[flexcoders] Re: Browser Memory Consumption not coming down even after remove child

2009-02-19 Thread Nirav Gosalia
I faced the problem in Flash Player 9 as well.

I think the issue is that the garbage collection of non referenced 
entities is not happening due to which my browser memory footprint 
goes on icreasing making the app very sluggish and eventually hang.

When I say 'hang' I mean popups stop opening, traversing among fields 
in a form using the tab key does not work etc.

Also the fact that those non referenced objects get GC'd using the 
Run Garbage Collector button in flex profiler shows that my code does 
not have any other reference to those objects !

Can you suggest me the approach that I should follow as I dont know 
What Next ?

[flexcoders] Browser Memory Consumption not coming down even after remove child

2009-02-19 Thread Nirav Gosalia
Hi,

We have developed large applications like CRM typically having 
several tabs.

We allow the user to travere a list of names in a tree and on his 
choice we add tabs to the tab navigator. These tabs can be closed by 
the user using a close button on the tab.

Issue: As the user opens new tabs the browser consumes more and more 
memory(> 250MB). When tabs are closed we explicitly use removeChildAt
() method to remove them from the tab navigator. However browser 
memory consumption does not decrease.

In Flex profiler the closed tabs get garbage collected when I click 
on the 'Run Garbage Collector' button which proves that there are no 
references to the closed tabs and they are perfect candidates for GC.

Why does the browser memory consumption not go down ? 
The application gets sluggish and eventually hangs ? 

We are not in a position to do a production release till we get 
around this issue ?

I am using IE7 and flash player 10

Please help !





[flexcoders] Flex Application Memory Footprint

2008-11-06 Thread Nirav Gosalia
Hi,

 

We are developing a CRM application using Flex.

 

The SWF size is 1.5 MB. The application has around 15 tabs. When all the
tabs are visited once the application shows a memory foot print of 400 MB in
the windows task manager.

I used flex profiler but there is no memory leak. I was wondering that how
flex handles garbage collection because once the tabs are created they never
seem to be releasing any memory.

 

Also flex profiler shows that my Datagrid header renderer occupies 40% of
the total memory consumed. 

 

Can someone suggest ways of reducing the memory foot print and show an ideal
way of writing a header renderer (we use it for full database sort).

 

Regards,

Nirav Gosalia



[flexcoders] SWF size

2008-09-09 Thread Gosalia, Nirav
Hi,

 

We are planning to build a CRM application using Flex as the front end. 

 

The scope of the application has been defined and the flex prototype
application made by our developers is exceeding 1 MB in size. 

What can be done to reduce the size of the application SWF ?

 

Is it a good idea to make (heavy) enterprise applications like a CRM or
ERP in Flex?

Nirav Gosalia

[flexcoders] Issue with the datagrid refresh

2008-05-28 Thread Gosalia, Nirav
Hi Guys,
 
I have a data grid with a customize button that can let the user select
the columns that he wants to view. 
I change the visible property of the columns according to the user
preference and save this information in a shared object on the client
machine.
 
On startup the data grid picks up the columns visibility information
from the shared object and initializes. Every thing works fine till now.
 
The data grid is binded with an arraycollection. When the data in the
arraycollection changes then I see that all the columns in the grid
become visible which is not expected.
Now the magic --> the moment I resize any column the unwanted columns
disappear and I see the columns that the user wanted to see.
 
Can some one help me on this ?

[flexcoders] F2B2 + FDS - Didn't recieve an acknowledge message

2006-05-23 Thread Nirav Mehta



Hi,

We are integrating Flex Beta 2 with FDS, and are getting a "Didn't 
recieve an acknowledge message" error. Couldn't figure out what's the 
cause. Could somebody help?

Here are the details:
We have an mxml file and a few custom components associated with it. 
Each component / class handles a particular type of data. E.g. users / 
documents etc.

When we request to fill the dataset, we get the "Didn't recieve an 
acknowledge message" error. Yet, in two places the data gets filled and 
in one it does not. We still get the error message on all three.

