Re: [Wonder-disc] Is there an equivalent for the ?key="value" syntax but for ognl inline bindings

[Mike Schrag]

How about inserting the closing "]" as soon as one types the opening  
"[" in the context of a binding value?
Valid point -- totally could do that ... Trying to think if there's a  
case where this would get confused, but it seems pretty  
straightforward.  Patches welcome :)

Re: [Wonder-disc] [ANN] New Screencast

[Mike Schrag]

Well, it's SUPPOSED to be the case that it only generates a closing  
tag if the WO's API file says it's a component content, but either the  
API files are wrong (very possible -- most people are lazy with API  
files) or there's a bug in that (also very possible because I'm lazy  
with correctness :) ).

sends corporate "policing" web page filters through the roof, for the

Yep, I noticed that, that's why I thought that maybe woognl offered

 The problem is that configurable inline binding
syntaxes makes things a complete mess.  It means you can't mix
frameworks because each framework may choose its own syntax.  So I'm
sort of hesitant to add a configurable option provide a custom prefix/
suffix (like 5.4 does) because it seems like it's a long term
disaster, and I can't wholesale switch to "[xxx]" in Wonder (one
because I hate the syntax, two because we have backwards compatibility
to consider).  It would have been nice for 5.4 to have adopted the $
syntax that we had been using, but things didn't turn out that way.
The only way to properly deal with it is by setting the syntax you use
in the framework Info.plist or something, but that seems like super
overkill.


Agreed.

Hello,

Subject line says it all.

Btw I'm using WO 5.3.x NOT WO 5.4.x for which apparently such syntax  
exists.


On a related note is it possible to change the market ( currently "$")

I just talked to my buddy and he notes that there is some db access in  
this component after all.


Six years ago, our team were all WONovices, and one of our colleagues  
thought he'd 'improve' EOF by adding a smart layer over it.  EOF is  
more than plenty smart all by itself and I expect this other stuff and  
EOF are operating at cross-purposes [for example, as you suggest, it  
may be defeating EOF's faulting strategy and slowing everything  
down].  The db has grown over time (university phone records) and any  
db inefficiency is probably going up faster than linearly.  I've been  
trying to eliminate his code, but it got knotted around a lot of stuff  
in a rather non object oriented manner.


I must admit it wasn't till I saw just how fast the parser was ripping  
through my time-wasting HTML that I started to realize there had to be  
more going on than just rendering effort.  A million  per  
second caught my attention!

how to thread a really computationally intensive page ?

[Gavin Eadie]

My colleague has an application [a rather old application written as  
we learned WebObjects with much that is embarrassing in the cruel  
light of our current skills] which occasionally is called on to  
display a report that can take considerable computation as it grinds  
through various nested WORepetitions -- in a worst case, about 45  
seconds of elapsed time.  The data for the report is already in memory  
so no EO operations are happening during this, just lots of rattling  
round and round in WOComponents.


We're looking at various options -- improve the Java code, generate  
the reports off-line as static HTML, etc.


The option I'm looking at is to render this report under the operation  
of a WOLongResponse.  I've not used this class before, so I looked at  
Apple's example and wrote a trivial example of my own to get a sense  
of how it operates.  What I'm stuck on though is whether it is  
possible to generate a web page during a WOLongResponse with something  
like:



public class Slow extends WOLongResponsePage {

   public Slow(WOContext context) {
  super(context);
   }

   @Override
   public Object performAction() {
  WOComponentcalcPage = pageWithName(Calc.class.getName());
  WOContext  calcCntx = calcPage.context();
  return calcPage.generateResponse().contentString();   // may  
take a long time

   }

Frameworks.  You want frameworks.  Frameworks are WebObjects (and,  
well, OS X's) way of sharing things between applications.  Put the  
models and the related code in a framework and use the framework in  
the application.  I _never_ _ever_ put a model in an application.



However, it transpires that both models have a couple of entity  
names in common.


Are they the same entity (same database, same table)?  If so, create a  
framework and model to hold the common entities.  Use this framework  
in the frameworks holding the models with the other entities.  Include  
all three frameworks in your application.


If they are not the same entity but just happen to have the same name,  
then you need to rename one of them.



 I can understand why this would cause a problem, what I need to  
know is if there is a way around this without having to completely  
rename the entities in one of the models.


The other strange thing is that it tells me there is a name conflict  
between the EOPrototypes entity in each model, but I don't think  
there is any other way to name this entity, correct?



You probably guessed this already, but "framework".  The prototypes go  
into a model by themselves and this framework is included in  
(referenced in) the frameworks that have models and in the application.


Thus
Application
-> Prototypes framework
-> Common entities framework
-> Other EO framework 1
-> Other EO framework 2

I think you have to use a prefix or similar mechanism. Like DDUser,
DDGroups, FFUser, etc... This should only be needed on the entity names, we
usually organize the java classes in packages instead of using prefixes in
java names.

The prototypes should probably be factored in to a 3rd model.

Re: Multiple EOModels

[Simon McLean]

from the EOModelGroup docs:

The default model group contains all models for an application, as  
well as any frameworks the application references. It is automatically  
created on demand. The entity name space among all of these models is  
global; consequently, the same entity name shouldn't appear in any two  
of the models. All cross-model information is represented in the  
models by entity name only. Binding the entity name to an actual  
entity is done at run-time within the EOModelGroup.


so rather than using the default group you could programatically  
create a model group for each model. i believe you can then access  
each model from within your app, but you can't create relationships  
between the models because they are in different groups. this of  
course presumes you have the common entities in different packages. if  
you are using the default package, well, you shouldn't be :-)


Note i'm no expert on this - i've little experience with multiple  
models in one app - but i'm sure someone will correct me if i'm  
talking rubbish :-)

Any way to "know" a "No instance available" has been answered to client?

