In order to optimize our AIMMS releases we are separating the WebUI component from the AIMMS engine. From AIMMS version 24.4 and onwards the WebUI will become a repository library instead of a system library. This means that WebUI will not be included by default anymore in the upcoming AIMMS releases and will have a separate release cycle.   

   

How you are going to experience it?   

   

For WebUI applications, developed in AIMMS versions older than 24.4  

 

Upon your first opening of your WebUI app, developed in a version older than AIMMS 24.4, the WebUI repository library will be downloaded and you will see this message:   

  

It is important to save the project.   

If the project has not been saved you will be prompted to do it once more upon closing or upon going to the Library manager, seeing this message:   

  

 

 In the library manager itself you will see WebUI already as a part of your Repository libraries:   

   

If you are about to publish the project on PRO in version 24.4 or later, you need to make sure you export the .aimmspack in version 24.4 or later.   

  

For new applications you are creating in AIMMS 24.4 and later  

   

Upon creating your project you will still need to choose between WebUI and WinUI:  

  

  Upon choosing WebUI, the WebUI repository library will be added to your project:  

  

  

Troubleshooting   

  • In order for the above process to happen smoothly you need to have Internet connection and access to https://library-repository.aimms.com

  • In case you upload onto the PRO portal an .aimmspack in version 24.4 or later, but exported in a version older than 24.4, you will have the following error message when you try running the application:

Hi, 

A short update: we have recently come accross different issues related to the connection between the machine whith an AIMMS project in versions 24.4+ and our repository library. These cases manifest in the following ways:

  • during WebUI model creations in AIMMS post 24.4, the creation ends up with this error message: 

...where the case creation ends up in an incomplete state, with the model missing its key folders:

...instead, containing only the MainProject folder and the AIMMS file:

  • during opening of a WebUI model saved in AIMMS 24.4+ and, say, copied from another machine, the following error message is generated:

In many of the cases, this was due to a problem with the validation of the SSL certificates of our repository library on the affected machnes. 

What solves the problem? 

Please close the project and make sure your computer updates have been recently ran. This will update your local certificates. 

If the update does not help, please, after closing the project, open https://library-repository.aimms.com:443/libs/69378F70-E906-486F-8F2C-1D606AEB9669/24.11.2.3/x64_vc143_Release.alib in MS Edge browser. This will ensure that the relevant certificates get downloaded on the machine. Then please retry. 

 

We hope this helps :)
