I created a calendar control webpart which has custom properties .Depending on
what user enters in custom properties the view of calendar control is changed

Now i again place one more webpart on same page .so there will be 2 webparts of
same type .One webpart is getting data from one list .
now the issue is if i make changes in second webpart custom properties it also
changes the custom properties of first webpart
why is this happening
What is the work around for this so that they both remain independent.
