[Laszlo-dev] Rest Support

[Henry Minsky]

Using the .jsp code from Andre to induce a 401 error, I am getting the
onerror event and error string properly


LzLoadQueue.XMLOnDataHandler success <?xml version="1.0"
encoding="UTF-8"?><!DOCTYPE laszlo-data><resultset><error status="2"
msg="data source error for http://127.0.0.1:8080/trunk/test/post2/foo.jsp:
HTTP Status code: 401:Unauthorized"/></resultset>
 «LoadObj#0| err.lzx (loading)» «LzLoader#1| err.lzx (loading)»
ERROR: data source error for http://127.0.0.1:8080/trunk/test/post2/foo.jsp:
HTTP Status code: 401:Unauthorized
onerror data source error for http://127.0.0.1:8080/trunk/test/post2/foo.jsp:
HTTP Status code: 401:Unauthorized
lzx> mydata.getErrorString()
'data source error for http://127.0.0.1:8080/trunk/test/post2/foo.jsp: HTTP
Status code: 401:Unauthorized'
lzx>

Are you sure you are actually being sent a 401 error from your back-end
server?
