I have a piece of method code that runs a get with criteria. Immediately after running the get the code checks the isError property and if true then returns the error. In a particular use case, the get does not return any results. I have found that no results leads to isError being true on the result after the apply. I have never noticed this before. Is this normal behavior? Here is a code snippet.
Item affectedItemsAllGens;
affectedItemsAllGens = this.newItem("Change Controlled Item","get"); affectedItemsAllGens.setAttribute("select","config_id,keyed_name,generation,state,itemtype"); affectedItemsAllGens.setAttribute("order_by","config_id,generation"); affectedItemsAllGens.setProperty("generation","*"); affectedItemsAllGens.setPropertyCondition("generation","like"); affectedItemsAllGens.setProperty("config_id",configList.ToString()); affectedItemsAllGens.setPropertyCondition("config_id","in");
affectedItemsAllGens.setProperty("state", "'Development','Engineering Ready','Validation','Validation Change Pending','Deployment','Deployment Change Pending'");
affectedItemsAllGens.setPropertyCondition("state", "in");
affectedItemsAllGens = affectedItemsAllGens.apply();
//isError is true when apply does not return results. The getErrorString value is "No items of type Change Controlled Item found."
if (affectedItemsAllGens.isError())
{ return inn.newError("There was an error returning all generations of the affected items.<br>" + affectedItemsAllGens.getErrorDetail()); }
I don't want to return an error because the get did not return results. What are some options for catching a real error versus when the get does not return results?

Hi Dennis,
You can test "affectedItemsAllGens.isEmpty()". This will return true when nothing has been found but the AML was still valid. Or you can check getItemCount(). It will be 0 for a "get" that returned no results or -1 for a "get" that returned an error due to some legitimate reason.
Hope this helps,
Brian.

{
return inn.newError("Error:<br><br>" + affectedItemsAllGens.getErrorDetail());
}
// "No Items found" case
else if(affectedItemsAllGens.isError())
{
return inn.newResult(affectedItemsAllGens.getErrorDetail());
}
