ResourceMulitParentClassLoader NWDS 7.3

Hi Everybody

I found exception when connecting menu in our site .

I Think the menu is linked two program sources ... Actually I don't know ..

Give me a hands.

The initial exception that caused the request to fail, was:

java.lang.ClassCastException: class com.sapportals.portal.pcd.gl.PcdGlDeltaLink:service:com.sap.tc.pcd.gl.srv@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@63012b1b@alive incompatible with interface com.sap.portal.pcm.admin.IAttributeSet:library:tc~epbc~pcm~adminapi@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@22c296dd@alive
