WebCore bug or just the way it has always been

[dnickel]

I have only noticed this in the last few months and I don't remember it being this way.
Expressions used to evaluate correctly the first time a new var was introduced; pretty sure.
Lately they have not and I finally figured out what to do as it was driving me mmmmmmad.

If I create the var decRecRoomOffset and then make an expression to add it to RecRoomSetPoint it evalutes to 0. I had this same issue when trying to calculate azimuth values; I would always get wonky answers or 0 with simple math.
I stumbled upon the answer - when you create a var in define you have to Save the piston and re-edit and then do the expression.
Was this always this way?

Would need to see full logs during this editing (for the piston)

[dnickel]

Created test piston, edit and add variable.
Create a set variable expression.
At first it says invalid. I save the expression and re-edit and now it evaluates to 0.
Save the piston with the new var and re-edit and now it evaluates properly.
So it looks like new vars have to be saved first before the piston has access to them for evaluation.

@dnickel

Was this always this way?

I have observed this for some time (at least multiple months), because I remember stumbling on the save/re-edit trick. I cannot say for certain whether it was ever different (i.e. evaluate new variables on-the-fly).

[nh.schottfam]

If you want to try the latest webcore (if user install) to see if the changes I made helped.

[dnickel]

Will test, thanks!

[dnickel]

Using the Feb 15 build of WC and the Jan 15 build of WC Piston I get the same results.
Was WC Piston updated but the rev date not changed perhaps?
I did compile that as well and no change.
I "assume" you create a var list to use with Eval and without saving you cannot create a complete list; creating it dynamically is a pain?

any thing in logs

I may need a private note on steps...
