> ClassCastException on Entity update
> -----------------------------------
>
> Key: OLINGO-45
> URL: https://issues.apache.org/jira/browse/OLINGO-45
> Project: Olingo
> Issue Type: Bug
> Components: odata2-jpa
> Affects Versions: V2 1.0.0, V2 1.1.0
> Reporter: Georgi
> Assignee: Chandan V.A
> Fix For: V2 1.1.0
>
>
> You might want to doublecheck the logic in
> org.apache.olingo.odata2.processor.core.jpa.access.data.JPAEntity:write(final
> Map<String, Object> oDataEntryProperties, final boolean isCreate)
> On line 141 there's an explicit cast to List<ODataEntry>. However I found out
> that during update, when the property is a 1:1..0 relation to another Entity,
> the returned type is ODataEntry. And that causes the ClassCastException.
> I managed to solve this for me with a simple if/else block:
> List<ODataEntry> relatedEntries = null;
> if(oDataEntryProperties.get(propertyName) instanceof ODataEntry){
> relatedEntries = new ArrayList<ODataEntry>();
>
> relatedEntries.add((ODataEntry)oDataEntryProperties.get(propertyName));
> } else {
> relatedEntries =
> (List<ODataEntry>)oDataEntryProperties.get(propertyName);
> }
> The code is from the 1.1.0-SNAPSHOT master branch HEAD.
> I hope that helps.
