Redmine

Hi,

I am trying to push tickets from a Lotus Notes Database into Redmine as issues. Therefore I wrote a Java Agent using redmine-java-api-1.19.jar. Creating new issues based on my Notes documents works fine. If I try to update an existing issue in Redmine, however, the RedmineManager throws a RedmineFormatException.

My code:

Issue issueToUpdate = mgr.getIssueById(someIntegerValue);
issueToUpdate.setSubject("something");

// set all the other fields needed

mgr.update(issueToUpdate);

But the exception already occurs at the first line (the given issue ID is correct and it definitely is an Integer type, I double-triple-etc-checked that. I can open the issue in the browser without any problems):

com.taskadapter.redmineapi.RedmineFormatException: org.json.JSONException: A JSONObject text must begin with '{' at 1 [character 2 line 1]

    ... 8 more

I use one custom field into which I put a simple string consisting of numbers and capital letters. No special or reserved characters are used in any field of the issue (as I said, I can open it just fine in Redmine itself), so I am a bit stuck here trying to find out why the JSON-text turns out corrupted. Is there a way to actually see the JSON text the Manager tries to parse? Or might the error be caused by something completely different?

This is the environment used:

Environment:
Redmine version 2.2.2.stable
Ruby version 1.9.3 (x86_64-linux)
Rails version 3.2.11
Environment production
Database adapter Mysql2
Redmine plugins:
redmine_backlogs v0.9.38

I tried it with Redmine Java API 1.18 and 1.19 (same results)

Thanks in advance,
Sarah

EDIT:

I can still retrieve the list of all issues as a JSON object with http:// ... /redmine/issues.json, even the text for the issue that caused the exception mentioned above is correct:

http:// ... /redmine/issues/88.json though returns http error 500. Why?
