Warnings when using Accordeon Menu ck

I have check the file in Joomla 3.4.5
ibraries/cms/module/helper.php on line 225 and 242

around line 225 : in my module I call the function like this

so attribs is defined and the line 225 shall not be executed, then even if it does not exists, the line 225 is explicite and force the variable to be created. I don't understand this warning and I wonder if this is really coming from my module. Yes if you are using the accordeon module and loading another module in it you will call this function, but this is the joomla core.

Then I can not reproduce this issue by my side using joomla! 3.4.5 ...

I found the cause finally.

I have are 2 menus using the accordeon modules. One created the errors and one did not. I unpublished all menu items in the one creating the warnings and the warnings went away. Then I published each link one by one. One menu item was causing the warnings. This menu item was an external url and opened a .pdf file in a new window without navigation. If I changed that to new window with navigation or parent, it does not create the warnings. I can live with new window with navigation. Just thought I would let you know my findings.

I had another issue unrelated to your module that appeared with the php upgrade that was related to a plugin called simplepopup. This was cured by unpublishing the plug in. I wasn't using it any longer anyway. There was another one with ossecure as well that I had already fixed. No more warnings or errors now!

Thank you very much for looking into this. If you would like any more info on the issue that I had let me know and I would be happy to test or help in any way that I can.

ok, nice
thank you for the informations
