Control is FormControl, and i did’nt achieve to update the value.
I use this little hack : i instanciate a new FormControl with the new value <FormControl> ctrl = new FormControl('new value', Validators.required);
check @ecureuill ’ s comments… that worked for me. Though I am still solving other compilation errors, so havent tested yet for working of the set value yet.
that was an issue with imports and declaration variable in the app.module.ts. I solved it by removing some providers, imports and declaration that doesnt have to be there.
