Santanu Karar created FLEX-35190:
------------------------------------
Summary: [FlexJS] DataItemRenderer breaks if extends as MXML file
Key: FLEX-35190
URL: https://issues.apache.org/jira/browse/FLEX-35190
Project: Apache Flex
Issue Type: Bug
Affects Versions: Apache FlexJS 0.8.0
Reporter: Santanu Karar
I took a nightly build of Apache FlexJS and tried by it's supplied
*DataGridExample* example project. The example used a custom DataItemRenderer
class, but it was an ActionScript implementation.
When I tried to create MXML file extending same DataItemRenderer class, when
used to DataGrid component, I couldn't even able to build but thrown by
compiler error:
*1551: Internal error in ABC generator subsystem, when generating code for:
E:\apache-flex-flexjs-0.8.0-bin\examples\flexjs\DataGridExample\src\products\ProductItemRendererMXML.mxml:
java.lang.NullPointerException*
I'm attaching herewith the full error details for your review:
