[transfer-dev] Re: Anyone doing / soon to be doing Flex work with Transfer?
Mark, Me, too. I have one client for whom I have done a public-facing application using Transfer, and now we're getting ready to build lots of internal management applications. Those apps will be primarily (or all) in Flex, and I'm certainly planning on using Transfer. I also have another project in the planning stages, to manage drug research studies. It'll be Flex, too, and I was planning on using a Transfer/ColdSpring back end. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 --~--~-~--~~~---~--~~ Before posting questions to the group please read: http://groups.google.com/group/transfer-dev/web/how-to-ask-support-questions-on-transfer You received this message because you are subscribed to the Google Groups transfer-dev group.

[transfer-dev] Date value difficulty when passing to Flex
I'm having difficulty in getting Flex to recognize date values that are coming out of a Transfer object. The object being sent to Flex is a typed struct, and it is recognized as the correct object. If I create the typed struct directly from a cfquery, the date values are correctly typed. Charles shows, for instance, Date Reference Nov 24, 2008 3:59:54 PM. And that value is correctly converted into a date in Flex. But if I create the struct by calling getters on a Transfer object, the values are typed as strings, and fail to convert in Flex. For example, the same date above is shown in Charles as String Reference 2008-11-24 15:59:54.047. I've worked around it by creating date/time strings, then using parseDateTime before returning them. But this seems a bit clunky, and I'm wondering if there's a better solution. Has anyone else noticed this behavior? -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 --~--~-~--~~~---~--~~ Before posting questions to the group please read: http://groups.google.com/group/transfer-dev/web/how-to-ask-support-questions-on-transfer You received this message because you are subscribed to the Google Groups transfer-dev group.

[transfer-dev] Re: Transfer BER functionality - Code Generation Toolkit
So ... except they either need to be dynamic objects, or implement an Interface (there needs to be a property to store some data in). Oh and they need to be defined as [Managed], as I hacked [Managed] in the same way dbHibernate does. (Big credit to Andy Powell and Mike Labriola for being huge helps on this). Okay. So I need to read up on dynamic objects and what the [Managed] metadata implies. I can do that. But if there's anything specific that you can point me to that will be most helpful, great. From there there is a TransferRemoteObject.as with which you need to make remoting calls with, so we can track incoming TO. Okay. I knew there was an ActionScript piece that had to be there. Do the VOs need to extend the TransferRemoteObject, as a decorator does the server-side TO? And -- where would that TransferRemoteObject.as be? I can't find it in either the Transfer or Conduit packages. And I assume that the transferFlex.swc needs to be loaded as a lib into the Flex app, right? You can configure the lazy loading with a 'lazy' attribute on the cfproperty tag, and that occurs automatically on the Flex side, although if something isn't loaded it will return NULL. You can check if something is lazy loaded, by checking the __lazyLoaded dynamic Object that will be a property on the Object. I understand that -- sorta. I'll have to look at the object to get it. There are also custom LazyLoaded events that fire when a value is loaded, and PropertyChangeEvents are fired, so you can use binding a lot with these VO's. I'm guessing I can learn about this from looking at the TransferRemoteObject.as, right? Last question, is there any simple POC that you've created, beyond the unit tests, that you'd be willing to share at this point, in lieu of documentation? -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 --~--~-~--~~~---~--~~ Before posting questions to the group please read: http://groups.google.com/group/transfer-dev/web/how-to-ask-support-questions-on-transfer You received this message because you are subscribed to the Google Groups transfer-dev group.

