If you've used GXT's Grid and RowExpander plugin, you know what I'm talking about. The current design lacks the ability to put arbitrary widgets into the expanded row. XTemplate is great but it falls short when you want richer user interaction inside the expanded row (something like Google Reader's grid).

At my work I created a modified RowExpander (I call it WidgetExpander) to tackle this limitation and it has been working great. So I created a project on Github (http://github.com/kevinjqiu/gxt-widget-expander) to open source this part. Hopefully you'll find this useful as I did.

I've been using the one that Arno came up with, I tweaked a bit and he formalized but I've had a few problems with it.

I'll give this a go and report back!

nice :-)

one thing i see that the expander cache the widgets. if the models are changing later then the changes are not visible with this plugin. maybe add some handling to make it working with changed models. or a option to disable the caching.

You're right. I checked in a new version. If the passed in model is a subtype of ModelData (in which case a PropertyChangeListener may be attached), I invalidate the cache when any properties of the model change.

This plugin looks awesome and is exactly what I need. I also noticed the plugin made by Arno, any recommendations on which one is easier to use?

I simply want to use this for a Ticketing system type WebApp, where the use can click the Plus to expand the Ticket topic and be able submit an entire form or response. Which plugin would you recommend, to do something like that, where I want the row expander to just expand into a blank form.

I am a little bit confussed with this one only in the fact that in the Demo Application it calls
final WidgetExpander<User> expander = new WidgetExpander<User>

But because my form wont really have a DataModel what would i want to do? like what if i just wanted to add a button or checkbox

I'm trying to use this WidgetExpander grid plugin in a nested way and having troubles, when I have a grid inside a grid it works just fine, but if the second grid has also the plugin to get another grid inside (2 levels of nesting) it doesn't work.

Has anyone faced this?
Thanks in Advance.
