBuilder connectionBuilder = connectionBuilderFactory.createConnectionBuilder();
> try (RDFConnection connection = connectionBuilder.build()) {
> connection.update(update);
> }
> h4. Workaround:
> .addWhere(new TriplePath(subject, path, object));