[transfer-dev] Transfer EmptyQueryException
I'm well aware of Mark's requests for configuration information when reporting problems. And if folks decide it will help, I'll include it. But it doesn't seem that it would be particularly useful just yet. Here's what's happening: I have an application that has been running on CF8 Standard/Win 2003 server on a production server, and on my dev server, it is now running on CF9/Win Server 2008 (all 32-bit). I'm setting up a new server now, which is a 64-bit Win Server 2008 machine with CF9. The application is accessed through a Flex front end. All flex config files are identical on the dev CF9 and the new production machine. In my initial testing, most everything works fine. But certain methods fail with an EmptyQueryException -- *only* when called from the Flex app. I have not been able to find any commonality among them. In one case, the failure comes on the call to an array of one-to-many objects from the parent; in another, it fails when manually looping over a set of ids, getting the matching Transfer object, and putting the objects into an array. In a third case, it fails when retrieving a Transfer decorator in order to update values. I can see that the input parameters are being sent correctly to the server. And in one case, there are no parameters. The method is simply a call which kicks off a hard-coded Transfer.list operation. So it can't be the input that is failing. And as I say, these failures only occur when done through Flex. I have built a test page which calls these same methods through their remote proxy, just as the Flex app does. The call goes to the proxy, to a service, to a gateway and back. Everything comes back perfectly. It boils down to this: certain methods fail when called from the Flex app, but work when called from a standard .cfm page. Although the exception info doesn't provide a stack trace, I'm guessing that this may be a cache-related failure. Maybe? Cache is set to instance, by the way? Has anyone ever seen anything like this? -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 -- Before posting questions to the group please read: http://groups.google.com/group/transfer-dev/web/how-to-ask-support-questions-on-transfer You received this message because you are subscribed to the Google Groups transfer-dev group.

As an update: As I move through more and more logs, I'm finding similar NullPointerExceptions that have nothing to do with Transfer. So whatever's going on is evidently not Transfer-specific, so we can probably let this thread go.

Hi Mark, On Tue, Feb 9, 2010 at 2:20 PM, Mark Mandel mark.man...@gmail.com wrote: Sounds like a bug in CF9. While there seem to be some known issues in CF9 regarding serialization of aliased CFCs, I've found (since the last post) that I was wrong in pointing to CF9. Going back to the previous production environment, which was CF8, I also see a trail of NullPointerExceptions during January. They were in the JRun logs but not the CF logs. They seem to relate to three particular method calls, but so far, I haven't found anything in those methods that could cause the error. In fact, I can replicate one of the errors now (although it occurs inconsistently). But here's the odd part: when I view the transaction in Charles, I see: two requests go out with the same method call. I don't believe the event is being fired twice in Flex, but I haven't yet been able to check that thoroughly. It could be that I'm inadvertently dispatching twice. However - the two requests go out relatively simultaneously (same second, anyway). When there is an error, one returns a NullPointerException; the other returns the correct array of objects expected. I have checked the params being sent in each request; they are identical. Additionally, while duplicating the call with the same params again seems to result again in two requests, I received the correct response from both requests. So I'm guessing (and I really mean _guessing_) that the failure is somewhere in the serialization process. I do know that I recently had a different issue where the wrong data appeared to be returned to Flex, and I was able to prove (to myself, anyway) that the same call with the same params to the same proxy CFC produced different results when called from a plain .cfm page than when called from the Flex app. I'm checking into the bug tracker, but if anyone has seen anything similar, I'd sure like to know. Since I can't replicate the error consistently, it'll be hard to submit a test case for a bug. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 -- Before posting questions to the group please read: http://groups.google.com/group/transfer-dev/web/how-to-ask-support-questions-on-transfer You received this message because you are subscribed to the Google Groups transfer-dev group.

I've gotten very dependent on ColdSpring. I'm trying to track down the responsible framework. Good luck. My app is running Transfer 1.1.g, ColdSpring 1.2 RC1 and ColdSpring Bean Utils 1.2. My versions of Transfer and ColdSpring are the same as yours. I'm using Brian Kotek's Bean Utilities, but I'm not sure that's the same as your ColdSpring Bean Utils. I have 3 statements for coldspring.beans.DefaultXmlBeanFactory that call loadBeansFromXmlFile(). It's dying on one that instantiates my transfer gateways and service objects.

When I ran into it, I had recently made changes to my Transfer config file and figured I just made a mistake. After commenting out pieces of the file till I had nothing left, I realized it wasn't me.

I have not had time to go any further with this. It concerns me, because it's a pretty important hotfix. But unfortunately, the error messages in ColdSpring leave a lot to be desired, and sometimes point in the wrong direction. I'm going to add mention of this issue in a couple of places: there's a thread on CF-Talk regarding other problems with the hotfix, and there's a string of comments about the issues on Ben Forta's blog.

