Hi Team,

There is no customization , its just oob.

I have exactly the same issue. Can't understand why.

Looking forward some responses.

Thank you

Hello Eric,

I guess by increasing the size of heap on server resolve our problem.

You can try with the same,hope you will get it right way.

Hi Sagar,

Hi Sagar,

Can you provide your memory settings here?

Thanks,
Roshan Qureshi

Roshan,

Actually problem was not related memory in this case,

We have multiple webapps are deployed on server when you export it will keep a track on page id plus portlet id on that page.

When we are trying to import lar any how it was trying to look pid with given portlet because of that it was throwing error.

I will give you detail if you require.

Hi Nrupay,

As of now I know only following

We have multiple webapps are deployed on server when you export it will keep a track on page id plus portlet id on that page.

When we are trying to import lar any how it was trying to look pid with given portlet because of that it was throwing error.

But if you want more information , certainly I will try to get it from my team and get back to you.

Hi,

I had faced same issue on dev server and found the solution :

Error clearly shows there is some issue with some portlet instantiate.
It was crashing at method getPortletDataHandlerPortlets in LayoutExporter.java, there is no debug/info statements in this method.

1. Create Groovy script (PFA-Groovy Script) and find out which portlet is having problem in instantiate and undeploy that portlet. (In my case that portlet was not in use, if its in use then we should undeploy and deploy it again).
2. Reindex and restart the server.

Then It works fine.

Thanks,
Hemen

Hi Sagar,

Can you please share the solution to this issue? For me this is happening only on Linux server. On windows the same code runs fine.

I am getting the issue while deleting a group from Control Panel.
