Hi all, I am a newbie in Alfresco, I couldn't find any info about my issue looking into the forum, so I am here 
My isssue: I want to assign value from content metadata property (attached to workflow proces) to variable that is presented in the forms (Web CLient Alfresco).
I wanna do two things:
1)assign content property "sgn:Nazwa" to my task variable "ct_nazwa" and be able to display it on my web form.
2) update (after some user changes in UI in a step przegladTask) content property "sgn:Nazwa" from task variable ct_nazwa
My workflow model:

thanks for Your answer, You've helped me to go few steps further
Your exact snippet didn't work, but it had inspired me to search in a different way and helped me to find out that:
when I set web-client-config just as You set, and when I try this:
it almost works, I mean: I can get a value from a field from content, then I can display it in a UI, then I can change it on UI and save it to bpm_package.children[0].properties["sgn:Nazwa"] during first step and finally I can display that value in second step. There is only one thing i do not understand: When i navigate on my task (the second step) UI to Resources->Actions->Edit Content Properties I still see the old value. So it seems that I have already changed only on some kind of a copy of a metadata. How to make update on original content metadata ?
