dojox.grid.DataGrid in HTA Application

Written by Michael Schilling Thursday, 22 September 2011 10:24

When trying to load a dojox.grid.DataGrid object from within a HTA application using Dojo 1.6 you will receive an exception telling:

Unable to get value of the property 'html': object is null or undefined

This exception is not thrown and caught in the following method: dojox.html.metrics.initOnFontResize

In this function there's a check if the current browser is of type Internet Explorer and then some action is done when this is true. To solve this issue you can catch the excpetion and fail silently. I've been checking our applications thoroughly and couldn't find any downsides of this approach. So the original line looks like this:

f.onresize = f.contentWindow.parent[dojox._scopeName].html.metrics._fontresize;

The fixed lines would look like this:

try{

f.onresize = f.contentWindow.parent[dojox._scopeName].html.metrics._fontresize;

}catch(e){};
