Something like …use getLatte()->invokeFilter() is better, isn't?

[fprochazka]

Is it?

[dg]

What is „use your filter directly“?

[fprochazka]

Filters are usualy shortcuts for existing functions/methods. If this is deprecated, spaghetti like getLatte()->invokeFilter() is definitely a no-go and it's better to directly use that function/method, that the filter is an alias for.

[dg]

But it is lie, it is not deprecated, i.e. invokeFilter is not deprecated.

[fprochazka]

I believe using the filter directly is better than spaghetti. If you don't like the formulation, write here how you want it and I will change it.

You said „I know it's not a best practise, but often I would use the template object helpers in presenter or control.“ :-)

I belive that E_DEPRECATED message should explaind, how to quickly fix it.
