The framework ships a set of inspection tools for looking into a running application — the live query, the editor state, an entity’s data graph. The inspectors are excluded by default and enabled via configuration values, typically during development.
1. Entity viewer
Displays the selected entity as a navigable tree: every attribute with its type and value, original values for modified attributes, and foreign key references expandable into the referenced entity’s tree — the fastest way to answer "what is actually in this row".
Included by default in every table panel, on CTRL-ALT-V; excluded via EntityTablePanel.Config.INCLUDE_ENTITY_VIEWER.
2. Query inspector
Displays the SELECT statement the table’s query model will run, updated live as conditions change — see Query Inspector. Enabled via EntityTablePanel.Config.INCLUDE_INSPECTOR, opened with CTRL-ALT-Q.

Note
|
The query inspector requires the codion-framework-db-local module on the classpath, since it renders SQL — on a purely remote client it is unavailable. |
3. Editor inspector
Displays the state of an edit panel’s editor: each attribute’s value, original value, modified/valid/present flags and validation message, along with the INSERT and UPDATE statements the current state would produce. Detail editors appear as nested inspectors.
Enabled via EntityEditPanel.Config.INCLUDE_INSPECTOR, opened with CTRL-ALT-R when the edit panel is focused.
EntityTablePanel.Config.INCLUDE_INSPECTOR.set(true);
EntityEditPanel.Config.INCLUDE_INSPECTOR.set(true);4. Dependencies viewer
Displays the entities depending on the selected rows — the incoming foreign key references — as a tabbed pane of table panels, one per dependent entity type, navigable with CTRL-ALT-LEFT/RIGHT. Available from the table popup menu, and shown automatically when a delete fails on a referential integrity constraint, if ReferentialIntegrityErrorHandling is set to DISPLAY_DEPENDENCIES.
5. SQL tracing
Traces the queries a local connection runs — see EntityApplicationPanel.
