jQuery Grid Plugin - jqGrid

Problem 1:

While playing with 3.6.2, I think I may have hit a bug where optional data are missing default values.

What I see is that in the navigation bar (pager) of a grid, next to the icons, I see an "undefined" label. Following the code in "grid.formedit.js" to the "navGrid" function, I see that things like "o.addtext", "o.edittext", "o.viewtext", etc. being rendered but they do not have a default value in the local variable "o".

Problem 2:

I see a message box with the text "undefined" in the middle of my grid. I think it is where the "Loading..." message should be. Also, the "undefined" message box does not fade away like the "Loading..." message does.

Problem 3:

I am missing the "Page <box> of <total>" and "View ... - ... of ..." parts on the pager.

Any pointers to directions of troubleshooting would be greately appreciated!
