DJP1S Expression cannot be assigned
I'm trying to assign the date of a project parent object to the maximum date due of related child tasks.
I'm getting a "Save error: Expression cannot be assigned" error message based on the second variable setNewDueDate()
P1Task__c maxTaskDate = [SELECT Due__c
FROM Page1Task__c
WHERE Project__c = :this.currentTask.Project__c
AND Status__c != '6) Completed'
AND Status__c != '5) Deferred'
AND Seq__c > :this.currentTask.Seq__c
AND Due_Date_Auto_Calc__c = 'Always'
AND Lag_Days__c != null
ORDER BY Seq__c DESC
LIMIT 1];
public void setNewDueDate(){
if(P1Project__c.Due__c != maxTaskDate.Due__c){
P1Project__c.Due__c = maxTaskDate.Due__c;
}
}
Now, I've tried this as well and it doesn't like it either.
Here's what I ended up doing. This seems to do the trick.
public void setNewDueDate(){ P1Task__c maxTaskDate = [SELECT Due__c FROM P1Task__c WHERE Project__c = :this.currentTask.Project__c AND Status__c != '6) Completed' AND Status__c != '5) Deferred' AND Due_Date_Auto_Calc__c = 'Always' AND Lag_Days__c != null ORDER BY Seq__c DESC LIMIT 1]; P1Project__c project = [SELECT Due__c FROM P1Project__c WHERE ID = :this.currentTask.Project__c]; if(project.Due__c != maxTaskDate.Due__c){ project.Due__c = maxTaskDate.Due__c; update project; } }All Answers
Hi
try this
public void setNewDueDate(){ if(P1Project__c.Due__c != maxTaskDate.Due__c){ P1Project__c.Due__c = maxTaskDate[0].Due__c; } }Thanks, I thought that would hti the nail on the head, but I'm now getting the following error:
Can you post littile more code snippet,so that analyze the what you declaring and what you are assigning
public void setNewDueDate(){ if(P1Project__c.Due__c != maxTaskDate.get(0).Due__c){ P1Project__c.Due__c = maxTaskDate.get(0).Due__c; } }Above will solve your issue . Please mark this as solved if this solves your issueHere's what I ended up doing. This seems to do the trick.
public void setNewDueDate(){ P1Task__c maxTaskDate = [SELECT Due__c FROM P1Task__c WHERE Project__c = :this.currentTask.Project__c AND Status__c != '6) Completed' AND Status__c != '5) Deferred' AND Due_Date_Auto_Calc__c = 'Always' AND Lag_Days__c != null ORDER BY Seq__c DESC LIMIT 1]; P1Project__c project = [SELECT Due__c FROM P1Project__c WHERE ID = :this.currentTask.Project__c]; if(project.Due__c != maxTaskDate.Due__c){ project.Due__c = maxTaskDate.Due__c; update project; } }
