f.Host = null blowing up

[nswiderParticipant]

So the chain of events goes like this.

1. Load Grid
2. call window.open to open another page
3. jqxGrid blows up with the error
JavaScript runtime error: Unable to get property ‘css’ of undefined or null reference

here is the code throwing the error..
function(){if(f.host.css(“visibility”)==”visible”){f._updatesize(true);clearInterval(f._intervalTimer)}},100)}}else{f._updateTouchScrolling()}};this.dataview.databind(g);if(this.dataview.isupdating()){if(d!=undefined){this.dataview.suspend=false}else{this.dataview.resumeupdate(fals…..

the error is coming from the first f.host.css above.

please help this we can not purchase with this error. It shows up at other places as well.

Thanks in advance

ie11 windows 8.1 jqx 3.8.0

turned out to be two threads building the grid at the same time.

came back with 1 thread on window open

[nswiderParticipant]

ok it occurs on two threads two grids also

[nswiderParticipant]

happening on .jqxGrid(‘destroy’); 1 thread

calling this back to back on two grids causes the second one to fail

[nswiderParticipant]

At the end of the day I just had to fix the code..

I replaced
if(f.host.css
with
if(f.host && f.host.css

in the file jqxgrid.js in two places. Everything is working fine now.

Let me know your two cents on this.

Thanks
