Hi:
you said that ,I have done, and the dialog

To the backend executeCommand().
Now the question is, after executeCommand(),
Hou could I get the return value in the frontend.
For example, when I clicked backup button,

The dialog, click OK button, the backend executeCommand()
Do something, now, I need some value from executeCommand()
to frontend.
Sorry, I missed that your question was about executing backend

Backup dialog's OK button is represented by:
UICommand tempVar = new UICommand(OnBackup, this);
When user clicks OK button, that ^^ UICommand is executed.
Model's executeCommand should route flow to some onBackup()
method, I assume you already did this:
// inside TemplateListModel#executeCommand

else if (OnBackup.equals(command.getName())) {

if (windowModel.getProgress() != null || !windowModel.validate()) {

// this replaces dialog content UI with progress animated image
// to indicate that a call to backend is about to be initiated

Hi,Vojtech Szocs:
Thanks for your help, I have let it work,
The Error I got just because I miss the step 3 you noted.
Another question is how could I got the returnValue after
executeCommand , and let the returnValue display on the oher
Popup dialog.
Please add this into MainTabTemplateView:
...
getTable().addActionButton(new
WebAdminButtonDefinitionVmTemplate(constants.templateBackup()) {
@Override
protected UICommand resolveCommand() {
return getMainModel().getTemplateBackupCommand();
}
});
...
This adds a button under Template main tab. When clicked, it executes
given command (getTemplateBackupCommand) on model (TemplateListModel).
Model's executeCommand() ensures that backup() method is called. Inside
backup() method, you call setWindow(model) which triggers an event - UI
infra handles this event and uses getModelPopup (see TemplateModule)
to resolve window model to GWTP PresenterWidget which is then
revealed
as popup. This is how dialogs work in UiCommon / UI (GWTP) infra.
how could I got the returnValue after executeCommand
As I wrote above, executeCommand() just calls appropriate method (like
backup) on the list model. That method has no return value (void) since
it uses setWindow(model) to trigger event to notify UI infra to reveal
a dialog.
If you need to pass data to dialog, for example:
...
TemplateBackupModel model = new TemplateBackupModel();
setWindow(model);
... set window model's
Re: [ovirt-devel] Management network as a role - design proposal
On Thu, Aug 14, 2014 at 11:52:41AM -0400, Yevgeny Zaspitsky wrote: Hi All, The proposed feature will allow defining an arbitrary network in the DC as the management network for the cluster, which in its turn will allow assigning different VLANs for the management networks in the same DC. Feature page can be found here - http://www.ovirt.org/Features/Management_Network_As_A_Role . Please take a look into the page especially into Open issues section. I'd like to have your opinions on that. May I ask why you change the default management network from ovirtmgmt to Management? (And why the upercase M?) Regarding your open question: Creating new cluster would have to receive the new parameter (management network) This new parameter should be kept optional, with a default value of ovirtmgmt. This way, a user that is unaware of the new feature, would see no change in functionality. The feature page should discuss the possibility of chaning the management role. Is it supported after there are hosts in the cluster? If we allow that, there's a bit of complexity. The management network's gateway is used as the default route of each host. If you change the role, all hosts should be notified (with a new setupNetwork command). I think that the cleanest solution would be to allow editing, but report the hosts as out-of-sync. This approach requires a Vdsm-side change - it would need to report which of its network is the default route.

result.getReturnValue() returns VdcReturnValueBase
result.getReturnValue().getActionReturnValue() returns
the result of backend command (action) execution
For example, your backend command does this:
getReturnValue().setActionReturnValue(obj);
Then obj is what you get on frontend with:
result.getReturnValue().getActionReturnValue();
And how could I set it in the backend.

[ovirt-devel] What does your oVirt development environment look like?
Ever since starting to work on oVirt around 3 years ago I've been striving for the perfect development and test environment. I was inspired by Yaniv's recent deep dive on Foreman integration and thought I'd ask people to share their setups and any tips and tricks so we can all become better, more efficient developers. My setup consists of my main work laptop and two mini-Dell servers. I run the engine on my laptop and I serve NFS and iSCSI (using targetcli) from this system as well. I use the ethernet port on the laptop to connect it to a subnet with the two Dell systems. Some goals for my setup are: - Easy provisioning of the virt-hosts so I can quickly test on Fedora and CentOS without spending lots of time reinstalling - Ability to test block and nfs storage - Automation of test scenarios involving engine and hosts To help me reach these goals I've deployed cobbler on my laptop and it does a pretty good job at managing PXE boot configurations for my hosts (and VMs) so they can be automatically intalled as needed. After viewing Yaniv's presentation, it seems that Forman/Puppet are the way of the future but it does seem a bit more involved to set up. I am definitely curious if others are using Foreman in their personal dev/test environment and can offer some insight on how that is working out. Thanks, and I look forward to reading about more of your setups!
