Thomas Bonk updated OLINGO-1263:
--------------------------------
Description:
If you try to filter an entity set with the filter {{$filter=()}}, HTTP Status
Code 500 and the error message
<?xml version='1.0' encoding='UTF-8'?>
<error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata";>
<code/>
<message xml:lang="en">while trying to invoke the method
org.apache.olingo.odata2.api.uri.expression.CommonExpression.getKind() of a
null object loaded from local variable 'leftNode'</message>
</error>
is returned.
Expected behaviour:
Either return HTTP Status Code 400 with an error message like "Invalid filter
expression '()'" or return HTTP Status Code 200 with the unfiltered entity set.
How to reproduce:
Create the my-car-service sample:
mvn archetype:generate \
-DinteractiveMode=false \
-Dversion=1.0.0-SNAPSHOT \
-DgroupId=com.sample \
-DartifactId=my-car-service \
-DarchetypeGroupId=org.apache.olingo \
-DarchetypeArtifactId=olingo-odata2-sample-cars-annotation-archetype \
-DarchetypeVersion=RELEASE
Deploy the service and do a request using the URL
http://<hostname>:<port>//my-car-service/CarService.svc/Cars?$filter=()
