BC webclient crashing when adjusting width of columns on a page

JoshRing

Hi,

When I'm designing a page in Business Central OnPrem (in my case, a Purchase Order card) and I change the width of a column of the subpage, the webclient crashes. Investigating the event viewer shows the following:

Server instance: BCTest

Settings of the service tier are as followed:




Anybody have a clue?

Best regards,

Take a look at this:
https://printvis.com/tip-of-the-week-135-error-when-trying-to-personalize-pages-in-the-nav-2018-web-client/

And this
https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/devenv-page-customization-object
https://docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/devenv-running-cside-and-al-side-by-side

Personalization in the webclient is done in the form of a Page Customization Object (in the background).
This is AL, so if your setup is on premise (all C/AL) the Page Customization Object is your first AL probably without knowing about it. Therefore you need to consider generatesymbolreference when developing in the development environment, and when it is an upgraded database, generatesymbolreference has to be executed once for all objects.

This is a setting that should be activated in the servicetier too (you did this already):
Enable loading application symbol references at server startup.