We have similar code in all three classes. We can even see the data 
coming in from FDS on the FDS server console. But it does not come in to 
Flex. Checked the AS file related to the service, but that looks ok too.

Any ideas?

Re: [flexcoders] FDS - Problem configurating message destinations

2006-04-19 Thread Nirav Mehta



Hi,

This may not be relevant, but it's something we struggled with FDS so I 
will share.

We had CF running on the machine, setup FDS and the built in JRun 
server. Made all the changes to the .xml files.

The java-dao examples worked well, but when we moved to CF, it started 
giving weird problems.

Specifically:

'Error invoking fill method flex.data.adapters.javaadapter$fillmethod
exception is : java.socket exception: software cause connection abort: 
socket write error'

And this was because of some unmarshaling exception.

We went beating around the bush for four days.

Then figured that the problem was because we installed FDS in 
"C:\Program Files\Adobe\Flex Data Service" folder, instead of the 
default "c:\fds2". Looks like it could not handle the spaces in the path.

When we moved the installation to the default folder, it started working.

:)

We are using ffmpeg for an app and it's working well - it does have some 
issues with digital camera videos, but we didn't have our videos coming 
from digital cameras so it was ok. On2's Flix is good too - pricing is 
$2500 per site.

We didn't find much else that would work on Linux and especially from a

With Flash available on more than 98% of browsers, people do let go HTML 
version of the Flash content. Developing an HTML version of your 
application may not also be feasible.

I agree that doing HTML version may be the only available solution right 
now, but how about Flex itself generating that version? I know there are 
many complications in this - and some things impossible, but it could 
really allow a lot more people to move to RIAs.

I do not know the internals of SWF format, but is it not feasible to 
have some intelligent SWF parsers that can handle such situations?

I wish the day comes soon, when we can create a complete app like that 
in Flex - ensuring SEO requirements are met ;-)

Re: [flexcoders] Re: RIA Certified Developer/Architect

2006-03-03 Thread nirav
Hi,

Slightly off-topic, but here goes:

On the topic of certification, how about creating a community driven Flex
certification? We have a project - www.opencerti.com - where we have
started out with PHP certification. I was talking to my team and they were
excited to contribute to a Flash/Flex/RIA certification. And I said let me
see how the PHP certification works out and then we can do Flex as well.

OpenCerti is not run by any organization. It's a community project. If
there are people on the list who want to take leadership on the Flex
certification, please contact me off list and we could take it up.

There are a few issues that we are discussing about a community
certification on the opencerti yahoo group - credibility, sustainability
etc. And you are most welcome there as well.

[flexcoders] positioning - absolute / relative??

2006-02-23 Thread nirav
Hi,

We have a menu that needs to be displayed right below a label. The menu
shows up on mouse over of the label.

It works well with fixed x and y positions in menu.show(). But the menu
shows in the wrong place if we resize the window. The menu would show at
the original x and y positions and not relative to the new window size.

Tried to find out the x and y of the hbox the label is in and then work
the menu. But the position is always the same, no matter what the size of
the window is.

Our application does not take 100% screen - it is centered.

How do we get the x and y coordinates to display the menu at?

TIA.

RE: [flexcoders] WebService: SOAP and PHP5 on Apache

2006-01-26 Thread nirav
Hi Jan,

I haven't tried Flex 2 with PHP5 Webservices yet, but we have encountered
many issues working with Flash / OpenLaszlo and PHP5 web services.

A few tips:
1. Make sure your WSDL is correct. I generate it using Zend Studio.
2. Don't pass associative array to the webservice. Use classes instead.
The classes will come in the WSDL and then both the sides can easily
understand what's being passed around.
3. I prefer using the setClass() method, instead of adding individual
functions.
4. Debugging can be trickly. All you may get on Flash side is a fault. We
write to a log file and test. We also create test cases in PHP before we
integrate with Flash.

HTH.
