To confirm - issueing "libUrlResetAll" fixes the problem.
But what is the problem ??? I am loading thumbnails into my
application
asynchronously using the "load with message" command. As each
thumbnail
comes over I get the url from the cache and put the data into the
thumbnail
image finally unloading the url so as to clear the image from the
cache
memory. Seems all to work fine except that every so often with
loads of 100
images well the cache gets mucked up - here are the scripts:
setprop image_Loaded photoURL
put the long id of the target into thumbView
load url photoURL with message "image_DisplayLoaded"
end image_Loaded
on image_DisplayLoaded someURL, someStatus
put url someURL into someImage
set the image_Value of me to someImage
unload url someURL
end image_DisplayLoaded
setprop image_Value someImage
put the short id of the image_Object of me into imageObjectID
put someImage into image id imageObjectID of me
end image_Value
Perhaps I am not checking the status before unloading? Should not
cause this
problem but still... ?
I can't say for sure what the problem is, but you probably should
check the status at the beginning of the image_DisplayLoaded handler.
I see a possible problem if the load has failed for some reason, and
then you immediately do a "get url". In this case, the "get url" will
try to retrieve the data directly from the server, and may well fail
too as it's to the same url. Something like:
on image_DisplayLoaded someURL, someStatus
if someStatus is "cached" then
put url someURL into someImage
set the image_Value of me to someImage
unload url someURL
else
unload url someURL
## do some error handling here
## error message, etc.
end if
end image_DisplayLoaded
I'm not saying this is the problem, but it might be good to eliminate
this possibility first.
Cheers
Dave
