Cannot update ?

, ,
1

Dear all,

I’ve made a simple TJDOMObjectModel XQuery (see the below captured code)
but the result doesn’t contain Ino:ID which makes the update failed (error message below)


But there are 2 cases that the return result contains Ino:id (xmlObject.getId())
1.) if using TDOMObjectModel (not TJDOM)
2.) compile & run on another PC, using Java 1.4 (I can’t explain what’s the difference !!!)



is it a TaminoAPI4J.jar related issue ?


Any one has seen this kind of problem before ?
I read through the archives, just find that the XQuery return result is not guaranteed to have ino:id … is it still the case ?


Thanks everybody !


Regards,
Dee.

TResponse tamResponse = tacc.query (xQuery) ; // make the query
TXMLObject xmlObject = tamResponse.getXMLObjectIterator().next() ;

…

// modify xmlObject

tacc.update(xmlObject) ; // ← failed due to no ino:id ?!

By default xquery will not return the ino:id unless you formulate the xquery expression to do so. One possibility is to use the XQuery-Update feature to update individual element(s) and attribute(s). Take a look at FLWUExpr expressions in the XQuery section of the Tamino documentation.

Hope this helps.
