More ESQL problems

Title: More ESQL problems





Sorry to bother everyone again, but I've got another problem with the ESQL logicsheet. Here's the code:


 esql:execute-query
 esql:queryselect ID from counters where link = 
 esql:parameter type=stringxsp:exprrequest.getParameter(file)
 /xsp:expr/esql:parameter/esql:query
 esql:results
 xsp:logic
 java.lang.String useragent;
 java.lang.String fileid;
 fileid = esql:get-string column=ID/;
 /xsp:logic


I'm trying to grab the ID column value and assign it to a Java string object for use in a further object; my site is littered with this methodology, and it usually works. However this code gives me the following error:

java.lang.Exception: XSP Java Compiler: Compilation failed for _download.java
373: Incompatible type for =. Can't convert org.w3c.dom.Node to java.lang.String.
 fileid = 
 ^
1 error

 at java.lang.Thread.run(Thread.java:498)


Instead of grabbing the value of the column as a string, it looks like the ESQL sheet is grabbing a Node object. The code that's generated by Cocoon is:

 java.lang.String fileid;


 fileid = xspParentNode = xspCurrentNode;
 xspNodeStack.push(xspParentNode);
 xspCurrentNode = document.createElement(esql:get-string);
 xspParentNode.appendChild(xspCurrentNode);


Anyone know why the ESQL taglib is so confused? Thanks!

Yes, it's a reply 
to my own post. Found the problem. I moved the xsp:logic 
tags to inside a esql:row-results like so:
 
esql:row-results 
xsp:logic 
java.lang.String 
useragent; 
java.lang.String fileid;

 
fileid = esql:get-string 
column="ID"/; 
/xsp:logic 
/esql:row-resultsAnd it worked just 
fine.
