Problem in eclipse: java.lang.ClassCastException

Question

It was two days that I constantly get an error dialog every 45 seconds with the name:

There were some problems

and it says:

java.lang.ClassCastException

and in detail there is a repeating line that says:

org.eclipse.core.internal.dtree.NoDataDeltaNode cannot be passed to org.eclipse.core.internal.dtree.DataTreeNode

here is his picture:

I click OK and continue coding, my code works fine, both in the simulator and on my mobile device, but I’m really annoyed to see this dialog box every minute, or mine even less than a minute!

Answer 1

Your workplace may be damaged in some way. Try setting up a new workspace.

Choose File → Switch Workspace → Other in the eclipse menu. Then select a new directory. You will have to re-import your sources and make all the configurations.
