[CLOSED] html tag in text content breaks app
Hi everyone,
I'm trying to build an asset managment tool.
Left: category navigation by tree.
Top: asset navigation by grid.
Bottom: editor pane, inside a FormPanel.
The problem I'm having is that when I load an asset whose name and description contain html tags in the text, my app fails. Otherwise it functions as designed.
Specifically, after clicking the Bollay row in my grid, the directmethod fires and the TextFields in the form are loaded. However after that client clicks are not handled - clicking on a category does nothing, clicking on an asset does nothing. Not sure why, any help would be appreciated.
