Environment

• Platform version: 7.0

Description of the bug or enhancement

• FTS for browser screens loads immediately hit infos and tooltip description for all searched entities
• It consumes a lot of memory
• Try to load tooltip information lazy, when you clicked on an entity in a browser screen.
• Thesis dependent changes: https://git.haulmont.com/thesis/app/blob/master/modules/web/src/com/haulmont/thesis/web/gui/components/filter/LazyHitInfoMap.java
  • Minimal reproducible example
  • Entity model: an entity with attachments
  • Create instances of the entity with attachments. Attachment files must be large.
  • Try to find by FTS condition in the entity browser.
  • Check a memory consumption by heap dump.

For QA: tooltips are generated for displayed entities only. Check that if there are a lot of indexed entities (thousands) that meet full-text- search criteria, no out-of-memory errors appear.

The cuba.gui.genericFilterFtsTableTooltipsEnabled enables and disables tooltips generation at all. Tooltips generation takes a lot of time, so for new projects created with FTS addon, tooltip generation will be disabled by default.

Breaking change - for old projects, users will have to set the cuba.gui.genericFilterFtsTableTooltipsEnabled property manually if they need tooltips.
