Installation problem

[Sandor Vroemisse]

Hello,   We’ve just installed MMBase 1.7 and I wanted to play with the examples but they couldn’t be installed. Step 1 was completed with no errors (afa I remember). Yet, when I try to install any of the next steps it complains about missing builder files. Things like image.xml and url.xml, exactly those things one expects to be installed in step 1. Today, I can’t even go to /mmbase/mmexamples/install.jsp any more. It quits with an internal server error, saying:   java.lang.RuntimeException: The nodetype of node #4 could not be found (nodetype # -1)         at org.mmbase.module.core.MMObjectBuilder.getNode(MMObjectBuilder.java:1112) and so on.   What’s wrong?   TIA,   Sandor Vroemisse
