Intermittent Blank Grids in Production

Suite and Optimus Suite 5
#1

We’ve had this problem for a while, but it seems to have become worse.

Basically, something happens and every dhtmlx grid thereafter displays blank, no rows.

I believe, but I’m not 100% certain, that this error accompanies the start of the problem:

TypeError: Result of expression ‘this.entBox.parentNode’ [null] is not an object.

#2

This error occurs if script cannot find id of grid container on the page. Try to move code of grid initialization to the body “onload” event:

<body onload="doOnLoad()"> ... function doOnLoad(){ // init grid here }

#3

The thing is, the grids work 99% of the time (all the init occurs in onload). This is a heavily used app.

Any ideas why it might occasionally happen? Could networking problems cause it?

Also, after the grid becomes blank, ALL dhtmlx grids thereafter are blank until a full page reload.

#4

Probably page is loaded too slow so by the time of grid initialization grid container is not rendered yet.

#5

And that would cause all the other grids to load blank also?
