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

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.

Hi
As you said, you have backup the project, it should contain the context files, try to import them into new project from the backup.

Is there anyway that I can recreate all these context data automatically since they are used in job design.

No, you have to import them or recreate them.
Best regards
