Weird Scope Issue

[jarofclay]

Cfmongodb is awesome.  It's working well in Wirebox as well.  We have this weird issue though when calling functions in a CFC that behaves differently than on a CFM page.  

Example (works in CFM):

coll  = mongoService.getDBCollection( "announcements" );

announcements =coll.query().$gt("expiredate", dateconvert("local2utc",now())).find( limit=1, sort={"ts"=-1} );

The same code above when in a CFC (assume mongoService is a injected configured mongo instance) doesn't work and it will throw an error:

coll is undefined.

This is where it gets really weird. If we do this.. it works. 

coll  = mongoService.getDBCollection( "announcements" );

coll; // or just a writedump(coll);

announcements =coll.query().$gt("expiredate", dateconvert("local2utc",now())).find( limit=1, sort={"ts"=-1} );

Scratches head.   We have tried this 20 different ways to Sunday (w/o Wirebox, instantiate from the function) and it behaves the same.  So Wirebox doesn't affect the result.  Any ideas on why this variable needs a touch? Is it lonely?? :)

where are you executing the code in the cfc, i'm assuming its in a function?

so really you should scope the variables

have you tried

var coll = mongoService.getDBCollection( "announcements" );

var announcements = coll.query().$gt("expiredate", dateconvert("local2utc",now())).find( limit=1, sort={"ts"=-1} );

Hey Joe,

I confess, this is quite strange. First, what version of CF are you on? Have you tried restarting CF?

Now, some standard debugging:

What is "mongoService"?

What is different about it when it's used in your .cfm page vs. your component? Is it initialized differently? 

If you do this:

var coll = mongoService.getDBCollection( "announcements" );

coll.getMongoDBCollection();

does it error?

What if you do a simpler query: coll.findById(...);

All most likely shots in the dark but we need to start somewhere.

And +1 to what Chris said: always var scope. Always. 

Though I don't think that's your issue here.
