MANY-YO-MANY Debug Example

Support
#1

Hello,

Do you have a many-to-many association simple (2 entities) demo example?
I have two entities: payments and transactions.
From a payment I need to choose couple of transactions. I tried with tokenList but I have the following message (even I have set the datasource):
DevelopmentException: Neither metaClass nor datasource/property is specified for the PickerField

#2

Hi,

Sure, take a look at the Cookbook pages:

#3

What about the error message?
Beside manual page, is there any specific demo example?

#4

It says: if you have defined pickerField you have to either set datasource and property or set metaClass attribute in XML (or programmatically). The same applies for TokenList usage.

#5

See also TokenList demo in Sampler: https://demo.cuba-platform.com/sampler/open?screen=lookup-tokenlist

Hi Yuriy,
Thank you for your support.

Unfortunately I have an error (see below).
[37, 53] The state field path ‘e.transaction.id’ cannot be resolved to a valid type.

Also I don’t know how can I debug this.
