RE: [FreeMarker-user] FW: crud screens and null.

[Vladimir O. <VO...@ci...>]

Well, that's the thing that it won't work:

${cellify(xxx)} will throw exception if 'xxx' is undefined. The only
feasible solution might have been ${cellify(xxx?default(''))}.
Readable?.. Not really. [#escape] directive helps here, but it's not
always that one can use it.

Isn't this what macros and functions are for?

${cellify(xxx)}

Create your own function and isn't it that easy?

And this is likely a candidate for a general library of functions as is
being discussed on a different thread.

Freemarker is already very powerful, it seems to me we should be careful
of proliferation of syntax and take advantage of its existing power.
