Hi, Thanks for the contribution. Could you outline the scenario that causes an error which is fixed by this?

@michaelbromley this one of cases when we have on pagination called before data received. Hard to say exact cause it is in deps of ng-view navigation with bunch of pagination and requests . I'll check and try to get some details for you. also note that https://github.com/michaelbromley/angularUtils-pagination has same issue. Just updated to packed and had to patch same line

Update. Ok we have a call to reset current page numbers. this call may not be in correct point(ill try to work on it on my side ) but it leads to the point when there are 'new' that is awaiting for data, and old ones. we call

 if (paginationService.isRegistered(instance))
                            paginationService.setCurrentPage(instance, 1);

for all. and at that point they don't have currentPageParser initialized yet
