Multiple selection in the listgrid saves with brackets ([])

[yohyoung]

Hi, I am using SmartClient V11.0 Enterprise Edition build 2016-12-25

I have tested multiple = true in the listGrid and I found the values selected are stored(saved in the database) with brackets. And when I try select again, the selections do not applied again(not checked).
Furthermore, everytime I click the field and press enter key, the bracket keeps adding like [[[[Asia,Europe]]]]

Here is example "ListGrid> Editing > data validation" I have simulated.
-----------------------------------------------------------------------------------------
isc.ListGrid.create({
ID: "countryList",
width:550, height:224, alternateRecordStyles:true,
dataSource: countryDS,
fields:[
{name:"countryCode", title:"Flag", width:40, type:"image", imageURLPrefix:"flags/16/", imageURLSuffix:".png", canEdit:false},
{name:"countryName"},
{name:"continent", multiple:true}, // <------------------------------------------------------ put multiple:true
{name:"member_g8"},
{name:"population",
validators:[
{type:"integerRange", min:1}
]
},
{name:"independence"}
],
autoFetchData: true,
canEdit: true,
editEvent: "click"
})

See dataSourceField.multipleStorage.

Also, a further note: your test case is invalid because you've put multiple:true on a widget when the DataSource field continues to not be declared multiple. The grid correctly attempts to store an Array, and the server correctly flattens this into a string because that's how the field is declared, hence your result.

I really appreciate your help. I fixed as below,

In ds, I added
<field name="companies" type="ntext" multiple="true" multipleStorage="json"></field>

ofcause in Listgrid definiation, I have multiple:true

It works fantastic!!!. thanks,
