[jira] Updated: (TUSCANY-1429) Using default helper context got
ClassCastException due to T-1317
[ https://issues.apache.org/jira/browse/TUSCANY-1429?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Fuhwei Lwo updated TUSCANY-1429:
--------------------------------
Attachment: 1429.patch
Uploading 1429.patch to fix this problem by forcing commonj.sdo.HelperProvider from the spec to instantiate Tuscany's HelperContextImpl for the default helper context. This would allow us to cast the HelperContext to HelperContextImpl whenever we need to access Tuscany specific information like XMLStreamHelper.
I also took the liberty to clean up client APIs such as SDOHelper, SDOHelperImpl, api.SDOUtil, and util.SDOUtil to use HelperContext as scope instead of TypeHelper and XSDHelper. The approach I am taking is to deprecate APIs with TypeHelper/XSDHelper parameters and create new ones with HelperContext. I also fixed test cases using those newly deprecated APIs. Please review. Thanks.

> Starting from T-1317, we started to use HelperContext as the scope instead of TypeHelper or XSDHelper. The ClassCastException problem starts to appear when we need to cast HelperContext to HelperContextImpl to access the XMLStreamHelperImpl which is not a spec compliant Helper because the default helper context is not an instance of HelperContextImpl.
