@shravanthprasad, we have a test collateral for this use case. You can review the test specification at https://github.com/adobe/aem-core-forms-components/blob/master/ui.tests/test-module/specs/customFunctionTest.spec.js and the corresponding form collateral at https://github.com/adobe/aem-core-forms-components/blob/master/it/content/src/main/content/jcr_root/content/forms/af/core-components-it/samples/af2-custom-function/basic/.content.xml, along with the client library available at https://github.com/adobe/aem-core-forms-components/tree/master/it/apps/src/main/content/jcr_root/apps/forms-core-components-it/clientlibs/clientlib-it-custom-function

@shravanthprasad, can you attempt the use case on version 6.5.19? According to version metrics, (https://github.com/adobe/aem-core-forms-components/blob/release/650/VERSIONS.md) support for 1.1.32 is only available after 6.5.18.

Hi @rismehta - Thanks for your response. We are on AEM 6.5.17 currently and upgrade to 6.5.19 is planned in second half of 2024. Downgraded to version 1.1.26 and I still see the same issue.
Upon further analysis, I see the servlet(AdaptiveFormCustomFunctionProviderServlet) is not present in bundle(com.adobe.aem.com.adobe.aem.forms.af.rest) which handles the custom function request http://localhost:4502/adobe/forms/af/customfunctions/L2NvbnRlbnQvZm9ybXMvYWYvbm93LWFlbS1mb3Jtcy9yaXNlLXVw
The bundle version is 0.0.90 in AEM 6.5.17

@rismehta - We were trying to set value of dropdown component(options) using custom functions in rule editor. But since custom functions is a blocker on AEM 6.5.17 because of above issue, do you have any workaround/suggestion for implementing dropdown options from clientside?

Custom function support was introduced in a subsequent update. To utilize this feature, you may need to either upgrade or submit a hotfix request through the support channel.

We've created a new release, built upon version 6.5.17, for the custom function. You can find it at https://github.com/adobe/aem-core-forms-components/releases/tag/core-forms-components-reactor-1.1.27-wcmB008. This release incorporates a workaround involving the hardcoding of the function name.
