Hi,

I have this below editor screen which have a lookup field, when I pick multiple values from lookup field , it will only apply it for first selected value. How can I hold all the values which I select.

Hi,

Unfortunately, LookupPickerField is a single select component and does not support multiple selection. You could use TokenList instead.

Thanks for TokenList suggestion. But I have implemented like it mentioned in the topic and its giving me below exception:

You can find tokenlist on cuba sampler.

Hi,

I have gone through this above topic, but for me looking up records as a ‘entity’ and holding it is the issue.

#7

Hello, @saurabh60292

The TokenList component should be bound with the property that is represented by some collection: List or Set. Please check whether the subID property is a collection or not.

Daniil.

Hi @tsarev

As you can see SubID is entity type. So in this case can’t we use TokenList?

#9

No, you cannot bound TokenList with this property. And of course you cannot hold multiple values in this property.

#10

Ok, So in this case how can I edit some records for multiple users if I want. because I think this can be a common requirement in some case using Cuba. Any suggestions?
I had attached sample project in above post if required.

#11

So, if you want to store multiple values you have to use some collection as a type for a property.

In your case the subID property should have the List<UnderwritersIns> or Set<UnderwritersIns> type. And then you will be able to use TokenList with this property.
