This thread is intended as a list of known issues with OpenMx 2.0 while it is in beta.
There are two known issues with the first beta, as of its public launch on 5/30/14:
mxOption()function can be used to switch to using NPSOL if necessary. Nonetheless, we encourage those who are beta-testing version 2.0 to use CSOLNP as much as possible because it's a new feature.
Also, a word of advice: users should definitely get into the habit of ALWAYS using
$ instead of
@. For example,
myModelRun@output$estimate would now be
myModelRun$output$estimate. We CANNOT guarantee that every usage of the
@ accessor that worked with versions 1.3/1.4 will continue to work in 2.0.
