Associations and the Grails webflow
- by callie16
Hi, it's my first time using webflows in Grails and I can't seem to solve this.
I have 3 domain classes with associations that look something like this:
class A {
...
static hasMany = [ b : B ]
...
}
class B {
...
static belongsTo = [ a : A ]
static hasMany = [ c : C ]
...
}
class C {
...
static belongsTo = [ b : B ]
...
}
Now, the GSP communicates with the controller via Javascript (due to my use of Dojo). When I try to remoteFunction a normal action, I can do something like this:
def action1 = {
def anId = params.id
def currA = A.get(anId)
def sample = currA.b?.c // I can get all the way to 'c' without any problems
...
}
However, I have a webflow and the contents of that action is in the webflow... It looks something like this:
def someFlow = {
...
someState {
on("next") {
def anId = params.id // this does NOT return a null value
def currA = A.get(anId) // this does NOT return a null value
def sample = currA.b // error already occurs here and I need to get 'c'!
}.("somePage")
...
}
...
}
In this case, it tells me that b doesn't exist... so I can't even get to 'c'. Any suggestions on what to do???
Thanks... getting real desperate...
