Stack Overflow Error - BeanFactory

Communities ColdBox HMVC
1

This message is part question and part sharing to help anyone else who
may encounter this.

I've spent more than a day fighting with a Stack Overflow error in a
new ColdBox - ColdFusion 9 Application. I am using the Auto-wire
dependency injection system native to ColdBox. I finally identified
the area of concern and have resolved issue; however, I am still not
exactly sure why this happened, and, have a little concern it could
pop up.

This is the code that directly caused the Stack Overflow Error.

Complete stab in the dark but have you tried moving the “varing” of language outside of the loop and just set inside the loop?

Thanks for the reply, John. I tried the following two methods based on
you response and both also had stack overflow errors.

var languages = [];
var lanuage = '';
var i = 0 ;
var n = arguments.qry.recordCount;
for (i=1; i<= n; i++) {

  language = dependency.BeanFactory.getModel('Language');
  
dependency.BeanFactory.populateFromQuery(target=language,qry=qry,rowNumber=i);
  arrayAppend(languages, dependency.BeanFactory.getModel('Language'));
}

/* AND */

var languages = [];
var lanuage = '';
var i = 0 ;
var n = arguments.qry.recordCount;
for (i=1; i<= n; i++) {
  arrayAppend(languages, dependency.BeanFactory.getModel('Language'));
  
dependency.BeanFactory.populateFromQuery(target=languages[i],qry=qry,rowNumber=i);
}

/* for those interested, here is the language object */

What’s the actual error?

Is it in ColdSpring, or in Coldbox?

Without knowing the loop that the StackOverflow is going through, I’m not sure what we can do to help.

Following, please find the full stack trace. The last CFC shifts between the InterceptorState and BeanFactory.

To clarify, I am using ColdBox’s DI solution exclusively. ColdSpring is not involved.

the stack shows the interceptors firing?

any more info here?

There is a Request.cfc Interceptor which reads a setting from the ColdBox Config and constructs any objects required to fullful a basic request (currently: Site, User). This issue is triggered by User.

Here are User’s dependencies:

property name=‘BeanFactory’ type=‘coldbox:plugin:BeanFactory’ setter=false getter=true;
property name=‘UserDAO’ type=‘model’ setter=false getter=true;
property name=‘i18nDAO’ type=‘model’ setter=false getter=true;
property name=‘RoleDAO’ type=‘model’ setter=false getter=true;

The user is first Constructed to be a ‘New User’ and then, if the proper conditions exist, the Request.cfc Interceptor will ask the User to self-populate. When I first had this issue. Here is the Populate() method within User.

/** Populate the User from the database. @property Define the criteria to use. Accepts ‘login’ and any valid User property. Example : ‘user_id’ or ‘email’. */ public boolean function populate (string property=‘User_ID’) { arguments.User = this; if (UserDAO.populate(argumentCollection=arguments)) variables.populated = true; else variables.populated = false; return variables.populated; }

And, here is a condensed version of UserDAO’s populate method:

SELECT XXXX

The populateUserLanguage() method is where I finally found a resolution. By rewriting the method as I previously posted, the error goes away. I also rewrote this behavior and placed the burden of creating/populating these language objects in a few other places and always received the same stack overflow error.

To further clarify, I’ve now tested by removing the BeanFactory from the creation of the new Object and still the error is caused.

// Create the Language
language = new shared.models.objects.Language();

// Old Method: language = dependency.BeanFactory.getModel(‘Language’);

// This line still causes the Stack Overflow.
dependency.BeanFactory.populateFromQuery(target=language,qry=qry,rowNumber=i);

I now have more information about this error. Seems, the bean is the
cause.

If the INIT method of the Language object has arguments defined, the
stack error occurs. If I remove the arguments from the constructor, it
works as expected.

I also defaulted every argument and still got the error. Here is the
BAD code... any thoughts?

/** @hint Represents a language. */
component name='Language' accessors=true autowire=false
  table='system_languages' cache=false singleton=false {

  property name='lid' ormtype='numeric' persistent=true;
  property name='language' ormtype='char' persistent=true;
  property name='language_short' ormtype='char' persistent=true;
  property name='language_medium' ormtype='char' persistent=true;
  property name='akamai_directory' ormtype='char' persistent=true;
  property name='iso_code' ormtype='char' persistent=true;
  property name='is_system_language' ormtype='boolean' persistent=true;

  /** Constructor. Languages should allways be populated during
construction or just after.
    The default language is 'ENGLISH' */
  public function init () {

    // Construct the language using arguments.
    setLID(arguments.lid);
    setLanguage(arguments.language);
    setLanguage_Short(arguments.Language_Short);
    setLanguage_Medium(arguments.Language_Medium);
    setAkamai_Directory(arguments.Akamai_Directory);
    setISO_Code(arguments.ISO_Code);
    setIs_System_Language(arguments.is_system_language);

    return this;
  }

  /** Facade Method for getIs_System_Langauge. Used to keep API
consistent. */
  public boolean function isSystemLanguage() {
    return getIs_System_Language();
  }
}

Is this a persistent CFC? I’m a bit confused as you have the table attribute, but not the persistent=“true” attribute.

/** @hint Represents a language. */
component name=‘Language’ accessors=true autowire=false

table=‘system_languages’ cache=false singleton=false {

11

Also, what where the constructor arguments?

Maybe you had a circular reference there the wiring was trying to detect.
