Grid recalculateColumnWidths doesnt work first time but later

I have a grid, updating data by clearing the date from container & adding, and than calling recalculateColumnWidths.

I’m doing this inside enter() method of the view & also when user press a resresh button.

when I first enter the page, the columns widths are not correct but when I press the resreh button, which calls same method with enter() calls, then Grid column withds are fixed.

is it a bug or am I doing something wrong ?

İssue resolved with 7.5.7 version.
