Switching from FPM_LIST_UIBB to FPM_LIST_UIBB_ATS visibility issue

[dm_mt]

Hello Everybody.

While trying to replace one standard MDG-C UIBB: Relationships from using FPM_LIST_UIBB to FPM_LIST_UIBB_ATS motivated by old but very informative blog post "** TEAM FPM ** – Switching from the Old List UIBB to the New List UIBB (aka List ATS UIBB)" from ulrich.miller#overview, I have faced situation where new UIBB not being shown at all on overview page, no matter what I tried.

Both old and new versions have standard configurations, BS_BP_RELATIONS(FPM_LIST_UIBB) and BS_BP_RELATIONS_ATS(FPM_LIST_UIBB_ATS).

Both of them have in attributes Hidden Element: Visible

Also, I've created wire for ATS, as below

Backwards wire, namely from detail page to list I was not able to create because of error with multiple assignment, which was not allowed as per error, but anyways not reached any navigation, therefore doubt that this is the issue.

Additionally I've tried to reset all personalizations, was even switching them off but it did not had any effect.

* one more update: also, I've checked if there any enhancements in OVERRIDE_EVENT_OVP method of interface IF_FPM_OVP_CONF_EXIT which programmatically overriding UIBB visibility, as described in Hide the entire UIBB dynamically in standard OVP FPM using exit - and there are also no override, so this is not the cause ?

Sorry for being verbose but may be anyone have more ideas to check ?

The only one which I have left that there must be only one UIBB with relations for some reason, but I did not wanted to remove old one until new one will work properly, because I'm not sure what will happen if I will delete old one and if I will need to restore it - it might not display again as ATS version behaves.

hmm, interesting ... I am afraid, I have no idea what could cause that...

Kind regards,

Just for the sake of completeness of this thread:

Was able to resolve this issue simply by copying standard component configuration BS_BP_RELATIONS_ATS to customer namespace (with zero changes in configuration), and assigned it instead of standard, also updated wire respectively with new one - and then same UIBB finally appeared, along with old one.
