Problem with general regord storage page in old pi base extenion

[piotrburda]

TYPO3 7.6.16, comatibility6 and an old pi based extension
Extension in list mode shows only the data from same page (as frontend plugin) it does`t show data from different page (on old 6.2.x it was working)
I'll describe my problem by an example:

1. I have an element with inserted plugin "test" on page pid=5 in backend. This element has no record storage page added by myself(if record storage page for this plugin on page pid=5 exists, then it's default).
2. I'm adding a "test" plugin data on the same page as the plugin. (page pid=5)
3. The "test" plugin shows me the data in frontend. It works.
4. Now, I'm creating a new page pid=6 in backend. Page pid=6 has the same parent in pages tree as page pid=5.
5. I'm adding a element with inserted plugin "test" on the site pid=6.
6. Now it's magic: I set record storage page as page pid=5. I wan't to show on page id=6 the data which is stored on page pid=5.
7. I'm viewing the page pid=6 in frontend in debug mode and there's a problem: the plugin is fetching the data from current page(pid=6), not from the page set as record storage page(pid=5).
   Why?

Hi @piotrburda,

Was the scenario you are referring to working in a TYPO3 6.2 installation? Can you provide some test extension to be able to analyse the issue?
