We are having an intermittent problem with duplicate ids in our application. These are app generated id's eg; j_id123
We are using JSF1.2 (JSF-Facelets 1.1.14) and RichFaces 3.2.2.
We have seen it happen in dataTables, columns and an inplaceInput. The thing is it is intermittent and random - the same component can be fine for weeks then one day it throws an error. If you close the browser and open a new one the problem is gone!
Is this a known issue or is it something I am doing wrong?
I have also this problem.
It happens, when c:if and c:forEach are used.
The only solution I found is to assign unique ids by myself.
The best way is to avoid using JSTL tags, but it is not always possible.
