Why don't you use tacos:ProgressBar. It is easy to use.

The XTile seems to work exactly how I want it to, but there is a problem.

This is my setup:

Stage 1:
- User selects file in upload component and submits form.

I needed a way to keep track of the progress of the file while it was 
uploading (to implement a progress bar). I couldn't do this in the same 
listener as the one that is called when the form is submitted because 
async submits don't work with upload components (apparently). So it was 
suggested to me that I create a thread that will be initialized when the 
form is submitted and it will handle the file uploading.


- Thread is initialized with filename and inputstream and starts running.
- Thread is stored in a static Map of threads with its hashCode as the key

The listener finishes and the page reloads.

Stage 2:
- XTile calls a listener to start watching the progress of the file in the 
thread.


The send function for XTile passes in the hashCode of the thread that was 
used to upload the file (stored in a hidden field on the page).


The method is called until I put in the call to get my thread from the 
static Map. I get this error in the firebug console:


  response.responseXML has no properties.



Any ideas how to fix this? Or a better way of handling tracking the 
progress of a file?

I don't think this would work in this case. The @InvokeListener component 
is

called on the server side, before the rendered response is flushed to the
client. What is discussed here is having a listener invoked after the page
is rendered on the client side, typically for a wait screen that will keep
displaying an animated gif until a long database transaction completes on
the server side (at least that is why I needed this).

 called _after_ any point where we could insert any custom js.

 The workaround I found to work perfectly is use contrib:XTile

 instead, with a small js script that calls the XTile generated js

Re: Call listener after page appears on screen

2006-10-27 Thread Christian Dutaret 

On some pages with a lot of EventListeners, I also see this 
tapestry.cleanConnect is not a function every now and then. When this
occurs, all the ajax stuff on the page won't work, since the connect events
are never executed. The problem only shows with Firefox, never with IE.
After I disabled Firebug, the problem never showed up again. I guess that
Firebug sometimes fails to execute some dojo.require stuff on highly
js-loaded pages.

Since most of the visitors of my website won't use Firebug, this shouldn't
be too much of an issue ;-)

2006/10/26, Peter Beshai [EMAIL PROTECTED]:


I did eventually try that and it worked but it seemed slightly volatile.
I'm
not sure if this has to do with how my snapshots have been rolled back to
August versions (see snapshots thread), but I randomly see in my dojo
console tapestry.cleanConnect is not a function and when that happens
that
solution doesn't work.

Re: Call listener after page appears on screen

2006-10-27 Thread Peter Beshai 
I had tried, but it seemed like tacos wouldn't work with Tapestry 4.1.1. I 
kept getting errors about things in hivemind being duplicated and it was 
just giving me a headache. So I'm going to create a wrapper for the new dojo 
progress bar, which should do the trick :-)

I don't think this would work in this case. The @InvokeListener component is
called on the server side, before the rendered response is flushed to the
client. What is discussed here is having a listener invoked after the page
is rendered on the client side, typically for a wait screen that will keep
displaying an animated gif until a long database transaction completes on
the server side (at least that is why I needed this).

Re: Call listener after page appears on screen

2006-10-26 Thread Peter Beshai 

The XTile seems to work exactly how I want it to, but there is a problem.

This is my setup:

Stage 1:
- User selects file in upload component and submits form.

I needed a way to keep track of the progress of the file while it was 
uploading (to implement a progress bar). I couldn't do this in the same 
listener as the one that is called when the form is submitted because async 
submits don't work with upload components (apparently). So it was suggested 
to me that I create a thread that will be initialized when the form is 
submitted and it will handle the file uploading.


- Thread is initialized with filename and inputstream and starts running.
- Thread is stored in a static Map of threads with its hashCode as the key

The listener finishes and the page reloads.

Stage 2:
- XTile calls a listener to start watching the progress of the file in the 
thread.


The send function for XTile passes in the hashCode of the thread that was 
used to upload the file (stored in a hidden field on the page).


The method is called until I put in the call to get my thread from the 
static Map. I get this error in the firebug console:


  response.responseXML has no properties.



Any ideas how to fix this? Or a better way of handling tracking the progress 
of a file?

I don't think this would work in this case. The @InvokeListener component 
is

called on the server side, before the rendered response is flushed to the
client. What is discussed here is having a listener invoked after the page
is rendered on the client side, typically for a wait screen that will keep
displaying an animated gif until a long database transaction completes on
the server side (at least that is why I needed this).

Why not just use an @InvokeListener component as the last component in
your page?

 As you mentioned, this is probably due to tapestry connect events being
 called _after_ any point where we could insert any custom js.

 The workaround I found to work perfectly is use contrib:XTile component
 instead, with a small js script that calls the XTile generated js
function
 at the bottom of the page

Re: Call listener after page appears on screen

Ok, resolved the response.responseXML has no properties problem. I was 
tipped off by this post:

public void xTileListener(IRequestCycle cycle, String stringKey) {

instead of Integer threadKey as the parameter.

Thanks for the help!

I did eventually try that and it worked but it seemed slightly volatile. I'm 
not sure if this has to do with how my snapshots have been rolled back to 
August versions (see snapshots thread), but I randomly see in my dojo 
console tapestry.cleanConnect is not a function and when that happens that 
solution doesn't work.
