Undeclared identifier despite being imported

[mantielero]

I am getting the following error:
    
    
    occt.nim/src/wrapper/tkernel/ncollection/ncollection_types.nim(11, 92) 
Error: undeclared identifier: 'StandardTransient'
    
    
    Run

which refers to the following line within 
[ncollection-types.nim](https://github.com/mantielero/occt.nim/blob/3296bbd1ee276d7594cc7dbdb2ce4878208af853/src/wrapper/tkernel/ncollection/ncollection_types.nim#L11).

But I am importing the file `import tkernel/standard/standard_types` which 
defines 
[StandardTransient](https://github.com/mantielero/occt.nim/blob/3296bbd1ee276d7594cc7dbdb2ce4878208af853/src/wrapper/tkernel/standard/standard_types.nim#L9-L10).
 I am also using `*` to export it.

I am importing as follows:

>   * `src/occt.nim`
>     * `src/wrapper/occt_wrapper`
>       * `src/wrapper/tkernel`
>         * `src/wrapper/tkernel/standard/standard_types`
>         * `src/wrapper/tkernel/ncollection/ncollection_types`
>     -`src/wrapper/tkernel/standard/standard_types`
> 


Why am I getting the undeclared identifier? I bet I am not doing properly the 
imports but I don't know what
