I have a jsp that use <db:file> for DISKBLOB uploads, but if the user modify
the path string after selecting the file the folowing exception occurs :
2002-11-18 11:20:21 StandardWrapperValve[dbformscontrol]: Servlet.service()
for servlet dbformscontrol threw exception
java.lang.NegativeArraySizeException
 at org.dbforms.util.FileHolder.bufferInMemory(FileHolder.java:119)
 at org.dbforms.util.FileHolder.<init>(FileHolder.java:70)
 at org.dbforms.util.MultipartRequest.<init>(MultipartRequest.java:145)
 at org.dbforms.Controller.process(Controller.java:129)
 at org.dbforms.Controller.doPost(Controller.java:108)
 at javax.servlet.http.HttpServlet.service(HttpServlet.java:760)
 at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
.........

I would like to know how to catch/prevent this exception with DBForms
because it seems that thi occurs before the preinsert method invocation.
Thanks a lot for your suggestions.
