Here is the query I put in task.hbm.xml :
<query name="tasksProjects">From Task where idProject in (?)</query>
Here is the fill call :
for (i = 0; i < projectsArray.length; i++)
{
mx.controls.Alert.show(projectsArray.getItemAt(i).id);
}
taskDataService.fill(tasksArray, "tasksProjects", [*]);
But what i have to put to replace *. I tried "project1, project2"...
It doesn't work.
