Error to get PortletConfiguration from PortletConfigurationManager

[Carlos Ivan Martin [DEISER]]

Hi guys!

I'm trying to get a list of PortletConfiguration from PortalPage, with the following manager: PortletConfigurationManger, and trying to use "getByPortalPage(Long idPortalPage)" method of the manager.

However, in some cases, I find that this method throws an exception: StringIndexOutOfboundsException.

I have tried to delete all PortalPages for the user with this problem, but I can't do it, I have had an error.

I do not understand the reason for the error, as it is an Id given by Jira and should exist. Does anyone know what this mistake is and how I could fix it? 

Thanks in advance

Regards

Carlos
