Seva,
First Test: server.py and index.py in same directory, index.html in
public sub-directory. No images in public.
python server.py from a cmd window. python index.py from a separate cmd
window
Server output:
Deborah - - [26/Apr/2012 14:42:20] "GET /public/index.html HTTP/1.1" 200 -
Deborah - - [26/Apr/2012 14:42:20] code 404, message File not found
Deborah - - [26/Apr/2012 14:42:20] "GET /public/tree-closed.gif
HTTP/1.1" 404 -
The application displays as it should with tree-closed images and the
the branches can be opened and then display tree-open images.
Second Test: exactly as first test except the images are copied into the
public sub-directory.
Server Output:
Deborah - - [26/Apr/2012 14:57:01] "GET /public/index.html HTTP/1.1" 200 -
Deborah - - [26/Apr/2012 14:57:01] "GET /public/tree-closed.gif
HTTP/1.1" 200 -
The application behaves as expected, exactly like the first test.
I took note of your remark about TreeItem.imgSrc possibly being called
without a Tree object and traced the calls back to
TreeItem.updateState(). In the else: clause in that method imgSrc is
called twice for tree_closed.gif without a Tree object (presumably, once
for each branch. It seemed to me that these calls were probably
unnecessary and also likely to fail, so I inserted a test for the tree
object and continued only if the object existed. Somewhere around line
331 of TreeItem.py.
if self.tree:
DOM.setAttribute(self.imgElem, "src",
self.imgSrc("tree_closed.gif"))
Third Test: exactly as first test except imgSrc not called on
tree_closed.gif if not self.tree
Server Output:
Deborah - - [26/Apr/2012 5:11:10] "GET /public/index.html HTTP/1.1" 200 -
No HTTP for images! The application again behaves as it should.
Conclusion: The HTTP GETs for the images are caused by calling
TreeItem.imgSrc without a Tree object and are unnecessary. Probably
TreeItem.updateState() should test for valid Tree object in all its
branches because different initial tree structures might hit different
branches before the Tree is constructed.
It would be very interesting to hear whether doing that modification to
TreeItem.updateState() will fix the problem for you too.
