Hi all
I just came across a strange "feature". I'm not sure if I'm missing
something but think it could help others struggling with the same kind of problem.
My setup is the following:
- One EntityQuery
- One example object used in the query
- One method executing the query multiple times
In my method, I call the query with some different example objects and store the results
in different Lists to merge them in certain circumstances into one of them. The result was
not as expected: I had objects in my list I haven't copied into, so the question was:
"How did they come in my list?" After debugging the problem and it's
solution was clear: The EntityQuery method getResultList() works just with one single List
instance and therefore all resultLists were merged together. The solution was to
instantiate each time a new list and copy the ResultList into it.
From my point of view, the EntityQuery should return for each method
call a new List but I'm open for arguments against.
