Help on NullPointerException When open existing project
I have finish design all jobs for my project and also finished testing.
While today when open existing project, following error occurs:
java.lang.NullPointerException

System version is as follows:
OS: Windows 2007 Enterprise
Java: 1.5.0_17
Talend: TOS-Win32-r53616-V4.1.2.exe
Could anyone here please help me out on this? It is really urgent and important.
I installed talend in another computer and created a new Project. and copy following configurations from original workspace to new project as follows:
---------------------------------
1. context
2. metadata/connections
3. process
---------------------------------
And refreshed the Design View.
It is Ok for 2. metadata/connections & 3. process.
While error occurs when open context. And the error is as follows, could anyone help on this?

Hi
Try to import the items into the new project from old workspace, right click on the Job Design and select 'import items' option.
Let me know if you have any questions!
Best regards
Shong
Hi Shong,
Thanks,
Actually I exported Items by click "Job Design" -> "Export Items" in original project several days ago.
There are altogether about 20 jobs with context and db connection metadata.
While in the newly created project. Right lick "Job Design" -> "Import Items", it appears "no valid items found in source"
While if I unzip the exported items. there are corresponding .item & .properties files under process, metadata/connections, context.
I am not sure what's wrong with it?
As for work-around for this issue I have copied individual files (.item & .properties) under process, metadata/connections, context and refresh design view. All are ok except for contexts. So I think the route cause of the error is something wrong with context files. Do you have any suggesion on this? Is there anyway that I can recreate all these context data automatically since they are used in job design.
