-----------------------------------
Summary: camel-google-sheets - spreadsheets/sheets, values and
developerMetadata fail with a ClassCastException, and the splitResult option
has no effect
Key: CAMEL-26243
URL: https://issues.apache.org/jira/browse/CAMEL-26243
Project: Camel
Issue Type: Bug
Components: camel-google-sheets
Reporter: Claus Ibsen
Fix For: 4.24.0
Found while adding the catalog body types of google-sheets and
google-sheets-stream (CAMEL-24961, PR #28403).
h4. 1. spreadsheets/sheets, spreadsheets/values and
spreadsheets/developerMetadata fail with a ClassCastException
The generated {{SheetsSpreadsheetsApiMethod}} (main 2a465aa4814c, lines 36, 54
and 58) lists the accessors {{Spreadsheets.developerMetadata()}}, {{sheets()}}
and {{values()}} as methods. They return a sub-resource, not a request, so
{{GoogleSheetsProducer.doInvokeMethod}} (lines 43-44) fails with
{{ClassCastException: ... cannot be cast to AbstractGoogleClientRequest}}; the
consumer ({{GoogleSheetsConsumer}}, line 41) the same. Checked on
4.24.0-SNAPSHOT with a fake {{MockHttpTransport}} client set through
{{clientFactory}} for spreadsheets/sheets; values and developerMetadata have
the same pattern (read in the code). The values methods themselves are
reachable as the separate {{data}} API.
Proposed: leave the sub-resource accessors out of the generated methods (or
exclude them in the {{pom.xml}}).
h4. 2. The splitResult option has no effect
The {{splitResult}} option of google-sheets (consumer, documented default true:
"one exchange per element") never splits anything: no google-sheets method
returns an array or collection ({{Spreadsheet}}, {{ValueRange}},
{{BatchGetValuesResponse}}... are single model objects), so
{{ApiConsumerHelper.getResultsProcessed}} always sends one message. One message
per row needs google-sheets-stream with {{splitResults}}. Checked on
4.24.0-SNAPSHOT with the fake client.
Proposed: document that the option does nothing for google-sheets (or hide it).
(The default of {{AbstractApiConfiguration.splitResult}}, false where true is
documented, is fixed by CAMEL-26025.)
