I'm using a expander plugin together gridpanel, and I have a problem about this. When I active the plugin, the tabpanel can not closed. If I click in the close button, only the grid is hidden, but the tab is not destructed.

The firebug accuses a error at line 143 of RowExpander.js:
mainBody is undefined

tpl : new Ext.Template(
'<p>&nbsp;<b>Descrição:</b> {desc}</p>'

my first question is why are you not adding the grid directly instead of wrapping it a panel?

Because I creates a lot of grid, dynamically, according of the data clicked by user, so add in the tabpanel.
I solved the bug commenting the respective line [1] in the RowExpander.js.

[1] line 143: //mainBody.un('mousedown', this.onMouseDown, this);
