[flexcoders] Programatic Deletion in Tree causes Error #1010:

[Shailesh Mangal]

All, 

   We have few tree structure in various TitleWindow containers. Some of these 
Trees have data dependency e.g. deleting one node could cause deletion of 
another node and vice versa. What we are noticing is that when we 
programatically delete the nodes (as a result of deletion of a another node in 
another tree), the node does disappear from the tree but and expandItem 
operation causes following stack trace:

TypeError: Error #1010: A term is undefined and has no properties.

This also causes a big white patch in the tree and tree is no more navigable 
after this error. 
We do call validateNow() after deletion is completed for all the effected 
trees. It appears that  (rowIndex + rowsToMove) and listItems[i][0] are out of 
sync but what caused this discrepancy.

I already have a C++ dll that I have invoked with flex on the

compile the dll into some format on Mac and then communicate back

I have seen some open source bridge projects that enclose flash

Is it as simple as doing some Netstream class from flex to connect

there are on Windows) and just do a localhost communication back and

 because, first you need to implement all Channels (or at least one

 trivial. You need to figure out how to make HTTP calls (URLConnection
 vs. HTTPClient), figure out how AMF serialization/deserialization is
 going to work, etc. 
 
 After you have your Channel, you need to implement Producer/Consumer
 so you can do messaging. And finally, you can build DataService on top
 of those.

[flexcoders] LCDS Performance (hibernate cascade)

[Shailesh Mangal]

We are using LCDS 2.5.1 and have a bit of a strange need. Here is a
simplistic Object model.Object A --- Object B Collection
[One-TO-Many]
Object B collection can be really huge and the relation between A and B
is not need on the client but is needed on server so that we can take
advantage of hibernate cascade for bulk operations. Here are my
queries:
1. Is there any way that I can ask LCDS to ignore Object B collection
completely e.g. some configuration in meta of
data-management-config.xml 2. We are thinking of writing a AOP
interceptor where we will manually nullify Object B collection whenever
assembler get involked. While this option doesnt sound very clean, is it
even feasible? It will surely add more complexity in code.3. Should this
be a Managed relation or Hierarchical in
data-management-config.xml?4. Any other techniques?

[flexcoders] Switching between RTMP and HTTP

[Shailesh Mangal]

We are using RTMP as our main protocol and HTTP as a fall back. I have bunch of 
questions.

1. We observed that when RTMP fails, DataService in client automatically falls 
back to HTTP. 
But when RTMP comes back, it doesn't reconnects and continues with HTTP. Is 
there an API to 
do this (other then client attempting to connect periodically)

2. How does RTMP fall back on to RTMPT (Tunnel). Is there any configuration for 
this?

3. DataServiceTransaction doesn't seem to work in case of HTTP mode. Is there 
any work 
around to push data from server to client in case RTMP is not available.

4. When RTMP becomes unavailable, does message subscriber and publisher have  
to re-
connect to server?

Has anybody experienced these issues? WIll appreciate any quick help.

[flexcoders] Re: LCDS - Rollback in dataService doesnt work

[Shailesh Mangal]

We finally figured out the issue, here is quick description

Problem:
Object Graph:
 A -(1 - many) -- B -- (many to 1) -- C

Each of these object has a corresponding assembler with relationship
defined in data-management-config.xml. Say - AA, BA, CA
In UI, I have Corresponding DataServices say AS, BS (there is none for C
as C get fetched as part of B)

If There is a change made on object C, the change is not collected by AS
or BS (although they show commitRequired = true). Rollback on AS and BS
doesnt do anything.

Solution:
 create a dummy* dataService corresponding to assembler CA and call
rollback on it.

Dates are marshalled fine (use java.util.Date). Issue seems to be with

[flexcoders] Re: Access MySQL directly from Flex client

[Shailesh Mangal]

Thanks Beau,
   Apart from the concerns that you have pointed out, we saw another
concern around connection leak (each client needs a connection). So this
is what we ended up doing.
1. Hourly Cron job on database server which spits out the xml (straight
from mysql) and ftp to a secure location.
2. Flex client read those secure files and parses them and draws the
charts and datatable in dashboard with configurable refresh rate.

 Honestly, even if you go the route of AMFPHP or a simple SOAP
webservice
 layer (like PEAR�s Services_Webservice package), it�s really
easy to create
 a service for your specific needs.



