Anything for maintainers to be made aware of

• drag drop a table for link creation; don't save, cancel instead. add menu if open now displays link as default. should be single line text
• has-many link creation succeeds but doesn't create any column
• On click over cell outside link, change cell to select mode
• Link column edit menu, display column type; if we do not wish to allow user to change type, we can still display column type but disable modifications to it
• Discuss if singular/plural configuration required.
• Discuss if we need to display both LTAR & Link field for the same relation in Form view?
• Delete on a cell should unlink all
• Filters are not supported yet. IMO, we can treat these as rolled up numbers & allow filters/sort that are applicable to numbers
• Default fall back names when configuration for singular & plural is cleared - can be link/links instead of item/items
• Shared view error on accessing link Failed to load children list: Cannot read properties of undefined (reading 'type')
• Display name configuration appears twice; good to have it only under Show more?

• kanban, link text display - align to the left as other cells do

[dstala]

• Let's specify default values in the text box (OR) as placeholders
  
• Remove LinkToAnotherRecord from add new column data type list
• Change link field name in adjacent table from tablex to <Adjacent table name> List; similar to the default value that we have for parent table link field
• Self table link, create only one field (parent field)
• On Link field, double click (OR) Click enter should open child list modal
• Default column name - should it be Sheet-1 List OR Sheet-1 List Count? Discuss
• Download CSV : we currently store only LinkCount & not Singular or Plural text; by design?
• Delete on an empty cell changes cell text from Empty to Links
• Delete on HM/MM with 2 links - saw following error
  number 2 is not iterable (cannot read property Symbol(Symbol.iterator))
• Delete on MM link field in actor table : Cannot DELETE /api/v1/db/data/noco/wedge_antilles/Actor/3/mm/Film%20List/
• Shared grid view throw's error (tried over PG sakila db, actor table, sqlite root)
• Lookup broken; API returns only null
• Locked view - should we open child modal on clicking link field?
• Duplicate table - City failed
• Disable sort options if we do not intend to support

• Locked view : double click on 'Link' opens up child list modal
• Change display text from Link to another record to Links in both lookup & rollup creation modal
  
• For Lookup, Expand icon missing on click over cell. Double click, increases size of block.

• Tooltip missing
  

• Belongs to : provide link to open associated record on clicking over chip

• Display suffix (Links, Cities, Actors) is always showing plural; for 0 Link - we can display "Empty" text in grey?

• Could be an issue in develop too -- escape doesn't close edit column modal
  

• Create self link; delete self link column; additional system field is not removed. Trying to manually delete leads to error. below images show before and after for show system fields. Notice additional 'Actor List'. This was tried with sqlite root db, pg sakila ext db
  
  

• Shared grid view, double click on link cell; throws error
  

• Unable to add links from Shared form view (link record modal pops up; selection doesn't get recorded). Issue also noticed when trying to insert new record using expanded record form on grid

• Toolbar filter query doesn't work for link field; if by design, let us disable that option

[dstala]

• Limit column name, display text for singular & plural with links to 59 characters
• Also display error below text box once user exceeds feeding in 59 characters. currently we display after it exceeds 255 characters
• On cell, display value should always be in a single line; currently it spills over to multiple lines
• Lookup & Rollup column create & edit modal : for link selection - show only HM/MM/BT
• Lookup & Rollup column create & edit modal : show icons for field types
• Lookup to be supported only for BT relation
• HM, MM : drag drop show rollup instead of lookup (after corresponding LTAR is created)
• HM Filter : City List != 5 in country table gives error

[dstala]

• ERD - difference between develop & this PR can be noticed in below image. Only BT links displayed in this PR.

• Country has-many City, Using add new row using expanded form : add a BT link. Following error is observed

• Filter for numbers : != should include blanks. Example data (1,2,3,4,blank). Filter !=3 should result in (1,2,4,blank)
• Lookup Links; click on link displays error.

• Column header display needn't spread to multiple lines. Let us show ...
  

• Let the height of child list modal be fixed. Currently it auto shrinks when we have less than 10 records. not inconvenient to use page offsets.

• Transition issue observed during LTAR operations (only in PW)
• Duplicate project : view names differ (source had "Grid view", copy had "Table name" instead)

[dstala]

• Add new row, insert link before populating primary value

• Below portion will always remain empty as we will have 10 records per page. We can reduce padding
  

• Field name for Links, avoid "List". Example - default field name can be "Cities" or "City Count" instead of "City List"
