Volker Lamp commented on TAP5-2686:
-----------------------------------
h4. Cause analysis
Even though {{popover.js}} is present (part of Bootstrap, see
{{{}/tapestry-core/src/main/resources/META-INF/assets/tapestry5/bootstrap4/js/popover.js{}}}),
it is not set up as a module (see {{{}JavaScriptModule.java:448{}}}), for no
obvious reason, probably simply forgotten.
h4. Workaround
Users can add the missing module setup by contributing to {{ModuleManager}}
like so:
{{@Contribute(ModuleManager.class)}}
{{public static void addPopover(MappedConfiguration<String, Object> config,}}
{{ @Path("${tapestry.asset.root}/bootstrap4/js/bootstrap-util.js")}}
{{ Resource bootstrapUtil)}}
{{ Resource popover = bootstrapUtil.forFile("popover.js");}}
{{ config.add}}
{{ (}}
{{ "bootstrap/popover", new JavaScriptModuleConfiguration(popover)}}
{{ .dependsOn("bootstrap/bootstrap-util")}}
{{ .dependsOn("bootstrap/popper")}}
{{ );}}
Unfortunately, this doesn't suffice to make popovers work due to a bug in the
dependency definition (see {{popover.js:8:84}} - The '.js' in
{{bootstrap/tooltip.js}} is wrong, it should simply say {{bootstrap/tooltip}}).
The necessary change was made in Bootstrap 4.6.0. Users would have to add
Bootstrap 4.6.+ to their project manually and configure Tapestry to use it (via
the {{tapestry.bootstrap-root}} configuration symbol) instead of the built-in
Bootstrap 4.3.1.