Re: [transfer-dev] get array of objects from transfer object
Hi Marc, From my experience, I would say the best way to deal with your situation is more or less as follows: Create a getUserApplications method of some sort, with the user as an argument. Within that method, determine whether or not the user is an admin. cfif admin Call another method, getAdminApplications. Within the method, create an empty array (say, arAdminApps). Run your list() method, then loop over the resulting query, using the id for each application to create a Transfer object (transfer.get(), and adding the object to the array, which you return to your calling method. cfelse Do what you're now doing: retrieve the array from the many-to-many association. The need to create an array of Transfer objects is pretty common, and it seems that doing list(), then building the array, is the simplest way. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 -- Before posting questions to the group please read: http://groups.google.com/group/transfer-dev/web/how-to-ask-support-questions-on-transfer Try out the new Transfer ORM Custom Google Search: http://www.google.com/cse/home?cx=002375903941309441958:2s7wbd5ocb8 You received this message because you are subscribed to the Google Groups transfer-dev group.

Re: [transfer-dev] listByProperty with Relationships
David,
I'm not sure of your use case. But it seems to me you may be going about
things a little wrong.
You may or may not know this (and I apologize if you already do), but the
list functions return query lists, rather than objects. So I'm not sure
why you'd do:
var getVariation =
APPLICATION.transfer.listByProperty('catalog.variation','varid',ARGUMENTS.varid);'
You're looking for a single variation, so I'd think you'd simply want to
do:
APPLICATION.transfer.get(catalog.variation, ARGUMENTS.varid)
That would return the object you're looking for. Since Transfer is an ORM,
most of the time, you want objects, not queries, right?
In your second example:
var getValues =
APPLICATION.transfer.listByProperty('catalog.variationVal','varid',ARGUMENTS.varid);
... you're trying to retrieve a list of child variationVals for a parent
variation. That would suggest that you might want to use a one-to-many on
variation, rather than a many-to-one on its child. Many-to-ones only allow
access from one side of the relationship. Thus, from your code, you can do
variationVal.getVariation(), but you have no way to access the children from
the parent.
If you set the relationship as a one-to-many on the parent, you have access
from both sides.
So you'll be able to get the parent variation from a variationVal, by doing
variationVal.getParentVariation(), and get the children by doing
variation.getVariationValArray() (if you set the one-to-many collection as
an array).
Take another look at the Transfer docs on composition and relationships, and
I think you'll get the idea.
None of what I've suggested will give you a query list, which is what you
seem to be looking for. You will always get Transfer objects, singly or in
arrays. If you truly need a query of variationVals, then you'll either need
to _not_ set up a relationship in Transfer, or simply use straight SQL.
Hope this was helpful.
--
Thanks,
Tom

Re: [transfer-dev] Re: listByProperty with Relationships
Hi David, On Tue, Sep 28, 2010 at 10:30 AM, David Long david.lon...@gmail.com wrote: Thanks Tom. That is extremely helpful. Good. Glad to have helped. I am still very new to ORM so I didn't realize that it is better to have an object than a query. Well, the point of using an ORM is to be able to use objects. Otherwise, it's not much of a help. But it's not always better to use objects. Sometimes a simple query list is all you need. And the query list avoids some expensive object creation. As you work with Transfer - or CF9's built-in Hibernate functions - you'll get more of a feeling of what to use when. Good luck. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 -- Before posting questions to the group please read: http://groups.google.com/group/transfer-dev/web/how-to-ask-support-questions-on-transfer Try out the new Transfer ORM Custom Google Search: http://www.google.com/cse/home?cx=002375903941309441958:2s7wbd5ocb8 You received this message because you are subscribed to the Google Groups transfer-dev group.

