Invalid argument supplied for foreach() error on programmatic import of pageroutes

Scenario:
I am programmatically trying to import pagerouts as part of creating a 'mysite' module. I exported my pageroutes and saved them into files. I know that I will need to handle the list of roles at some point. For now, as I have an empty database, I know what my role numbers will be, so that is not an issue at this time.

The problem I have is that the first one is imported and created and the subsequent ones fail, but create unnamed/empty pageroutes.

Symptom:
warning: Invalid argument supplied for foreach() in /websites/{mysitename}/sites/all/modules/pageroute/pageroute_ui.forms.inc on line 493.

Diagnosis:
This error message is displayed because the variable 'route' on line 487 is not set.

Further debugging shows that the call order on the first import is to pageroute_ui_import_validate, then to
pageroute_ui_import_submit. The subsequent calls do not invoke pageroute_ui_import_validate and go directly to
pageroute_ui_import_submit. I've tried to debug further, but this is getting way involved and I have to meet
a deadline.

I have found a hack-around. If you test 'route' and it is FALSE, if you just invoke validate again, I can get
the imports to work. For now I will use that.

Sample code for how I invoke import:

function mymod_create_pageroutes($pageroute_file) {
	
	include_once('./'. drupal_get_path('module', 'pageroute') .'/pageroute.page_add.inc');
	include_once('./'. drupal_get_path('module', 'pageroute') .'/pageroute_ui.forms.inc');
	
	$form_id = 'pageroute_ui_import';
	$modulepath = drupal_get_path ('module', 'mymod');
	$pageroute_definition_file = $modulepath ."/pageroutes/" . $pageroute_file;

	$values = array();
	$values['import'] = file_get_contents($pageroute_definition_file);
	$values['op'] = 'Import';

	$form_state = array();
	$form_state['values'] = $values;
			
	drupal_execute($form_id,$form_state); 

}

Code for 'hack-around':

add after line 487 - $route = &$form_state['route'];

  // there is a problem that validate is not being called on multiple calls
  // when not validated, route is FALSE -- in that case force a validation
  if ($route == FALSE) {
    pageroute_ui_import_validate($form, &$form_state);
    $route = &$form_state['route'];
    if ($route == FALSE) {
      return FALSE;
    }
  }
