NullpointerException when decorator content is processed
--------------------------------------------------------
Key: OFBIZ-4323
URL: https://issues.apache.org/jira/browse/OFBIZ-4323
Project: OFBiz
Issue Type: Bug
Components: framework
Affects Versions: SVN trunk
Reporter: Javier Orrantia
Hi Everybody,
I am deploying my application from trunk version: 768631 to version: 1134255
and I am get a nullpointer exception when I try to run my web application as
shown below.
I have traced this problem and found that this is happening when the the
decorator data-resource is processed. My website has a content with a content
decorator assigned. It seems that when the decorator content is processed, the
DOM parser does not set the following userData (setUserData method):
startColumn, startLine. I have made a temporary fix by changing the
ModelWidget.java and ignoring the startColumn and startLine userData from the
processed DOM object.
Can somebody take a look at this?
Thanks,
Javier Orrantia
