Hi,

In several posts people stated that in a mobile application all screens should be in one eSpace. No one however mentioned the reason for this.

From a maintenance perspective I'd like to split my UI in several eSpaces (like I do in a web application). I've created a sample and it worked. I have a main screen which is the module from the orchestration layer, which calls a screen from another module as an "External Site". As long as the user providers of both screens are the same no problem arises from an authorization perspective.
The application also works fine, when deployed as an apk on an Android device.

Does anyone know the problems which may arise from splitting a mobile application in several UI eSpaces?

Your help/thoughts are apreciated,

Matthieu de Graaf

In a project, before the screens are split, but there is performance penalty, so all are put in one module. I think this is performance issue.

regards

This could be an issue. I noticed a perfomance difference between the 2 solutions (calling screens from another eSpace and calling screens with webblocks from another eSpace).

regards,

Matthieu

Hi Daniel, I already a working version that allows validating tokens with x509 certificates, and even has support for JWKS. Let me do another round of testing and I publish a new version in the Forge.

Hi Vikhyat,

I'm using this oap file. Try also to increase the Server Request Timeout from this module in the interface tab.

Hi Cátia,

I used the file attached by you but when I am viewing Movies data, I'm getting the error as attached in the picture.

I clicked the publish button. Still, I'm not able to access the data of Movie entity. I'm new to Outsystems, so can you tell me where can I change the Server Request Timeout as I'm not able to find it.

Regards

That's the trade off: monolithic is faster than modular, but modular is more maintainable.

Vikhyat, This OML has reference problem. Please send the complete application

Hello Pradeep,

I'm new to Outsystems, I don't understand how to send the complete application. But you can use the movies data from the Movies assignments or from the OAP file send by Catia in the previous reply. Thanks for checking it out.

The reason, I think, is exactly in the way Mobile is different from Web.

Mobile is a "One Page" application.

Everything is in a single page, and the different "views" are created on the fly using JavaScript.
I think (not sure) if you call an "external page" (a page in another module), you have to "reconstruct" everything again, than the perfomance penalty, because it is (again, I think), a different page.

Now imagine the impact of you going forth and back to different pages in different modules...

Cheers.

Hi guys,

Curious about this. What kind of performance difference have you found using blocks? Slower transitions between screens? Slower data loading? Slower splash screen?

Hi Vikhyat,

I am also new to Outsystems so we are in the same package!

Did you try to upload the file attached following the steps from assignment 1?

After that you open the MoviesData module, change the Server Request Timeout in the properties area.

Hi ,

I am looking at training material and practicing Outsystems for mobile app development. I am doing a POC with sample UI and consuming Rest services. I have already implemented list to show countries from service. But now i want to show list from local storage instead directly from response. I want to store the response countrylist object into local storage and fetch the list object from storage using aggrigates and display in List UI.

can any one help me to understand the process to implement the same. Please find attached flow diagram which i have implemented to display directly from service. How can i modify it to display from Local storage.

Hi Cátia,

I increased the Server Request Timeout to 60 but still, I'm getting the same error. Could you able to see the movies data in the data tab? I can see the cinema's data but I'm not able to see the movie's data. Please check attached.

Hi, i am wondering if someone can help me with an issue in Safari:

Whilst trying to navigate to a certain page, the js scripts are throwing the following errors and preventing functionality on the page. This is only happening in safari, not in any other browser.

The following errors are:

SyntaxError: Parse error

TypeError: Result of expression '$(elementID).inputmask' [undefined] is not a function

I am using the latest version of the Custom Masks module from the forge.

Has anyone had any issues with the custom masks error in safari like this? If so, how did you get around it?

Cheers

Jake

Hi,

I was wondering if it makes sense to normalize your database structure on OutSystems? I normalized one database table and as a result I now have 12 different database tables, which are, of course, linked to each other via foreign keys.

I notice two cons:

1. Increased complexity (data handling, esp. when working with an existing sometimes inconsistent database) and therefore increased time to create the app

2. Increased costs: Before: 1 Table online + offline = 2 AO, After: 12 Tables online + offline = 24 AOs + increased labour costs

Pros:

1. A nice database strucure

Weighing up the pros and cons, what do you think would be the way to go here?

Thanks and best regards

Sebastian
