i'm writing a web application that works with an external dll (activex),
the dll was written by skype developers,
the problem is that,
in a case of any event (status changing, attachment, etc..) in the client side, a delegate needs to be call on the server side.
so when i'm changing a status in the skype program, it seem that a postback really happen but there is no affect on the client side.
for example , i'm trying to change a label content by his new value from the server side (using label that runat server) but nothing change.
i succedded to make a java script interval
so when it recognize any changes
it replace the content of the label.
i preffer not to use it because the dll already support that events.
thanks in advance.
It seems that your problem is simulating a post-back to make the label change its contents. If so, this link might be helpful:

I need to update a javaEE application (still in java 1.7) that provides a SOAP web service. And I'd like to disable the TIMESTAMP_CACHE that wss4j (v2.0.2) uses to control reply attacks. It creates too many files and the OS reaches the maximum open files allowed, repeatedly. The files start to appear, one for each request that has been made and are named in the following way:
wss4j%002etimestamp%002ecache-e%0058ga%0058l%0058%004b%0057g%004ah%0050w==.data
The documentation states that the TIMESTAMP_CACHE can be changed (or so I understand):
ConfigurationConstants.ENABLE_TIMESTAMP_CACHE ("enableTimestampCache"): Whether to cache Timestamp Created Strings (these are only cached in conjunction with a message Signature). The default value is "true".
I've found many examples to change some of these ConfigurationConstants when a client application creates the Call object. See an example to change the PASSWORD_TYPE constant:
Service service = new Service();
Call call = (Call) service.createCall();
...
call.setProperty(UsernameToken.PASSWORD_TYPE, WSConstants.PASSWORD_TEXT);
call.setProperty(WSHandlerConstants.USER,"werner");
However, my application is not on the client side but on the server side and I haven't found so far the way to change the ENABLE_TIMESTAMP_CACHE constant.
Any idea?
I couldn't find a way to disable the timestamp cache. However, the wss4j behaviour described above happened to be a bug that not only resulted in lots of open files but in lots of open threads. It has already been fixed in version 2.0.9. Upgrading to the "newer" version did the trick.
You can find here the discussion in full that drove to the bug discovery and here the fix in wss4j's jira
I use SAP standard library: Inbox.
in library class S3.controller by tap on attachments icon is onTabSelect event executed, witch makes
this.fnDelegateAttachmentsCreation();
this.fnFetchDataOnTabSelect("Attachments");
this.fnHandleAttachmentsCountText("Attachments");
this.fnHandleNoTextCreation("Attachments");
break;
fnFetchDataOnTabSelect makes an asynchronous call. During this call is fnHandleAttachmentsCountText already executed, so the update of attachments count occurs before the request for attachments is ready. As far the request for attachments is ready, there is no update for title executed.
On screenshot is AttachmentCountText „Attachnents (1/1)“, that comes from previously selected item.
It should be „Attachements (2/2)".
Also if response comes too quick, then view changes to loading view after it received the answer from request.
If list of attachments was updated from request callback, then it should not be updated second time.
Here it seems, that there is something on loading, but request is already finished.
How could be Inbox extended, to update the attachment header and content after request is ready?
used SAPUI5-Version: 1.71.4
You are using the standard bsp-application ca_fiori_inbox?
You didn't create an extension project of the application ca_fiori_inbox with custom coding?
If that's the case, it's a bug in an standard application delivered by the SAP. SAP releases so called notes to fix bugs in their standard applications.
You can import notes in your system via the transaction SNOTE. May ask a SAP Basis Administrator from your company for help.
The following notes exactly describe your problem
2873960
2823664
2916255
2901520
If you already extended the SAP standard application(MyInbox) without using ExtensionPoints codechanges in the standard application will not affect your custom extension.
When overriding a controller method, any functionality that was previously provided by it is no longer available. Likewise, any future changes made to the original controller method implementation will not be reflected in the custom controller.
In this case you could still implement the note and check the changes in the standard controller vs. your custom controller on your system and change the respective lines in your custom coding.
Don't fix SAP coding. Report it and get a fix.
The Note 2873960 corrects coding in an abap class, not in the bsp-application(ca_fiori_inbox). So definitly import the note and check if it's fixing your problem.
I actually do not know, how the app works, but I want to give it a try.
Since it is an asynchronous function, you can always also wait for the function until it is done. So in your case, you could try to set an await keyword in front of the function.
await fnFetchDataOnTabSelect("Attachments");
This will now wait on this position until it has finished the function call before it will call the next functions. In addition to that you also need to set the upper function onTabSelect to async. So in the end it should look something like this.
onTabSelect: async function() {
// ...
this.fnDelegateAttachmentsCreation();
await this.fnFetchDataOnTabSelect("Attachments");
this.fnHandleAttachmentsCountText("Attachments");
this.fnHandleNoTextCreation("Attachments");
// ...
}
Although the Web IDE maybe shows you errors, it does work, since it is an official JavaScript API.
My question is very basic on one hand but on the other hand the general situation is more complex, plus I cannot really get any working sample.
I'm developing/maintaing a web-application which is currently in transition from GWT code base into Ember.js.
Most of the newer code already relies on Ember.js and I think it's really awesome.
The problem is we cannot use Ember Router as all the request are being handled by the GWT.
