In Om, why does transact not update cursor value.

[John Chijioke]

When a transact has happened to cursor successfully. Why does (om/value cursor) not return the current value in (om/state cursor) at (om/path cursor)?

om/value is the cached value that was seen at the start of render which is useful to know. You need to deref if you absolutely need to see what the current value is.

Hi David,

Then the name should be more like om/cached-value or om/init-value. It's very misleading as om/value. And I suggest there should be a name for getting the current value as having to do (get-in @(om/state cursor)‎ (om/path cursor) ) is very boring. 

Moreover, I still have not found a great need for om/value as it's currently implemented.

WDYT?

John.

Try @cursor ?

Thanks a lot for that pointer. I really appreciate.

I also didn't understand that was what David meant by "you absolutely need to deref".

In some life-cycle methods you need to deref and others you don't. I found it confusing until I got that straight.
