This hook is called before the detail page processes data. It can process or modify detail data before object detail rendering.

Parameters

functional registers the hook callback. The host passes the following parameters:

Parameter	Description	Type	Allowed Values	Default
context	Event context containing common parameters	Object	--	--
plugin	Current plugin runtime information; business logic normally does not need it	Object	--	--
context.data	Complete interface data before detail page parsing	Object	--	--

context.data

Parameter	Description	Type	Default
data	Raw field data for the current record	Object	--
describe	Raw describe for the current object	Object	--
objectDescribeExt	Extended object describe; may be absent when the interface does not return it	Object | undefined	--
layout	Raw detail layout and component configuration	Object	--

context.data may also contain approval, process, or business extension fields. Preserve original data that does not need to change.

Return Value

The hook may return Object or Promise<Object>. The returned object is shallow-merged into the top level of context.data before detail parsing. When the hook returns nothing, the original data is used.

A direct throw from a synchronous callback is caught and logged by the PWC adapter, and the host proceeds as though the hook returned nothing. The current Detail wrapper does not handle a rejected Promise, including an exception thrown from an async callback, so the detail parsing flow may remain pending. Catch and report asynchronous failures inside the hook, then resolve a usable result.

Parameter	Description	Type	Allowed Values	Default
data	Overrides raw field data; preserve other fields when changing one field	Object	--	--
describe	Overrides the raw object describe	Object	--	--
objectDescribeExt	Overrides the extended object describe	Object	--	--
layout	Overrides raw layout and component configuration	Object	--	--
miniSide	Whether the right-side area is collapsed by default; omission uses the local user cache	Boolean	--	--
tabsMemoryTab	Whether tabs remember the last selection	Boolean	--	true

Basic Examples

Modify Record Data

export default class Plugin {
    apply() {
        return [{
            event: 'detail.parse.before',
            functional: this.parseBefore.bind(this)
        }];
    }
    parseBefore(context, plugin) {
        return Promise.resolve({
            data: {
                ...context.data.data,
                name: 'Name set by the plugin'
            }
        });
    }
}

Disable Tab Selection Memory

return Promise.resolve({
    tabsMemoryTab: false
});

Expand the Right-side Area by Default

return Promise.resolve({
    miniSide: false
});

Notes

1. Refreshing the detail page also triggers this hook.