In order to enabled the application run in this unusual configuration we have special JavaScript files that create our Ember main objects (Controllers & Models) for us.
As you can imagine navigation between tabs is cumbersome and is handled by GWT who creates Ember objects when needed. We are in transit toward a brave new world Ember Router and all.
But in the meantime, this is the problem I'm facing right now.
The user clicks a link which opens a page that contains some Ember based table.
The data is retrieved form the server using some Ajax code. Upon success it spawns a forEach loop which tries to pushObject all the received date into our Ember based components.
My problem happens when the user quickly switches between tabs. In this case the first list of object has not finished rendering yet and suddenly there's a new set of objects to handle. This causes Ember to throw errors like:
"Uncaught Error: Cannot perform operations on a Metamorph that is not in the DOM. "
and
"Uncaught NotFoundError: An attempt was made to reference a Node in a context where it does not exist."
Is it possible to prevent the loop from trying to render?
I've tried checking if the controller in question is already inDOM and it is, is there a way to notify Ember this object is no longer valid?
Sorry for a lengthy question and lack of running sample.
I'd probably modify the switch tab code to only execute afterRender has completed, that way you aren't mucking with ember objects while they are being used.
Ember.run.scheduleOnce('afterRender', this, function(){
// call GWT switch tab routine
});
Thank you Daniel and Márcio Rodrigues Correa Júnior. eventually what I did is to add a patch that would check the current context of the application (in my case the currently selected tab). If upon receiving the AJAX response the application is in the correct context (meaning the user haven't change the tab) go on. Otherwise just ignore the response and do not try to render it.
Now it seems to be working
I am developing an app using Grails and GWT for a client side.
I want to use the same date format both on the client side and on the server side (preferably defined in one file).
So far i've understood that Grails got it's own mechanism for internationalization (grails-app/i18n). I know i can access these messages from any server code using app context.
I can also access any resource file inside web-app directory.
For the client side, i can use ConstantsWithLookup interface and GWT.Create(...) to get an instance of it.
But, i still haven't found good solution to integrate these two together, so i have date format defined in one place. Any ideas or tips?
Thanks,
Sergey
After digging into Grails more, i came to a solution.
I've put constant into .properties file under grails-app/i18n.
Then, i hook to eventCompileEnd and i copy resources from grails-app/i18n to specific package in target\generated-sources.
After this step is completed, i generate google I18N interfaces using copied property files.
I've put this functionality to separate plugin.
_Events.groovy:
includeTargets << new File("${myPluginDir}/scripts/_MyInternal.groovy")
eventCompileEnd = {
internalCopyMessageResources();
}
eventCopyMessageResourcesEnd = {
generateI18NInterface();
}
Now it is possible to access localized data from server side and from client side.
I have an application that started life as an MVC (1.0) app in Visual Studio 2008 Sp1 with a bunch of Silverlight 3 projects as part of the site. Nothing fancy at all. Using Ninject for dependency injection (first version 2 beta, now the released version 2 with the MVC extensions).
With the release of .Net 4.0, VS2010, MVC2 etc., we decided to move the application to the newest platform. The conversion wizard in VS2010 apparently took care of everything, with one exception - it didn't change references to mvc1 to now point to mvc2, so I had to do that manually. Of course, this makes me think about other MVC2 things that could be missing from my app, that would be there if I did File -> New Project... But that is not the focus of this question.
When I deploy this application to the IIS 7.5 server (running on Win2008 R2 x64), the application as such works. However, images, scripts and other static content doesn't seem to exist. Of course they are there on disk on the server, but they don't show up in the client web browser.
I am fairly new to IIS, so the only trick I knew is to try to open the web page in a browser on the server, as that could give me more information. And here, finally, we meet our enemy. If I try to go directly to the URL of one of the images (http://server/Content/someimage.jpg for instance), I get the following error in the browser:
The IControllerFactory 'Ninject.Web.Mvc.NinjectControllerFactory' did not return a controller for a controller named 'Content'.
Aha. The web server tries to feed this request to MVC, who with its' default routing setup assumes Content to be a controller, and fails.
How can I get it to treat Content/ and Scripts/ (among others) as non-controllers and just pass through the static content? This of course works with Cassini on my developer machine, but as soon as I deploy, this problem hits.
I am using the last version of Ninject MVC 2 where the IoC tool should pass missing controllers to the base controller factory, but this has apparently not helped. I have also tried to add ignore routes for Content etc., but this apparently has no effect either. I am not even sure I am addressing the problem on the right level.
Does anyone know where to look to get this app going? I have full control of the web server so I can more or less do whatever I want to it, as long as it starts working.
Thanks!
I had a similar problem with StructureMap and favorite.ico what I ended up doing was to add a route to ignore that path.
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("favicon.ico");
Keep in mind that I have absolutely no idea really but another thing that changed is the need for Default.aspx, also if you have any custom pages those would need to mapped. That's the only two problems I had with routing.
routes.RouteExistingFiles = false;
EDIT: I meant that the RouteExistingFiles should be false otherwise I get that exception in MVC2 :)
Turns out this was caused by some account settings - I was unaware of the IIS AppPool\sitename account automatically being created by IIS in Win2008 R2 server. After trying "everything", I came across this information, gave the proper rights, and stuff magically started working.
Pretty hard thing to debug, especially for someone (me) with very limited IIS experience.
