Hello Alain<br><br>Thanks you for our kind suggestions.... so is // much more computationally intensive than using the full path in an XPath expression?<br><br>Regards<br><br>Peter<br>

<br>
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.<br>
<br>
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.<br>
<br>
There are many ways for optimizing and I would need a testcase or
a remote access to diagnose.<br>
<br>
Thank you for your feedbacks!<br>

<p>Dear List</p>
<p>I have a simple XForm using XMLSTForms rev 565 within eXist-db
version2.0. The form has a simple select1 control in it. The
control setting is selection="closed". </p>
<p>I am viewing the form on an IE9/Windows 7 machine. The IE9 is
in IE9 mode, not one of the other mode options.</p>
<p>When the control value is changed the dropdown with the various
options stays open for some seconds and during this time there
is significant processor activity as seen in the Task Manager.
I would have expected the new selection of an option in the
select1 box to have been instantaneous.</p>
<p>Any ideas on what is happening, and how I can improve this to
provide an instantaneous change to the selection of a new value?</p>
<p>Many thanks</p>
<p>Peter</p>