Re: [transfer-dev] Re: listByProperty with Relationships
David, I'm not certain exactly what you mean about the number of function calls, but depending on how your application scales, you may need to be careful of the number of objects you're instantiating. James is correct, in that Transfer has a solid cache mechanism. (Though you need to remember that Transfer _is_ caching objects. If you update database records outside Transfer, you can get the cache out of sync with the database.) And object instantiation has improved markedly over the past versions of CF. (Don't know which one you're using.) But instantiating an object is _still_ more expensive than just doing a query, if for no other reason than Transfer has to run the query, then populate the object. You have to get the record out of the database at least once for its object to be in the Transfer cache. So there are certainly instances when queries are a better option. For example, your basic States select box in a Name/Address form. Sure, you could retrieve all the IDs from your States table and loop over them, creating an array of State objects, then use that to populate your select box. But why? You don't really need the objects. Better to do: transfer.list(util.state,stateCode), and get a regular old CF query object. As I said before, there are times when you need objects, and times when a simple CF query is better. You'll work it out as you spend more time with Transfer. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 -- Before posting questions to the group please read: http://groups.google.com/group/transfer-dev/web/how-to-ask-support-questions-on-transfer Try out the new Transfer ORM Custom Google Search: http://www.google.com/cse/home?cx=002375903941309441958:2s7wbd5ocb8 You received this message because you are subscribed to the Google Groups transfer-dev group.

Re: [transfer-dev] Re: listByProperty with Relationships
Hi James, I agree with all you say, and have said. And I find Brian's BeanInjector pretty handy, too. I've gotten very used to the idea of rich domain objects. I was just trying to point out to David, since he is relatively new to Transfer, that the excitement over being able to work with objects may need to be tempered by memory and performance considerations. I certainly wasn't suggesting that your comments about the use of objects were in error, or against any best practices. David originally didn't seem to understand that the reason to use Transfer was to work with objects. Then, after my first reply, he was excited about using objects. I was simply suggesting that's there's a lot to learn once you start doing o-o-ish development and start using any ORM. -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 -- Before posting questions to the group please read: http://groups.google.com/group/transfer-dev/web/how-to-ask-support-questions-on-transfer Try out the new Transfer ORM Custom Google Search: http://www.google.com/cse/home?cx=002375903941309441958:2s7wbd5ocb8 You received this message because you are subscribed to the Google Groups transfer-dev group.

Re: [transfer-dev] Transfer returns an array of objects...
James, On Tue, Oct 12, 2010 at 11:27 AM, Clarkee21 clarke...@gmail.com wrote: ... was talking to someone about a month ago about Transfer and how it always seems to return a query result rather than build an array of Transfer objects. Jason is correct. If you have a parent object and have a relationship defined, you can retrieve an array of child objects (if you've defined the collection as an array). But I think you have something different in mind. I suspect you're not dealing with a relationship, but rather simply want an array of objects at any given time. There's no core method in Transfer to do something like: transfer.getArray(user.user). Rather, what you want to do is retrieve the query list -- transfer.list(users.user) -- or listByPropery or listByPropertyMap. This will, as you state, return a query. Then you loop over the list of IDs, creating an object matching each ID, and add them to an array. Something like: cfset var users = transfer.list(users.user) / cfset var userArray = arrayNew(1) / cfset var user = / cfif users,recordCount GT 0 cfloop query=users cfset user = transfer.get(users.user,users.UserID) / (This creates the object) cfset arrayAppend(userArray,user) / /cfloop /cfif cfreturn userArray / Make sense? -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560 -- Before posting questions to the group please read: http://groups.google.com/group/transfer-dev/web/how-to-ask-support-questions-on-transfer Try out the new Transfer ORM Custom Google Search: http://www.google.com/cse/home?cx=002375903941309441958:2s7wbd5ocb8 You received this message because you are subscribed to the Google Groups transfer-dev group.

Re: [transfer-dev] Re: XML error on upgrade
Hi Brian and Mark, Thanks for your help, as always. While I haven't done any testing yet, the two blog entries Mark cites are very clear, and Brian's explanation here is even more complete. That's what I needed: just some documentation on what should go into the XML. Brian, I hope you can place Mark's old wiki content in GitHub. Like you, even though I no longer use Transfer for new development, I've built some rather large applications using it. And every now and then, there needs to be an update to those applications -- and I find myself saying I think I remember the syntax for that, but Thanks again to both of you.

