problem with jqgrid data output

[eluser]maria clara[/eluser]
im having a problem with the output of my jqgrid..it only shows the header and within that the header names are the fields in the database..

Code:

str is null
anonymous(Object name=E)
anonymous(Object name=xml, div.ui-jqgrid-bdiv, Object name=rcnt value=0, Object name=more value=false, Object name=adjust value=0)
anonymous(XMLHttpRequest readyState=4 status=200 statusText=OK, "parsererror")
L()
anonymous(175)
[Break on this error] if (str.match("date")=="date")\r\nscript.js (line 1518)
E is null
[Break on this error] (function(){var l=this,g,y=l.jQuery,p=l....each(function(){o.dequeue(this,E)})}});\n

thanks in advance,
maria
