Unable to pass argument to nested function defined as argument

[dariomangoni@…]

I have an outer function that have:

• a Real argument
• a function

Passing the real argument to the function results in:

Function parameter inVal was not given by the function call, and does not have a default value.

I'm on OpenModelica v1.16.0-dev-275-g033f38916

minimal example

[dariomangoni@…]

P.S. it suffices to declare
myInnerFun=FunctionPass3.Functions.InnerFun()
to
myInnerFun=FunctionPass3.Functions.InnerFun
to make it work.

In Dymola no warning were thrown so I cannot say if it is a bug or not.

To be honest, I never fully understood the semantics of parameters in functions

@perost, any comment on this case?

[Per Östlund]

FunctionPass3.Functions.InnerFun() is a function call, which fails due to the reason given in the error message. FunctionPass3.Functions.InnerFun on the other hand is a function reference, so no argument is needed and indeed not expected. So from what I can see this is working as intended.

[dariomangoni@…]

Can I have another opportunity here? :-)
My previous example was too minimal. The real issue is when the function argument is binded, that is not what I posted initially.

The very same error happens when I bind an argument to InnerFun like this
myInnerFun=FunctionPass3.Functions.InnerFun(k=1)
Previously the function argument was passed without any binding and it was working, but that is not what I wanted.

new example

Replying to dariomangoni@…:

The very same error happens when I bind an argument to InnerFun like this
myInnerFun=FunctionPass3.Functions.InnerFun(k=1)

Because that's still a function call and not a modification. If you want to modify myInnerFun I guess you need to redeclare it.
