Hello wilkinc,
It seems that Testleft does not support this method yet but since you've found the container of the child objects that you are looking for, you could implement something like this.
suppose you have your containter called myContainer.
Class_of_the_child myChildObject = null;
do{
try{
myChildObject = myContainer.Find<Class_of_the_child >(new YOUR_TECHNOLOGY_PATTERN()
{
my_search_criteria1 = search_criteria_param1,
my_search_criteria2 = search_criteria_param2
},50);
}catch{
//Do whatever error handling you wish. There is no need, the Find method returns null the the object is not found.
}
//Do whatever you want with the child. You may put them all into an array if you wish
while (myChildObject != null)
Best regards,
