fanmeijian opened a new issue, #3257:
URL: https://github.com/apache/incubator-kie-tools/issues/3257
Description
When using @kie-tools/kie-editors-standalone (BPMN editor), the application
crashes with:
`RuntimeException: The ContextManager must only be set once.`
This happens because both baseJsResources and referencedJsResources include
the same .cache.js files.
As a result, the GWT runtime is initialized twice, causing duplicated
registerGWTEditorProvider calls.
Steps to reproduce
1. Build the BPMN standalone editor using @kie-tools/kie-editors-standalone.
2. Integrate it into an Angular (or other SPA) project.
3. Run the app and open a BPMN editor.
4. Observe the error in the browser console:
`RuntimeException: The ContextManager must only be set once.`
n EditorResources construction:
```
baseJsResources: bpmnLanguageData.resources
.filter((r) => r.type === "js")
.flatMap((r) => r.paths)
.map((p) => this.createResource({ path: p }, ["\\", "`", "$"])),
```
baseJsResources is currently including both .nocache.js and .cache.js files.
referencedJsResources also loads .cache.js files again.
This results in duplicate registration of GWT modules.
Workaround
Filter out .cache.js from baseJsResources:
```
.filter((r) => r.type === "js")
.flatMap((r) => r.paths)
.filter((p) => !p.includes(".cache.js")) // prevent duplication
.map((p) => this.createResource({ path: p }, ["\\", "`", "$"]))
```
Expected behavior
baseJsResources should only include .nocache.js entrypoints.
.cache.js files should be loaded only via referencedJsResources.
Environment
@kie-tools/kie-editors-standalone version: [your version here]
Browser: [Chrome/Firefox...]
Framework: Angular 16 (but reproducible elsewhere)
