[overlord-issues] [JBoss JIRA] (ARTIF-656) Cannot query with 2 relationship predicates

Cannot query with 2 relationship predicates ------------------------------------------- Key: ARTIF-656 URL: https://issues.jboss.org/browse/ARTIF-656 Project: Artificer Issue Type: Bug Reporter: Brett Meyer Assignee: Brett Meyer Fix For: 1.0.0.Alpha2 Example: {code} /s-ramp/wsdl/Part[relatedDocument[@uuid = '%1$s'] and element] {code} That currently results in something like: {code} SELECT artifact1.* FROM [sramp:baseArtifactType] AS artifact1 INNER JOIN [sramp:relationship] AS relationship2 ON ISCHILDNODE(relationship2,artifact1) INNER JOIN [sramp:target] AS target3 ON ISCHILDNODE(target3,relationship2) INNER JOIN [sramp:baseArtifactType] AS artifact4 ON target3.[sramp:targetArtifact] = artifact4.[jcr:uuid] INNER JOIN [sramp:relationship] AS relationship5 ON ISCHILDNODE(relationship5,artifact1) WHERE artifact1.[sramp:artifactType] = 'Part' AND relationship2.[sramp:relationshipType] = 'relatedDocument' AND artifact4.[sramp:uuid] = 'cea13510-e7a6-4195-a18e-c091eb5a939e' AND relationship5.[sramp:relationshipType] = 'element' AND ISDESCENDANTNODE([sramp:baseArtifactType],'/s-ramp' {code} Since we use an artifact -> relationship -> target structure, and since ModeShape doesn't allow you to use the selectors transitively (ie, can't use "artifact1" in a subselect), inner joins were the method used. Each time a relationship predicate is hit, the parser assumes "I need to join and add a condition". Forgetting the parser, for a moment, I'm not sure what the eventual query should look like...
