Export of Ad Hoc View Based On Topic Failes With 'URI ... was not found in the repository'

Issue Description

We created Ad Hoc View from a topic.

The View works without any issues but when we try to export it from the repository (right-click and select Export context menu), we get

'Export failed. The server has encountered an unexpected error' message in JasperReports Server UI.

TIBCO JasperReports^® Server log file contains exception like

' Export failed:
com.jaspersoft.jasperserver.export.service.ExportFailedException: URI /organizations/organization_1/adhoc/topics/OrdersTopic_files/OrdersTopic_files was not found in the repository'

What is the reason of the error and how to fix it?

Resolution

As it turned out, the Topic in question used so-called 'Local Datasource' instead of a link to a datasource stored in the repository:

Topic Local datasource details are stored inside the topic internal definition.

As a result, when a user tries to export Ad Hoc View based on such topic, export process can't locate datasource details (in topicName_files folder)

and failes.

While the issue is not fixed, a workaround is to use a datasource stored in the repository.

Solution tested with TIBCO JasperReports^® Server v.6.4.0, 6.4.2