[Fabrice Pipart]

Hi all !

I have a Cocoa application calling a WO web service method.
If the server is over loaded, it answers "No instance available" to  
the Cocoa app after (by default) 30s.
I want to know if the method has been actually executed on the server,  
therefore my web service returns true or false.

If I receive the no instance message, I consider the call failed.
But actually the web service call gets executed even after the no  
instance message.


Is there any way to "know" that "No instance available" has been  
answered to the client?

Re: WebObjects 5.4(.1) and https

[Mr. Pierre Frisch]

With WO 5.4.x WOContext has gained a few method to correctly manage  
the secure transport.


/**
 * Return true if the context is in secure mode.
 *
 * @return true if in secure mode
 * @since 5.4
 */
public boolean secureMode()

/**
 * Puts the context in secure mode.
 *
 * @param value
 */
public void setSecureMode(boolean value)

WOContext should also correctly manage the complete URLs. If the  
secure mode is turned on and the request was not made on secure  
transport then the URL will be complete.


Cheers

Someone has the same experience than I when using redirection to  
change from http to https ?

Here is the message I've sent yesterday to the Project Wonder list ...

In the application I'm currently working on, I sometimes have to  
turn to HTTPS (decision made at runtime) using the following code in  
Session.appendToResponse :


public void appendToResponse(WOResponse aResponse, WOContext  
aContext) {

// Shall we ask for HTTPS or HTTP (or leave the transport as it is).
boolean tmpRequestIsSecure =  
RequestAdditions.isSecure(aContext.request());

super.appendToResponse(aResponse, aContext);
if ((requireSecure && !tmpRequestIsSecure) || (requireNotSecure  
&& tmpRequestIsSecure)) {

// We have to redirect towards the same page, but different schema
String schema = (requireSecure) ? "https" : "http";
	String redirectToURL = schema + "://" +  
RequestAdditions.hostName(aContext.request()) +  
aContext.componentActionURL();


aResponse.setStatus(302);
aResponse.setHeader(redirectToURL, "Location");
	NSLog.debug.appendln("Switching schema to : " + schema + ".  
Redirecting to the URL '" + redirectToURL + "'.");

}
}

Till now I was developing using WebObjects 5.3.? (+ Wonder), and  
this was all working nicely. In particular, whatever this redirect  
would do the URL generated by WebObjects in the html sources would  
be absolute but would NOT contain the schema and host name (in other  
words they'd start like '/cgi-bin/WebObjects/Incident.woa/')


I have just upgraded to Leopard, and hence WebObjects 5.4.1 (+  
Wonder).
Now the redirect still works (when enforcing 'https' usage), but  
upon such a redirection all the URL generated in the page are now  
'complete' URL, that is they contain the schema, the hostname and  
then the rest (eg. 'http://foo.local/cgi-bin/WebObjects/Incident.woa/') 
. In particular, when turning to 'https' all the generated URLs are  
now EXPLICITLY NON secured http ('http'). Still if there is no- 
redirection the generated URLs are the same as before (like the one  
generated by WO 5.3, non-complete URL, eg. '/cgi-bin/WebObjects/ 
Incident.woa/').


I have tried to check the value of  
aContext.doesGenerateCompleteURLs() (which in all cases is FALSE,  
which to me means that all generated URL should be absolute path  
without schema and hostname).


I realise that the former https bug of WebObjects 5.3 is now fixed  
and it might be normal that my code is not working anymore, but I  
could not find how I should change my code to conform to the new WO  
version?


Any help or hint is very welcome !

Re: SQL Query from EOFetchspecification

Hey Rohit,

1. Don't use qualifierWithQualifierFormat, build the EOKey- and  
EOAndQualifier yourself.

2. Do you want the SQL as a String? Sorry, never need that, so no idea.
3. Do you want to execute the Query? Use EOEditingContexts

Re: FW: Model wierdness

[Stefan Klein]

Hi,

is there any flattend attribute in project? In that case you will get 
'duplicates' through the toMany relationships.

If not, try spec.setUsesDistinct(true).

To trace in the generated SQL statements, go to Open Run Diolag in 
Eclipse, select your application and activate 
NSLog.DebugGroupDatabaseAccess and NSLog.DebugGroupEnterpriseObject. Now 
you can follow the statement send to the database.

List,

I have a weird model issue.

When I load the database in my application some entities show up double.

For example, I load a projectDisplayGroup and I only want to see 
projects that are not complete.


In my (oh so appropriately named) viewProjects class constructor, I do 
the following:


 


Integer status = new Integer(2);

NSMutableArray args = new NSMutableArray();

args.addObject(status);

EOEditingContext ec= session().defaultEditingContext();

EOQualifier qual = EOQualifier.qualifierWithQualifierFormat(“status !=

EOFetchSpecification spec = new EOFetchSpecification(“Project”, qual, 
null);


spec.setRefreshesRefetchedObjects(true);

EODatabaseDataSource ds = 
(EODatabaseDataSource)projectDisplayGroup.dataSource();


ds.setFetchSpecification(spec);

projectDisplayGroup.fetch();

 

My database does not have any duplicates in it, but my viewProjects 
page shows a duplicate entries as can be seen by the screen shots I’ve 
attached.


Anybody have any ideas on what could be causing the problem?

Thank you in advance,
