CF/Flex Application Wizard Details Page
Hi,
Not sure if this is possible (seems like it should be). I
have the following data model in SQL Server (2005):
table name (relevant columns)
person (first name, last name)
member (member number)*
contact (email)*
location (state)*
Person is the base object/table and the other three tables
have foreign keys connecting them to the person table (all have a
personId column).
I setup a master page, no problem. I can grab the person's
first and last name, member number, email and state and display
them on the member-master page.
The issue comes when I go to create a member details page. I
can step through and create the necessary form fields from the
tables (connecting them all via their common personId column). When
I go to save the detail's page details, Eclipse (v3.2.x) crashes on
me. Every time. However, if I only create a form for the details
page with two tables (say member and person data), I can create the
details page and use it without any issues.
To get around this seeming two-table limitation, I edited the
Adobe/CF generated content to manually add the beans, DAOs,
gateways and AS files for the other tables. Doing this does create
the desired details page, however, Flex and CF are REALLY slow to
grab/return the requested data to the respective form fields (and
there is not that much to grab in any of these tables).
I'd like to know if this is just how I have to go about it.
Does the CF/Flex Application Wizard have a limit on how many tables
can be joined in a details page?
I have a project with a much more complex data model and
would love to generate a quick application for my client to check
out and I do not know if I've encountered a limit of the
application or if I am doing something wrong in the Query Builder
itself?
Also, any thoughts on why Flex and CF would be so slow to
return the data when I manually added the other tables to the
details page form? I'm on an intra-office network, connecting to a
computer via an ethernet router and the sample DB only has 2000
records in it...all with simple text and date columns?
Sorry for the long post and thanks, very much, in advance for
any thoughts or advice.
Best,
Craig
Never mind, I figured it out.
I'm Using IIS
I needed to go look at the properties.
On the web site tab, the TCP port was set as 80.
In FlexBuilder Window > Preferences > Cold Fusion >
RDS Configuration
Select localhost > The default port number added there was
8500
Once I changed that to 80 and clicked on test connection, all
was hunkey dorry

Cold Fusion/Flex Application Wizard crippled in Trial Version?
Hi,
I am using the 60 Day trial version of Flex Builder
3/Eclipse.
I wanted to try out the much vaunted Cold Fusion/Flex
Application Wizard, mainly because I could not get my head around
access from Flex to an existing CFC from the documentation alone.
So, I followed the directions:
Click the plus sign (+).
In the Name: text box, enter the name for the page.
Select the page type (master, detail, or master/detail).
Click Edit Master Form or Edit Detail Form, depending on the
type of form you are creating.
The Visual Query Builder starts.
But for me, when I click on 'Edit Master Form' the Visual
Query Builder does not start.
Now I have checked and confirmed that my RDS is working, and
that I can access the database via RDS in the Eclipse RDS browser
window. The RDS concerned is on another PC.
The PC on which Flex Builder is installed is a Vista
Ultimate/32 and the database is MS SQl server 2005 (running on the
other PC). Cold Fusion 8 is installed on both PC's.
So, my question is 'Is the CF/Flex Application wizard
deliberately hobbled/crippled in Flex 3 Trial version, or is there
something wrong with my installation.?
If this works for everyone else, then how do I debug my
installation ?
Thanks,
Bryn Parrottin addition, I can say that I installed the same flex builder
trial on an XP machine, using its own local RDS, and found that the
wizard worked just fine.
So what is the variable here, why is the wizard not working
on the vista PC ?
Is it Vista ?
Is it the fact that I'm trying to use RDS against a remote
server and not the local one ? -
Problems with ColdFusion Extensions and CF/Flex Application Wizard
I have configured the Eclipse RDS according to the
instructions in the help documentation. The RDS Fileview and
Dataview work OK, but I haven’t had any luck with the
Services Browser: when I try to expand (+) the localhost item, the
only thing that appears is the message “Unable to get meta
data for cfc.”
The Dreamweaver 8 Components panel, which shows exactly the
same information, works fine.
Perhaps related to the above: when I create a Flex project
with the CF/Flex Application Wizard and look at the project
properties, in the Flex Server section, I get "Since this project
does not use a server, these setting do not apply". I find this
odd: a ColdFusion project that doesn’t use a server? Anyway,
using the wizard, I have not been able to create a simple project
that works.
If anyone has had similar problems and has been able to solve
them, I would appreciate some light on the subject.
CarlosWell I was able to resolve this problem by un-installing and
re-installing CF.
I did some further testing (un/re-install again) and it
appears that this problem occurs when CF is installed in devnet
version mode and not if in developer mode.
To check if CF is installed in devnet mode look in the CF
Administrator under "server settings->settings
summary->version information" You will see a notation for
devnet.
I also did a little poking around and this happens whenever
you install CF using a certain range license keys. The keys in this
range are valid keys for installation but they alter some critical
settings in CF (the flash paper/pdf watermark and apparently some
RDS stuff) The solution is to install with a non dev-net key or in
developer mode. -

ColdFusion / Flex Application Wizard Problem
I can't get this to work.
On the last page if I do a new project location I get:
The project could no be created. Please check the webroot
folder (it may overlap with an existing project).
If I try to use an existing project it looks like it does a
little, but doesn't complete and stays in the last screen of the
wizard.I just found this in an error log.

