simple code

wails-project.zip

App.d.ts use

func arrayifyValue(valueArray string, valueType string) string {
	valueType = strings.ReplaceAll(valueType, "*", "")
	gidx := strings.IndexRune(valueType, '[')
	if gidx > 0 { // its a generic type
		rem := strings.SplitN(valueType, "[", 2)
		valueType = rem[0] + "_" + jsVariableUnsafeChars.ReplaceAllLiteralString(rem[1], "_")
	}

	if len(valueArray) == 0 {
		return valueType
	}

	return "Array<" + valueType + ">"
}

modules.ts use

func nameTypeOf(typeOf reflect.Type) string {
	tname := typeOf.Name()
	gidx := strings.IndexRune(tname, '[')
	if gidx > 0 { // its a generic type
		rem := strings.SplitN(tname, "[", 2)
		tname = rem[0] + "_" + jsVariableUnsafeChars.ReplaceAllLiteralString(rem[1], "_")
	}
	return tname
}

I think nameTypeOf is missing tname = strings.ReplaceAll(tname, "*", "")

Triage notes:

• Classification: Bug (v3, Typescript) — nameTypeOf() in modules.ts binding generator is missing strings.ReplaceAll(tname, "*", "") which arrayifyValue() in App.d.ts already does, causing inconsistent type names for pointer types in generic bindings.
• Labels applied: Bug ✓ (already), Typescript ✓, v3 ✓ (added)
• Action: Comment-only — the reporter has already identified the root cause with a specific code fix. Good candidate for community contribution.
