We are using v9.01FP7 and our XPages application works perfectly fine via browser, but when having to make changes designer is saying the 'com.ibm.xsp.extlib.relational.library' is missing. In fact when I goto Help and check the plug-ins I don't see this library installed; however, I have installed the 9.0.1 updateSiteOpenNTF-designer.zip plug-in which I can see includes 'com.ibm.xsp.extlib.relational_9.0.1v00_11_20141217-1000.jar.
It is my understanding that the 'com.ibm.xsp.extlib.relational.library' is part of the core ExtLib install for designer so I don't understand why this error would be occurring.
Do you have any issues locally?
Thanks,
Dwain Wuerfel
