Description Filip Brychta 2012-04-20 07:13:26 UTC

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:
Always

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.

Investigate for easy/hard this would be to address

setting priority to medium per BZ triage 4/23 (crouch, santos, oleary, foley)

Comment 4 Filip Brychta 2013-02-27 13:49:07 UTC

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);
pretty.print(hist)

is empty.

Workaround for this is:
for(i=0;i<hist.size();i++){
	pretty.print(hist.get(i));
}

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.
