Why cant two 'Flex related' fields be in the same module?

[franquero]

Hello, in a previous thread I wondered how to create a relate field associated to a dropdown item. Matthew told me about Flex relalated fileds.

I had´nt see that option, because I was customizing the module calls. As I have read in the forum:

Just to clarify, the Flex Relate option for custom fields appears only for modules that do not already have a default parent_id field.

The modules that contain parent_id fields by default are Accounts, Calls, Meetings, Notes and Tasks.

Once you create a Flex Relate field for any of the other modules, and this creates a parent type field in the fields_meta_data table, the Flex Relate option will no longer be available for new custom fields for that module.

My question is: Why cant two 'Flex related' fields be in the same module? I guess there is a logical reason for that, but iIm not able to figure it out.

Would be possible to allow a second Flex relate field with some PHP-MYSQL modifications?

Thanks in advance.

Because 'parent_id' is hardcoded in the SugarBean, causing the limitation.

Thank you for the answer.
