I think I create the details grid exactly as in the example  (http://trirand.com/blog/jqgrid.....qgrid.html -> Advanced/Master Detail), only that I call it the first time from the onSelectRow and not from outside. I also checked that way, initializing the details grid empty for the first time, as in the example. Same thing.

I'm confused with a way you want to achieve this.

The first common error is that you create the grid every time you select a row.

This is wrong. When the grid is created, every call to the code agin will return nothing

$('#grid_d').jqGrid(skill_options('rest/developer/' + row_id + '/skills'))

This will work only once.

In the demo we have a example just look on it.

I have a Master/Detail view in a page with two tables #grid and #grid_d. The table #grid_d shows the detail of the selected element in #grid. This is done rendering #grid_d in #grid.onSelectRow(). All info is loaded from a rest service.

The url to get #grid is /developers/ and the url to get #grid_d is /developer/DEV_ID/skills/. Hence when editing a detail row, the update url must be /developers/DEV_ID/skills/SKILL_ID.

In orther to do this, I get the current row_id in #grid.onSelectRow() and create a define function in #grid_d.onclickSubmit() which finaly puts both ids in the url together.

However, this works exactly only the first time, when #grid_d.onclickSubmit() is created first. Afterwards, all calls to #grid_d.onclickSubmit() will have the DEV_ID (row_id) from the first call (whatever you pick first). The SKILL_ID is correct.

I think there is a bug in reseting the function when the #grid_d is rendered for the second time, or is it a problem with the closure. If so, how should I be passing the DEV_ID instead?

In the code below, DEV_ID is the id from the #grid model, and SKILL_ID is the topic.id from the #grid_d model.I used jquery-1.10.2 and 1.9.1,  jqGrid  4.4.5 and jqGrid  4.5.2 .. all the same.