 AMFPHP is probably the easiest in the long term as it doesn�t
require you to
 do a lot of XML parsing to access your data. However it is a bit more
work
 up front. Setup is easy, but you have to create VO�s on both
sides.



 Services_Webservice is just a standard SOAP wrapper for PHP. A little
more
 involved to setup as it doesn�t have a default service broker
(though it�s
 not hard to make one) but doesn�t require VO�s, but like I
said, you have to
 parse through the XML in your client � not that it�s hard.



 Both methods involve creating PHP classes with public methods as your
 service interfaces. With AMFPHP you simply put these classes in the
 amfphp/classes directory. Services_Webservice you extend the
Webservice
 class and load it through your broker.





 Hope this helps,



 Beau

[flexcoders] Re: Flex Data Management and container's UserTransaction

[Shailesh Mangal]

Turned out that Its not the transaction, its OpenSessionInViewFilter's
flag for singleSession which caused my updates fail [For reasons not
known]. 
So, in a nut shell, If you have,
1. singleSession = true, DataServiceTransaction wouldnt send out the
updates
2. singleSession = false, DataServiceTransaction send out the updates
just fine. (problem with this approach is bulk operations will exhaust
resources as every request will fetch a new session object)

Will appreciate comments if any one has witnessed the same behavior.

  Subject: [flexcoders] Flex Data Management and container's
  UserTransaction
  
   
  
  As I understand Flex Data Management Services require that application
  container provide UserTransaction for it. But I can't find any guide
  about how FDMS uses it.
  
  I was completely confused when I checked several tutorials that used
  FDMS+HibernateAssempler+Spring or FDMS+hand written
  Assempler+Hibernate+Spring. 
  
  That tutorial 
  http://blogs.adobe.com/mtg/2006/08/my_first_hibernate_enabled_fle.html
 
http://blogs.adobe.com/mtg/2006/08/my_first_hibernate_enabled_fle.html
  
  specify that Hibernate's SessionFactory use datasource not tied to
  global transaction manager.

  don't specify that SessionFactory should use global transaction scope

  So what's the purpose of FDMS to have reference to container's
  UserTransaction?

[Shailesh Mangal]

Thanks Jeff. 
1. This is all happening in remote Service (I dont have access to
assembler's transaction there). Hence I am creating new
DataServiceTransaction. Does refresh and update happen on a different
thread? For assemblers, I use Hibernate Interceptor which works great.

2. singleSession = true binds a session to a threadLocal, so the same
session should be available to all as long as its happening on the
same thread

3. If we have one-many relation(parent child) in assembler, which
points to the same assembler. If a child changes outside of the scope
of the assembler, do we need to send refresh on the child only or
parent only or the recursively from top most parent to bottom most child.

 Hi Shailesh,
 
  
 
 I'm not sure what the problems are...  It sounds like you are using the
 DataServiceTransaction.begin() and commit() methods yourself (the other
 way this can be used is if you call the
 DataServiceTransaction.getCurrentDataServiceTransaction() call from
 inside of an assembler method such as createItem).  When you call
 begin, if you specify useJTA=false I think that when you call commit()
 on the data service transaction that those calls should go out no matter
 what.   By the time this calls is made though, we will assume that the
 changes you are telling us about have been applied to the data base and
 either have already been committed.  It could be that you are calling
 commit() just before the transaction has been committed?The part
 that could go wrong there is the refresh fill process.  If you call
 createItem() and then commit(), the commit will go through each
 managed fill and potentially re-execute those queries to pick up the
 newly added item.  If this fill call re-queries the database so it does
 not see the change applied, it would not refresh it properly.
 
  
 
 It might be that in one mode you are using the HibernateAssembler picks
 up the same session and so sees those changes and in the other mode is
 picks up a different session?  I'm not sure... if you still have
 questions and can generate a server debug log for the problematic case
 I'm happy to take a look.

 Turned out that Its not the transaction, its OpenSessionInViewFilter's
 flag for singleSession which caused my updates fail [For reasons not
 known]. 
 So, in a nut shell, If you have,
 1. singleSession = true, DataServiceTransaction wouldnt send out the
 updates
 2. singleSession = false, DataServiceTransaction send out the updates
 just fine. (problem with this approach is bulk operations will exhaust
 resources as every request will fetch a new session object)
 
 Will appreciate comments if any one has witnessed the same behavior.

   There are two use cases where we DMS will use the UserTransaction. 
   
