Description Filip Brychta 2012-04-20 03:13:26 EDT
Description of problem:
pretty.print(childResources); failed to print output however print(childResources); works correctly. See attached test.js

Version-Release number of selected component (if applicable):
Version: 4.4.0-SNAPSHOT
Build Number: ca5eecb

How reproducible:

Steps to Reproduce:
1. import Linux platform resource with all child resources to your inventory
2. run ./rhq-cli.sh -u rhqadmin -p rhqadmin -f test.js > output.txt
Actual results:
see attached output.txt

Expected results:
output of pretty.print(childResources) should not be empty

Additional info:
test.js and output.txt attached
It seems that pretty.print fails with set of resources, for single resource works correctly.

Comment 4 Filip Brychta 2013-02-27 08:49:07 EST
I run into this again today.
pretty.print failed to print PageList<ResourceOperationHistory> so the output of following code:

var resOpHistCri = new ResourceOperationHistoryCriteria();
var hist = OperationManager.findResourceOperationHistoriesByCriteria(resOpHistCri);

is empty.

Workaround for this is:

I tracked this down and eventually found the root cause.  I can't really explain it, must be a subtle issue with I/O.

    Very strange issue. Replace out.print("\n") with out.println() calls
    seems to solve the problem.
