[opencms-dev] Comments module:

[Olli Aro]

Well you get a nullpointer on this line:

if ((getConfig().getList() <= 0) || (countCmts == 0)) {

The only possibility for null here is the getConfig() method, which gets your comment configuration file.

So, it looks like there is definitely problem with your configuration file. Not sure what to suggest if you do have your config file at /data/config.html and you are trying to view page within the same site scope.

Regards,

Olli

HI
I have the same error. I've look at the stacktrace and I've got this:

java.lang.NullPointerException
	at com.alkacon.opencms.comments.CmsCommentsAccess.getPages(CmsCommentsAccess..java:574)
	at com.alkacon.opencms.comments.CmsCommentsAccess.init(CmsCommentsAccess.java:684)
	at org.opencms.jsp.CmsJspLoginBean.<init>(CmsJspLoginBean.java:95)


I've looked at the source code but it's not easy to read all the code!!! Error is somewhere in the .getPages() function...


(I'm on OpenCms705 and my config file is under a /sites/website/ I've configured in the opencms-system.xml file. My property "comments" point on my config file: /data/config.html.)

Ok, not quite sure then. We have been running this module in testing couple of weeks not with no problems. One further idea, are you testing your module within a subsite scope (so your comments properly is not set to /sites/default/comments.xml but /comments.xml), since that might make a difference?

Other than that, maybe you could try to catch the exception in the JSP, so we could see the full stacktrace?

Olli

I checked the comments-property several times also starting the path
with / and without.
