Related List Edit SlushBucket Behavior

[Chakravarti]

Hi,

I have tables A, B and A2B for m2m mapping in a  scoped application.

When I open record of A in platform UI, I am showing related list for A2B. I am trying to show Edit button which will open slush bucket behaviour. 

Edit button was not shown by default on A2B related list. When I set 'Reference floats' to true on column A in A2B table, Edit button shown is shown.

When I click Edit button it is opening slush bucket. Left side of slush bucket is empty.

I want left side to be populated will all values of table B. Is it feasible? I think it is very common scenario, and definitely there will be solution. 

Please provide your inputs.

Thanks,

Chakri.

Can I insert records in to sys_collection.list to get desired behaviour?

Hi,

After declaring m2m relation on the sys_m2m table, I see some entries in left side of slush bucket. But their name is not displayed. It is showing as empty string. 

Please suggest.

Hi Chakravarti,

Please try and reply to my previous reply to keep a thread going.

regarding sys_collection, this is the legacy m2m definition table and shouldn't be used for new declarations.

For the slush bucket, you'll need to define a display value for the related table

Thank you.

In my example, tables are A, B, and A2B

I created two relations in sys_m2m table.

1. A2B as parent table and B as child table

2. A2B as parent table and A as child table

I opened record of table A. I see related List for A2B table. 

Do I need to define display value for table B?
