Out of Memory Error

[br8kpoint]

I have a model that I cannot list through the all method. I can access
the index page if there are no models that exist but when even one
model exists I get an Java::JavaLang::OutOfMemoryError (Java heap
space): I have traced this down into the execution of the _all rule
that neo4jrb sets up but I don't know enough to trace it further.
Below is the console output and the model definition. Any help would
be greatly appreciated.

How big is the result you are expecting? Might be that there is a large collection being populated?

Hi

How can I reproduce this error ?
What does the controller code look like ?
Are you trying to get all the PageTemplate in the controller action ?
If you are, how many PageTemplate nodes are there ?

Cheers
Andreas

Problem solved. Turned out to be an inadvertent recursion issue.
Thanks.
