Hi,

I solved this problem by renaming a method in POJO.The problem was not a consistent one,it happens sometimes.

My earlier contents of 'Plan' class was like
public class Plan
{

private Plan currentPlan;
......
......

public Plan getCurrentPlan()
{
return currentPlan;
}

public void setCurrentPlan(Plan currentPlan)
{
this.currentPlan = currentPlan;
}

public boolean isCurrentPlan()
{
if(<...>)
{
return true;
}
else
{
return false;
}
}
}



Now i changed the isCurrentPlan() to isThisCurrentPlan() and now it works fine.


I think the method signature 'isCurrentPlan()' makes some problem when used by Java reflection inside Hibernate code.

When i debugged inside Hibernate source i found that sometimes the object Boolean is passed in the below mentioned line as Entity(??)...

org.hibernate.tuple.AbstractTuplizer.getIdentifier(AbstractTuplizer.java:103)

Anybody who knows this aspect please reply...


With thanks

Since both "get" and "is" are valid values of getting values from a JavaBean, Renaming the isCurrentPlan to isThisCurrentPlan seems to solve the problem. Im not sure if Class.getDeclaredMethods() is supposed to return the same set of methods in the *same* order, but if thats not the case, that answers your part about "issue happening sometimes".
