<p>Hello,</p>
<p> </p>
<p>I have a report that runs fine in BIRT viewer 3.7.2. I'm working through all my reports migrating them to BIRT 4.5 and using MySQL 5.7. When I run this one report in the 4.5 viewer, it gives a java.lang.nullpointerexception and gives a stacktrace. However, it's not enough information (usually these things don't give enough information in the web viewer). I see that the preview function has been removed in newer BIRT releases, but I used to rely on that in cases like this for more information about where the exception was being thrown. How can I get more information about this issue? Is there an error log somewhere that I can access?</p>
<p> </p>
<p>In case it helps, I did happen to narrow down the exception to line 3 of this code:</p>
<pre class="_prettyXprint _lang-js _linenums:1">
// get the DelinquentDuesTable handle to be used for setting its sort direction
table = reportContext.getDesignHandle().findElement("DelinquentDuesTable");
table.getListProperty("sort").get(0).setProperty("direction",params["sortDirection"].value);
</pre>
