jQuery Grid Plugin - jqGrid

We are evaluating a few javascript frameworks and were looking at the grid widget offered by dfferent frameworks.

We are using jqGrid as a part of jquery evaluation.

We are using subgrid with editable cells. So there are certain columns in the subgrid that need to be made editable.

The subgrid rows are made editable by clicking a button similar to 'Row Editing' -> 'Custom Edit'  example that you have in the jqGrid demos.

At a given point in time, only one sub grid row needs to be editable (there might be several rows in a subgrid).

 I had to modify grid.inlineedit.js to pass the subgrid id along with the row id so that I can 'restore'  'other' subgrid rows that were made editable by the user.

if( typeof oneditfunc === “function”) { oneditfunc(rowid,this.id); }

I also don't want to fire a server side call on edit of a sub grid cell. So i commented out that part as well.

Now I'm not sure how to build the file “grid.pack.js” with my changes.

 I ran JSMin on the modified grid.inlineedit.js . But I'm not able to proceeed further.

Can you please provide instructions on how to build a lean and mean jqGrid distribution with my changes. 

Your help is greatly appreciated.

thanks,
Karthik
