Date Picker field's calendar widget intermittently displays without any days

[dpkhmhs]

AEM 6.5, SPA, Angular 9, Bootstrap 4

AEM Forms packages:

adobe-aemfd-linux-pkg-6.0.1120.zip

adobe-aemfd-compat-pkg-2.0.48.zip

Date Picker field's calendar widget intermittently displays without any days (see image above).  It works most of the time, but we haven't been able to come up with steps to reproduce the blank popup.  We've seen the behavior on different Date Picker fields on different Adaptive Forms.

1. Has anybody seen this behavior before?
2. Do you have steps to reproduce the issue?
3. Were you able to fix the issue or at least any hints for what to look for?

@dpkhmhsAre you using foundation-based forms or core component-based forms? We've addressed many similar issues to the one you reported with the date picker core component. You can check the component here: https://github.com/adobe/aem-core-forms-components/tree/release/650/ui.af.apps/src/main/content/jcr_...

I'm using whatever form components are installed with the AEM Forms install packages.  The component group for all the form components I'm using is "Adaptive Form".  The sling:resourceType is "fd/af/components/guidedatepicker".  I've always thought I'm using the core components but is there a simple way to know for sure?

Based on the screenshots you shared, it appears you're using foundation components to build the adaptive form. We recommend using the forms core components available through the AEM project archetype for creating adaptive forms.

Could you please switch to using the core components for this use case? We've resolved similar issues in the past using them.

[dpkhmhs]

We're at the end of our project so switching to forms core components is probably not going to be feasible.  We started with the AEM project archetype back in 2021.  At the time, we weren't going to use AEM Forms so it wasn't installed via the archetype.  Once AEM Forms were installed from standalone packages, we just started to use whatever forms components came with that.

How would I know if I had the forms core components installed but just aren't using them?  I do see a bunch of other component groups that have form components in them, but they are basic components and only about 6 components total.

Could you please log a ticket through the support channel to have this addressed in the foundation components? Also, kindly include the steps to reproduce the issue.

User has been asked to log a ticket through the support channel to have this addressed in the foundation component. If you are starting a new project, it is recommended to use Core Components.
