Lookup single-select / multi-select fields are triggered in the field.edit.before stage, before the object picker is opened.

• Intercept add actions at this stage
• Process the input parameters of the object picker
• Replace the object picker

Parameters

Parameter	Description	Type
fieldName	api_name of the field that triggered the event	String
objApiName	api_name of the object that triggered the event	String
dataIndex	dataIndex of the record that triggered the event, used for detail-object data	String
selectObjectParams	Parameters that will be used to open the object picker. These can be modified in the plugin	Object

Key properties of selectObjectParams

Parameter	Description	Type
isSingle	true for single-select, false for multi-select	Boolean
filters	Filter conditions	Array
wheres	Filter conditions	Array
disableAdd	true disables creating new records from the picker list	Boolean

Return Value

Parameter	Description	Type
consumed	true means subsequent logic will not continue	Boolean
selectObjectParams	Parameters that will be used to open the object picker	Object
selectObject	Object-selection method (async). The plugin handles the selection logic and returns the selected data. Multi-select is supported	Function

Code Example

Filter available selectable data:

{
    event: "field.edit.before",
    functional: function (pluginExecResult, options) {
      	let {selectObjectParams}=options;
      	selectObjectParams.filters = (selectObjectParams.filters||[]).push({
          field_name:"name",
          field_values:["Red"],
          operator: "LIKE"
        })
      	return {selectObjectParams}
    }
}

Implement the selection control in the plugin and replace the default picker:

{
    event: "field.edit.before",
    functional: function (pluginExecResult, options) {
      	let selectObject = async function(params){
          let objectDataList=[]
          return {objectDataList}
        }
      	return {selectObject}
    }
}

Notes

• Calling dataUpdater to update data in this event is not suitable.
