Changed behaviour in APEX5: APEX_PLUGIN_UTIL.CLEANUP_PAGE_ITEM_NAMES

Unfortunately some things have to be learned in a hard way.

As I'm doing another APEX 4.2 to APEX 5 migration I just learned that there's changed behaviour in function apex_plugin_util.cleanup_page_item_names. Unfortunately, not documented.

If you take a closer look at function source you may see that there's additional call to REPLACE function that replaces double commas with single one:

So, in APEX 4.2 query

will result with

P1_ITEM1,,P1_ITEM2

and in APEX 5

P1_ITEM1,P1_ITEM2

Hope that this will save some debug time to somebody! :)
