I am trying to make a custom build of dojo for my application in order
to speed it up a bit.
(See threads "[s2] Struts head tag KILLS (> 10s) page load time" and
"How to improve dojo performance in Struts 2.0.9")
I have followed the instructions for doing this are carefully as
possible from
http://cwiki.apache.org/S2WIKI/creating-a-custom-dojo-profile-for-struts-209.html.
My custom build appears to have worked. dojo.js is generated with the
struts widgets "Internalized", each page i load makes minimal requests
for other dojo scripts and the basic bind functionality of dojo works.
However the Struts:Combobox component used in my autocompleters does
not work. Some code is executed when i edit the field but it does not
result in a petition to the server y hence no autocomplete list is
shown. Dojo is configured in debug mode but gives no errors. The
struts folder containing the widgets is present in
<contextroot>/struts/dojo. Dojo correctly finds the dropdown image for
the input and uses the styles in ComboBox.css the only problem is that
it does not issue petitions to the server when the onKeyUp event fires.
I am using the 2.011 build of struts, is the process for building a
custom dojo build the same as in 2.09? I can't find any changes in the
ComboBox between these versions but is there anything else that might
be causing these problems.
Does anyone have any advice for how to start debugging this?
Thanks,
max
I'm not sure what is wrong, but the approach I'd take to debug it is:
- Use firebug to see if the page is getting a 404 trying to load any
of the resources required by dojo. This is the most likely cause if it
was working before you created the custom build
- Replace your dojo.js file with the dojo.js-uncompressed.js file also
created by the build process. This one contains comments and debug
info. See if any errors are now displayed
- Find the combobox code in dojo.js-uncompressed.js and use
breakpoints in firebug to find out exactly what's happening.
Let me know how you go.
