Re: [Xsltforms-support] Select1 box: What is the reason for the delay?

[Alain C. <ala...@ag...>]

Hello Peter,

There is no specific reason for a select1 control to be slow. Probably, 
there is a refresh just after selecting one item and the size/structure 
of the corresponding instance might be the cause of this. The involved 
XPath expressions might also require a lot of time, for example if the 
// operator is used.

You can use the XSLTForms Profiler (pressing F1 to be in the Debug Mode) 
and the native IE Script Profiler to locate functions/methods with heavy 
execution times.

There are many ways for optimizing and I would need a testcase or a 
remote access to diagnose.

Thank you for your feedbacks!
