[chef] Re: Re: NoMethodError for LWRP within a ruby_block?

Thanks for the response. I forgot chef DSL isn't available within a 
ruby_block.
Basically, I'm trying to get my recipe actions executing in the right order,
using the chef tools as I understand them so far. I'll probably try 
run_context
today.

Given my cookbook, the run order I desire is:

1. Start mysql
2. Wait for innodb recovery to complete (i.e. wait for mysql to respond to 
queries).
3. Query a value from mysql
4. Take action on that value using my LWRP

But the run order that actually happened before I tried putting 3 and 4 into
a ruby_block was:

1. Query a value from mysql (got executed at compile phase)
2. Take action on that value using my LWRP (got executed at compile phase)
3. Start mysql (got executed at convergence phase)
4. Wait for innodb recovery to complete (i.e. wait for mysql to respond to 
queries). (got executed at convergence phase)


Items executing at compile phase rather than convergence phase is working
against me, I feel. I'll keep trying.

thx,
kallen
