1. Since we changed the defaultParams configuration option to paramNames in version 1.3.x,
you need to find all places in your project where this configuration option is in use and rename it to paramNames.
version 1.2.x code
var grid = $('selector').grid({
defaultParams: { sortBy: 'myCustomSortByParam', direction: 'myCustomDirectionParam', page: 'myCustomPageParam', limit: 'myCustomLimitParam' }
});
version 1.3.x code
var grid = $('selector').grid({
paramNames: { sortBy: 'myCustomSortByParam', direction: 'myCustomDirectionParam', page: 'myCustomPageParam', limit: 'myCustomLimitParam' }
});