   
   
   1) When your assembler has use-transactions=true, and you
 commit
   a change or batch of changes, the DMS code will start a transaction
   before calling your createItem, updateItem, and deleteItem
 methods. If
   any of those get an error, the transaction is rolled back and all
 of the
   changes are put back into the uncommitted list on the client. If
 they
   all succeed the transaction is committed and the changes pushed to
 other
   interested clients.
   
   
   
   2) If you use the DataServiceTransaction api to push changes
 from
   the server, when you call begin you can pass in a value of true
 which
   causes the DMS stuff to start a JTA transaction in that call. 
 When you
   call commit, the JTA transaction is committed if the setRollbackOnly
   call was not made. This is just a convenience if you happen to have
   some JDBC code which is updating the database

[flexcoders] Wierd LCDS behavior

[Shailesh Mangal]

All,

We observed a strange LCDS behavior. We have tried all other
permutation and combinations of this that we could think of. Any help
is highly appreciated.

Here is Object tree, collection of A is bound to a tree and collection
of B is bound to a grid in the same canvas

 A
 |
 -- Child Collection[A] (one to many)
 |
 -- Parent [A](Many to one, read-only=true)
 |
 -- Another Collection [B]  (one to many)

B
|
 Another Object [C] (many to one)
|
 Another Object [A] (many to one)
 
All the relations are managed in data management_config. Everything
works fine if collection B (inside A) is empty. But if collection B
has some data in it,  we get following behavior:
When we delete the top most items or their immediate children in the
collection, everything works fine and items disappears from the tree.
But we go two level deeper, the item gets deleted fine from database
but we don't get updates and UI keep showing the item in the tree. If
we attempt another delete operation on the same item, it disappears
from the tree also.

  If anyone interested, I am happy to share our datamodel / relevant
object classes.

It was a working FDS project and had only one messageBroker Servlet
configured. I just applied 
1. SDK HotFix-2 and HotFix-3
2. Copied over following from within flex.war
   a. /WEB-INF/flex/jars
   b. /WEB-INF/lib/
   c. /WEB-INF/flex/libs

to their corresponding folders in the existing project. Is there
anything I am missing.

[flexcoders] Upgrading SDK to HotFix3 and FDS to LCDS 2.5

[Shailesh Mangal]

We are trying to upgrade our existing FDS project from Flex SDK 2.0.1
to HotFix2 and HotFix3 (which also require upgrading FDS to LCDS 2.5).

1. Is there any reason not to upgrade? The only reason this is a
confusion is that in the KB, Adobe suggests not to unless you have
specific problems.

2. There is no LCDS version for MAC
(http://kb.adobe.com/selfservice/viewContent.do?externalId=kb402000sliceId=2)

How to upgrade it on mac. 

Will appreciate if some one who has done similar upgrade can share
their experience.

[flexcoders] Re: Jetty with JOTM causes ClassCastException in FDS

[Shailesh Mangal]

Thanks Jeff,

I was able to get a stand alone Tomcat working. But for a speedy
development embedded server make so much sense. 
Further, our team is used to running Tomcat/Jetty inline (via Maven).
For some reason that configuration is not able to load the
UserTransaction. 
Will try to switch off JTA but I am afraid when we actually deploy, we
might have some unforeseen issues.

 When you use Data Management Services to update objects on the server
 side, and your destination has use-transactions=true, FDS will create a
 JTA transaction before it calls your assembler methods.  The problem you
 are running into is that this code is failing... it is a pretty standard
 set of features for a J2EE server though servlet containers don't
 usually support JTA out of the box.   You might be able to workaround
 this problem by setting use-transactions=false on your destinations
 though you'll still need JTA libraries to be available to satisfy
 linkage.

[flexcoders] Re: Flex + Struts

[Shailesh Mangal]

Do you run tomcat using maven plugin (maven tomcat:run)

I have a tomcat that runs stand alone but the embedded server fails in
JNDI (tried both jetty and tomcat). 

Any one using embedded J2EE container?

 the jars to WEB-INF/lib. JOTM is for use with Tomcat (servers without

[flexcoders] Jetty with JOTM causes ClassCastException in FDS

[Shailesh Mangal]

Hi All, 

   After struggling for a quite a while, I was able to configure Jetty
with JOTM (to a point where it starts cleanly).

