Hi all, Trinidad 1.2.11 is utterly broken (at least in this assumedly common setup) because it overwrites certain IDs by appending "j_id_1" to them. This breaks the PPR, which used to work impecably in Oracle ADF.
After more than 10 hours of investigation (!), by looking inside the Trinidad 1.2.11 source code and a lot of debugging and googling (where a similar issue is also reported, but unaddressed), I migrated to Trinidad 1.0.10, which works correctly on *exactly* the same setup, by not obliterating my IDs. So here is my setup (I will not paste my entire project, because it is irrelevant, I am sure this is very easily reproduced by performing a similar setup): 1.. Trinidad 1.2.11 over MyFaces-Core 1.2.6 2.. Jetty 6.1.15 3.. One JSPX page using JSP 2.0 4.. One TAGX tag file, using JSP 2.0, which includes by means of jsp:doBody some content from the JSPX page 5.. Four or five levels of tr:panelGroupLayout, which include some tr:inputText and tr:selectOneChoice components with given IDs 6.. partialTriggers between some of the tr:panelGroupLayout components, which reference the same IDs I explicitly set 7.. There are *no* subviews or any other naming containers outside the toplevel f:view Surprisingly, when the number of panelGroupLayout levels varies, the PPR stops working with a message complaining about "cannot find component by ID...". Because what Trinidad 1.2 actually does is when it thinks a certain component renders its children repeatedly, e.g. tr:forEach, it starts appending "j_id_1", "j_id_2" a.s.o. to the given child ID. Which makes sense for a tr:forEach and maybe for some f:facet components, but not for a tr:panelGroupLayout component. Looking at the Trinidad 1.2 source code it appears that it has some sort of algorithm for determining which component acts as a tr:forEach type of component, and if that is the case it starts appending the horrible "j_id_1" after any ID given to a child component. So basically if I set the partialTriggers to use the ID followed by "j_id_1" everything works fine. There is no telling when this ID clobbering takes place, but it may have something to do with nested tr:panelGroupLayout and/or the fact that I am using a TAGX tag file. I thought it was worth sharing this, since from my perspective it makes Trinindad 1.2 useless. I switched back to Trinidad 1.0 and everything works just fine. Quite disappointing though -- this should have been much better tested. Of course, I can provide any details if the Trinidad developers are interested in fixing this issue. Thanks, Nick
