Hi Dave
I had a bit of trouble getting meta data working myself. This is the syntax
I ended up using. The key was using xmlRoot.
<cfset obj = Reactor.createRecord("customerProfile") />
<cfset nameMaxLen =
obj._getDictionary().getValue("xmlRoot.customerprofile.firstname.maxlength")
/>
>From my understanding you pay the hit of generating the XML in
_getDictionary() once, but after that its cached in the object.
As for validate. When I get some spare time ill try to blog how I do
validations. The best way I found on learning how to do it was to read the
code in Model-Glue for GenericCommmit events.
I spent some time myself trying to work out if I should use reactor or
transfer, but in the end the killer feature for me was this whole metadata
stuff and being able to get the maxlength from the database etc. without
having to code that into my config xml files. I understand in transfer you
have to create all this stuff yourself in the XML config.

Subject: [Reactor for CF] Accessing the metadata
Hi,
I can't seem to workout how to access the metadata for an object? What
I have is some textareas in a form that I need to know what the
maxlength is so I can do some jquery to limit the input.
I noticed in the project_dateMetadata.cfc is the variable that I need:
<cfset variables.metadata.fields[12]["length"] = "255" /> but how do I
access it from the record object or do I need to create a metadata
object on the project_data table? I have looked in abstractRecord and
I can see a _getObjectMetadata method, but will this give me the right
data and should I use it?
Also, does anyone have any links to an article/docs about using
validate().
One final thing, which I know is mentioned quite a lot, is Reactor
still being developed/complete/losing out to Transfer? Whenever, I
look at Transfer it seems overly complicated - maybe I just haven't
spent enough time reading about it, but I prefer Reactor and would
hate to see it fade away.
Cheers,
Dave
