This is due to the Slickgrid upgrade. I will send the separate patch for the same.
Create a table with two columns id bigint (must be primary key) and name text. Insert couple of rows, now select any two rows and mark it for deletion, add new row and then click on Save button. Grid is not refreshed.
Delete button gets enabled if I select any new cell (type text) to enter some value.
Fixed
Add two new rows, don't click on Save button and delete couple of rows. Colour of newly added rows will changed to green.
Not applicable now
Create a table with Serial and Text column. Add two new rows, specify the values and don't click on Save button. Delete some rows and then click on Save button, data is saved in the database but grid is showing same serial id for two newly created rows. After re-run the query it shows the correct value.
As per steps given in RM, I have perform the same. But when I delete the row, delete button is still enabled and save button is disabled even though newly created row is still there. Apart from that code looks good to me. Please fix it.