And are there other known areas where an old config might cause errors? Tom, My apologies, this was so long ago for me I forgot it all changed. Here's what you need to change your objectCache stanza in transfer.xml to: objectCache defaultcache provider=transfer.com.cache.provider.EHCacheProvider setting name=config value=transfer/ehcache.xml / /defaultcache /objectCache For an example, this is mine with some examples of objects for which I've specified no caching:: objectCache defaultcache provider=transfer.com.cache.provider.EHCacheProvider setting value=/path/to/ehcache.xml name=config/ /defaultcache cache provider=transfer.com.cache.provider.NoCacheProvider class=package.object/ cache provider=transfer.com.cache.provider.NoCacheProvider class=package2.object2/ cache provider=transfer.com.cache.provider.NoCacheProvider class=package2.object3/ /objectCache To get started, create an ehcache.xml file with one default cache: ?xml version=1.0 encoding=UTF-8? ehcache xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; xsi:noNamespaceSchemaLocation=http://ehcache.org/ehcache.xsd; defaultCache maxElementsInMemory=1000 eternal=false timeToIdleSeconds=120 timeToLiveSeconds=900 overflowToDisk=false / /ehcache Converting from transfer.xml, timeToIdleSeconds replaces accessedminutestimeout and timeToLiveSeconds replaces maxminutespersisted. If you specify eternal=true, then the timeouts are ignored and the only thing that will cause an object to be discarded from the cache is running into the maxElementsInMemory limit. If you want to get fancier, these are just a standard ehcache configuration file so you can use the docs here for more tunable options: http://ehcache.org/documentation/user-guide/configuration For an example, here is my ehcache.xml: ?xml version=1.0 encoding=UTF-8? ehcache xsi:noNamespaceSchemaLocation=http://ehcache.org/ehcache.xsd; xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; defaultCache overflowToDisk=false eternal=true maxElementsInMemory=350/ !-- eternal for big objects -- cache overflowToDisk=false eternal=true maxElementsInMemory=750 name=event.event/ cache overflowToDisk=false eternal=true maxElementsInMemory=300 name=track.track/ !-- fine tune away from the defaults -- cache overflowToDisk=false eternal=true maxElementsInMemory=500 name=member.member/ cache overflowToDisk=false eternal=true maxElementsInMemory=1000 name=member.clubmember/ !-- short lived, eternal = false with ttl -- cache
Re: [transfer-dev] Re: Latest version of Transfer Issue
Brian, I haven't had a chance to do a diff yet, but I thought I'd let you know: after correcting my XML, I started an application on ACF 9, and got the same exact error as James. On Wed, Jul 23, 2014 at 1:58 PM, Brian G brian-goo...@vfive.com wrote: James, If you dump the argument in the working version of Transfer, what do you see? If you can dump the stack trace, we can look at the call before that and see if it's not passing in a named argument? But generally I find that these errors are unrelated to what they claim to be. I would put some logging/try/catch up a level in the stack trace to see if what you're getting is what you're expecting. E.g., in this case, Transfer has its own version of Javaloader IIRC - is it conflicting with another one on your system so JavaLoader itself is blowing up on init which manifests itself as this error? These errors inside frameworks I often find to be nearly useless so cflog/dump/try/catch becomes necessary. I unfortunately don't have a Railo setup to help with. One other quick suggestion: do a diff on the github transfer compare to the version you've been using. In reality there aren't THAT many changes. I made a couple of the ones I saw for Railo compatibility in the list but maybe I missed something that I need from your version?

Railo reports the error as: Syntax Error, Invalid Construct: CF8: Missing argument name.:When using named parameters to a function, every parameter must have a name.pThe CFML compiler was processing:ulliAn expression beginning with super.init, on line 35, column 17.This message is usually caused by a problem in the expressions structure.liA script statement beginning with super.init on line 35, column 17.liA cfscript tag beginning on line 34, column 10.liA cfscript tag beginning on line 34, column 10./ul So it’s not a Railo issue.
