"mytask13: execution of BeforeUpdatecaused by: System.NullPointerException: Attempt to de-reference a null object()"
I am trying update incident who hasn't assigned any template and attached to task.
Those incident who satisfy above condition I want their task's description to be updated and respected incident's template need to update.
Following is the code I am using :
trigger mytask13 on BMCServiceDesk__Task__c(after update,before update)
{
List<BMCServiceDesk__Incident__c> myinc{get;set;}
for(BMCServiceDesk__Task__c myobject :Trigger.new)
{
List<BMCServiceDesk__Task__c> mytask = [SELECT id,name,BMCServiceDesk__FKIncident__c FROM BMCServiceDesk__task__c where BMCServiceDesk__FKIncident__c !='' and BMCServiceDesk__FKIncident__r.BMCServiceDesk__FKTemplate__c = ''];
myobject.BMCServiceDesk__taskDescription__c = 'task description updated through trigger';
myobject.BMCServiceDesk__FKIncident__r.BMCServiceDesk__FKTemplate__c= 'a3k7F0000004UNvQAM';
}
}

BMCServiceDesk__FKIncident__c !='' : it gives us list of task who are attached to incident
and
BMCServiceDesk__FKIncident__r.BMCServiceDesk__FKTemplate__c = '' : it gives me list of incident who dosnt assigend any template.
As I need to check both the conditions I put them inside the query . i.e incident whose template field is blank and it is attached to an task as well.
