Hi all,
The fileupload component in the incubator has a wonky
non-OpenLaszlo-like API for listening for responses. In OpenLaszlo, when
you're working with a class that makes HTTP (or other asynchronous
activities), you do:
<dataset name="myData" src="http:path/to/data.jsp">
<handler name="ondata">
// Now you know the response has arrived.
</handler>
</dataset>
This approach provides lots of flexibility - you can use delegates to
listen for the event if necessary, and handlers can be anywhere.
However, the fileupload component requires the developer to override a
method. e.g.
<fileupload>
<method name="onComplete">
// Now you know your file has been uploaded.
</method>
</fileupload>
This isn't laszlo-y at all.
I recently filed LPP-8729 against the fileupload component to represent
this problem. I'm volunteering to fix this, but it would involve a
change to the API of fileupload.
**THE CHANGE**
Instead of writing:
<fileupload>
<method name="onComplete">
// Now you know your file has been uploaded.
</method>
</fileupload>
... you would write:
<fileupload>
<handler name="onComplete">
// Now you know your file has been uploaded.
</handler>
</fileupload>
Since the method names unfortunately begin with "on", the two approaches
couldn't run concurrently. It would have to be an overnight change.
Does anyone object to this?