Now I am getting a ClassCast Exception in JNDILookup. Wondering if
anyone has come across following error (FDS output in Debug mode).
Same issue is discussed on in decent depth,
http://tech.groups.yahoo.com/group/flexcoders/message/51486 but no
concrete solution suggested.

 yeah, jboss is a JEE application server so I think JOTM is part of the

 should go more smoothly than tomcat since JOTM came out of the jetty

 If it had turned out to be much harder than it actually was I probably
 would have switched. But as it turns out the biggest issue with using
 tomcat is the documentation, not the actual process.

   Couldn't agree with your comments more... I burned about 4 hours the
other day trying to get FDS up and running with Tomcat (will
have to
try your clearer instructions on the JOTM install, as I tried the 2
sources you mentioned and did not get anywhere).
  
In Adobe's defense, I don't think it's just them, the Java
community
seems to have so many amazing platforms and frameworks, but
there's so
many that just accomplish the same thing, and in general,
there's no
simple documentation on installation or usage that makes any sense.
Sometimes it seems like it takes 6 frameworks running around
the clock
to print out 'hello world'. :)
  
All that being said, I'm sure that once Flex 2 goes GA, we'll
see much
better documentation on all of this. They are probably a little
busy
right now...
  
Thanks again for the instructions though, I'm sure these will help
many who found the JOTM instructions cryptic before.

[flexcoders] Titlewindow dragging and dropping within canvas

[Shailesh Mangal]

I need to put a titleWindow over the canvas (either as a child or as
popup) and should be draggable by it titleBar (and not the body)
confined with the canvas and should not flow over other components on
the screen. 

I did it successfully by implementing custom dragging but that lets
the whole titleWindow draggable.

Tried with Popup manager but drag events dont get bubbled up except
close and mousedownout. I need to capture dragComplete to make confine
the dragged component into a defined boundary. I tried dragComplete on
the dragged component. 

Are there alternative ways to do this?

mx:HTTPService id=xmlPoster2 url={loc + 'coveragemap'}
method=POST resultFormat=e4x contentType=application/xml
result=showMap(event)/

public function showMap(event:ResultEvent):void{
trace(event.result);
var res:XML = event.result..marketValue as XML;
var imgName:String = res.toString();
imgSrc = assets/img/ + imgName;   
coverageMapBox.setVisible(Boolean(true));
}

[flexcoders] Re: problem in parsing xml return by HTTPservice, could it be namespace issue

[Shailesh Mangal]

I figured this out. Here is what worked for me.

var res:XML = event.result as XML;
var ns:Namespace = res.namespace();
var imgName:String  = res..ns::marketValue;

:: operator is the key.

This works well for the defualt namespace. I still havent figured how
to access an element whose namespace different then the default
nameSpace and is not known.

 Uisn the index will work but it would be much better to figure out the
 namespace problem.  I am currently working on an example to learn about
 namespaces myself.
 
  
 
 Ben Clinkinbeard has posted on this issue often and he has some examples
 and discussion on his Blog.  I plan to head over there and start
 studying when I have a bit of spare time.

 You try what I used to solve the same kind of problem
 
 event.result.record[0].myFieldName
 
 where my XML looks something like this
 
 records
 record
 myFeldNamemyValue/myFieldName
 /record
 /records
 
 Thanks to Tracy Spratt for revealing access to the 
 XML more directly via event.result !

  Here is the xml I get back from my HTTPService call

  com:statusCode xmlns:com=common0/com:statusCode

  /res:message
  
  but when I try to use .. operator for marketValue node, I get null
  object back. Any suggestions. I tried use namespace also, didnt

[flexcoders] Re: remote sandbox security problem for mx:HTTPService

[Shailesh Mangal]

I ran into this same issue. How to use Proxy?

Is it because I am using eval license of the builder.

 mx:HTTPService
 
 Hi all,
 
 My app works well when I launch it as a local
 sandbox but when I put it in my tomcat webserver the
 sandbox is now on state remote and all the http
 service call failed.
 
 The only way I found is to put a crossdomain.xml in
 the root of all servers I call ! (which is not
 possible for a real deployment)
 
 = Is there a way to create as we do in java a policy
 file on the client side or a certificate to trust the
 swf file ...
 
 
 many thanks for help

[flexcoders] Re: source code of Training from the Source

[Shailesh Mangal]

I know, but my copy is no more usable. Wondering if any one can share
theirs. You can send to me the zipped version on my mailID.
