branch 2.0-frozenRowsAndColumns : this.data.length undefined #88
Description
this.data in slick.grid.js function setFrozenOptions() can sometimes be null, so calling this.data.length will cause a javascript error.
probably you can update the code to avoid this scenario.
current : var dataLength = getDataLength() || this.data.length;
proposed: var dataLength = getDataLength() || (this.data || []).length;
by the way, thank you for adding this feature in slickgrid 👍
