Fixed Icicle request loading (and maybe broke something else)

[Jyrsa]

Hi,

The dynamic requesting in Icicle was broken and I fixed it so that it works for me (tm).

b07e564 was a straightforward carelessness error in refactoring and I fixed that.

b892441 broke stuff for me but I'm not 100% sure why. Might want to take a look at it.

The rest are just adding a simple dynamic example to Icicle.

If you want a peek of the changes in action, http://jyrsa.iki.fi/jyrsa/helmet/ is my entry to Apps4Finland (an open data contest in Finland).

Regards,
Jyrsa

Hi Thanks for your fixes! What do you mean with b892441 broke stuff for me but I'm not 100% sure why: do you mean that the commit fixed something that was triggering problems for you or that this specific commit breaks some examples ?

Thanks also for providing a test case! :)

b892441 removed a few lines that gave me errors. Apparently at some times this.config was null so evaluating this.config.constrained obviously led to an error.

All the examples seemed to work after removing those lines but I don't know if I missed something or if you have a grand plan or somesuch.