Coldfusion / Flex Application Wizard
When using this wizard, it assumes that the project is going
to be created one level under the web root.
If you have the following path
webroot/flexprojects/projectone/
Then you wanted to create a db table maintenance project
(called 'maint') at the above location, the following happens.
When the wizard creates the pages and inserts the code for
the remote object, the source will be missing
"flexprojects/projectone" and thus there will be an error.
Does anyone know how to overcome this ?
KenSame problem here. I've tried it on 2 computers, both running
Windows XP, and almost immediately after the install, so no other
projects are present. How do you get past this problem? -

in this application one more problem is also their,
background image loads very slow, before it loads all the flex

background image loaded, to move to next and back pages.
Thanks for your time and consideration.

Spring Flex application on weblogic 10.3
I have developed an Spring-Flex application. I did the necessary changes to be done in web.xml, spring-config.xml and services-config.xml. The application is working fine on Tomcat server. But when tried deploying .war of the application on Weblogic 10.3, the navigation of the application is failing. Even the messagebroker defined on startup page if not receiving.
Is there any server specific changes need to be done on Weblogic before deploying the .war file?
Please provide the pointers.Hi,
Did you configure your application module to use a JDBC data source? To do this, right-click the app module in the navigator, select Configurations and in the dialog that comes up change the connection type to JDBC Data Source and enter your data source name - which should be the same as the data source you created on the weblogic server.
Also, I do suggest you create an EAR file - this is what we've tested and certified with. You can find more details in the deployment chapter of the fusion developer's guide: http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/deployment_topics.htm#CHDJJDDG.
Hope this helps

Performance Of Flex Application?
Hello all
Recently I went through video tutorials of flex and found it to be great.But I have one question regarding performance. If I am not wrong then Flex application works like this, Entire application is converted into swf file and for navigation between pages of application there is concept of states.Whatever data is required for different states is get by using HTTPService,WebService etc . wheras if we talk about normal web application built using PHP every page and data is loaded from server .For each navigation, data plus markup(HTML/DHTML CSS javascript etc.) to show that data or content is loaded.It has a benefit of downloading only that part of application which is required.
For example if we have shoping store applicatiion and it has a search page and product list page to display products list in different formats like grid or table then markup plus data in normal web application will be loaded with each request.If user click on search page only then that page is loaded from server and if user want to view the search results in table format only then that page is loaded.
I want to know how this work in Flex application.For data part It is clear that for each state whatever data is required is get by using services like HTTPService,WebService etc. But how state presentation part is get?Is the entire swf file containing all states related information is loaded before running the applicatio? For example as in our previous example presentation part of all states like shopping store serch state, product list in table format state and product list in grid format state in the begining of application .later on if user click on search link it will already have that state view information and it will get data for search part and put that data into view and present it to the user.For search result also it will be already having information about how to present that data so it will get data only and present it to user.
If Flex works as i stated above then if we have very big application with many different stats then user has to wait for the loading time off all the states.Or there is provision for some backgroud loading of states that as soon as user request the application first time he gets the first view and then on other states are loaded in backgroud?
If all the states are loaded at begining of application then what will be performance of application with many states?(Means in that case swf file of compiled application will be of big size and it will take time to load in browser.)
can anybody tell me about all these things in detail.I am sorry if my understanding of Flex is wrong.I am newbie.
Thanks in advance .This seems more of an RIA performance question than a Flex specific one. Honestly though, modules aren't needed often in my experience (depends greatly on requirements).
You say that "only the part of the application that is needed" is downloaded, while this is technically true (a bit of an oversimplification as there are other advantages to be had from RIAs), you still have the round trip time required for every single request to the server. Since an RIA is generally a single bulk download (which may not even be needed if there's caching going on), usually you're talking about a single wait of a few seconds for loading vs multiple waits of a few seconds for page refreshes.
Even if the initial load time is as much as ~10 seconds (for the first visit), does that outweigh the 1 to 3+ second page refresh penalty constantly interrupting the user's work flow over time? Also consider Flex's AMF protocol, which blows competing formats (esp XML based) out of the water on performance. RIAs (especially Flex) win the performance game. -
Coldfusion Application Wizard?
I was trying to access the Coldfusion Application Wizard in
Flex 3 Beta and it told me it's unavailable. So I switched back to
my install of Eclipse 3.2 with Flex 2 and I don't have an option

Other. Can anyone supply a link to where I can download the
Application Wizard? I looked on labs.adobe.com but I didn't see any
Coldfusion extensions.
Why doesn't it work in Flex 3? :)
Thanks!
MikeHi Randy,
Are you on Windows or Mac? Also, if you could check the
Eclipse/Flex Builder error log to see if any errors were logged at
the time of the crash, that would be very helpful. The error log is
a text file called ".log" in "<workspace-dir>/.metadata". You
can also access it through Flex Builder, by going to Help >
About, then Configuration Details, then View Error Log, or
something like that. -
Use BAPI_FLIGHT_GETLIST from a standalone flex application
Hi all,
I am able to get the flight details [ BAPI_FLIGHT_GETLIST] using flex when run from BSP page, but if i embedd the same swf file in a HTML file or run in flash player i am not able to get any details even it is not asking for my server uname and pass.
Wat to do to fetch the data using this standalone swf files.
jayHi Jay,
It'd have been more clear if you had posted any error/exception you faced in this situation.
Still I can suggest you check wsdl link you mention in Flex application.
i mean if you have use any alies name like localhost etc insted of your R/3 IP XXX.XX.XX.XXX:ZZZZ.
In Above Line Replace XXX.XX.X.XXX:ZZZZ with <Host IP>:<Port>.
Further check that RFC is only at basic authentication and not customized authorised Very rare possibility if you can be sure.
For your help you can refer sample code on following thread for same functionality you want.
Web service call in Flex
You can make AIR application also using same code. Just a small change to be used under WindowedApplication tag.

Vivek
