extjs and webwork: Show grid

Basically I have two questions: 1) I have a ext, webwork(struts 2) application. In the legacy application, it uses grid to show a table.

In one jsp files: it has following two lines:

listFilterWindows: $H(), treeListFilterWindows: $H(),

I am wondering are there anybody in this forum knows what this '$H()' mean?

It is referenced by following way: Grid_.listFilterWindows[''] = new Ext.Window(....) 2) I am also wondering what does this has any meaning? Isn't it returns null?
