Current behavior

When property names are with dot notation like from an elastic search :
"body.property.subproperty" the deep-getter fails to retrieve the value of the cell
Expected behavior

Deep-getter should have a check if obj[path] returns a value and if no then it can proceed in destructuring the path.
Reproduction of the problem
Provide an object with keys names in following format:
"main.property"
"main.property.subproperty"

What is the motivation / use case for changing the behavior?

when using the datatable with serverside Java elastic search

If you do [prop]="'foo.bar.cat'" does it work? Can you provide a demo?

[TINITUS]

I am using columns array to set up columns as I need to provide those fromthe outside in order to create a generic grid list. That's why I haven't tested with template way of setting in columns.
I will try to provide demo by the end of today.
Here is a simple demo: http://embed.plnkr.co/XzyW4uZ1Kiz8BIN61h74/

Just FYI #494 changes valueGetter code a bit and renames deep-getter.ts to column-prop-getters.ts
So if #494 is merged when someone works on this, look for that file instead.

[TINITUS]

Sure, Arlowhite, I saw your PR but tnx for the notice.

[arlowhite]

My PR was just merged. :)
So fixing this is just a few lines of code in column-prop-getters.ts

I will create a PR to fix this soon unless someone else says they're already working on it.

@arlowhite - did you have a chance to make this PR yet?
