I'm diving further into JSUI and upon revisiting it I realize how it's more or less like Processing which makes sense from a technical perspective.

With that said I am getting what may be inconsistent results with the methods glpushmatrix() and glpopmatrix(). I am basing this off of my my understanding of the similar methods in Processing and my reading on the topic.

When I initially render the JSUI object, a rectangle is rotate/transformed but the circle is not. 

When I send a bang to the object in order to re-render it, all shapes are transformed. 

This suggests that it's no longer obeying the glpushmatrix().

Any thoughts and insight into this? Thanks.

please attach a script and patch and I'll take a look.

I did some more testing to pinpoint the issue and it may be related to shapeorient(). I will share that when I get a chance soon.

Thanks @Rob Ramirez

So I removed the shapeorient() method because I believe I was misusing it. However, I am curious about how the glpushmatrix and pop methods should work. To my understanding, they create different matrices that allows for different visual attributes. I attempted to create a matrix with a blue square and another separate matrix that should ignore the blue glcolor but it does not.

Those methods only work on projection matrices (orthographic/2d or perspective/3d), not on generic styles.
