Description Tamas Szabadi 2016-09-13 09:32:31 UTC
If the delimiter is set up for tab, the dashboard cannot be generated.

Steps to reproduce:

1. Use the following property for setting up the tab in the user.properties:


2. Try to run and generate the dashboard. 

Expected result:

Report dashboard should be generated.

Actual result:

The following error appears:

Writing log file to: d:\apache-jmeter-3.0\bin\jmeter.log
Creating summariser <summary>
An error occurred: null
Press any key to continue . . .

In the jmeter.log the following exception happens:

2016/09/13 02:27:48 INFO  - jmeter.JMeter: Creating summariser <summary>

It seems that when in the ReportGenerator.java file the property is read like this:

private static final char CSV_DEFAULT_SEPARATOR =
            JMeterUtils.getPropDefault("jmeter.save.saveservice.default_delimiter", ",").charAt(0); //$NON-NLS-1$ //$NON-NLS-2$

And getPropDefault will trim the value before returning, so the tab will be trimmed down, and then charAt(0) will be called for an empty string.

Let me know if you need any more information.
