GridPanel reconfigure

[hhiranan]

I tried posting in my other thread, but it seems not to work, Maybe my
post was too long or something. Here we go again.

I have rewritten my code to use GridPanel.reconfigure. The problem now
is much worse. I know that reconfigure is a requisite for dynamically
loading data into GridPanel, so I am going this way. Below is all the
code that is involved.

////////////////////////////////////-----------
StatusAggregates / StatusAggregatesAsync / StatusAggregatesImpl
////////////////////
public interface StatusAggregates extends RemoteService
{
public CurrentStatusAggregatesDO[] getStatusAggregates (String
token) ;

public static synchronized StatusAggregatesAsync getInstance()
{
if (ourInstance == null)
{
ourInstance = (StatusAggregatesAsync)
GWT.create(StatusAggregates.class);
((ServiceDefTarget)
ourInstance).setServiceEntryPoint(GWT.getModuleBaseURL() +
"com.trafficland.vqm.VQM/StatusAggregates");
}
return ourInstance;
}
}
}

Hi hhiranan,
Did you try to use firebug for firefox to see if you have an error?
It's very helpful...

In the other hand... I'm reviewing your code to detect some
problems...

One tip:
Sometimes... if the data in one field in one record is different of
the type that you have declared or is missing or is null, perhaps it
breaks the load/reload mechanism...

Leo

[leo_BsAs]

Another way to do the same:
As you know... in hte GridView there is a methos called "setEmptyText"
where set the text when there is no data to display...
You could set differents text to the GridView when you get an error
from the service... and the refresh the view...
(I could'nt test it, but sounds logic). Eg:

grid.getView().setEmptyText("ERROR!");
grid.getView().refresh();

In this way you don't have to redefine the grid every time you get an
error... Just configure it once, and the play with the setEmptyText
stuff...

I hope it helps you...

Leo

[hhiranan]

Thanks for the help. I'll give it a try and let you know in a few.

Still have the same problem

Here is the new code:

public class StatusSummary extends Module

}

{

tablePanel.getView().setEmptyText("DATA ERROR:

}
else
{

if (temp.length > 0)
{
data = new Object [temp.length][3];
levelChartData = new int[4];

tablePanel.setColumnModel(columnModel);

tablePanel.setFrame(true);
tablePanel.setStripeRows(true);
}

}

Also, using firebug, I get no errors on console. Furthermore, the div
that should contain all the content is completely empty

thanks again

I have a few observations:

* A piece of your code is wrong... you declare a matrix of [n] x [3]
and then refers to the fourth position...

data = new Object [temp.length][3];

...

for (int i = 0 ; i < temp.length ; i ++)
{
data [i][0] = new
Integer(temp[i].getCount());
data [i][1] =
(temp[i].getStatus().getTitle());
data [i][2] =
(temp[i].getStatus().getDescription());
data [i][3] =
(temp[i].getStatus().getStatusLevelDO());

* In addition, after you set an empty message you should call:
tablePanel.getView().refresh();

* When you reload the store, try it in this way...
your code:

MemoryProxy proxy = new MemoryProxy(data);
ArrayReader reader = new ArrayReader(recordDef);
store = new Store(proxy, reader);
store.load();

tablePanel.setStore(store);

suggestion:

MemoryProxy proxy = new MemoryProxy(data);
ArrayReader reader = new ArrayReader(recordDef);

Store tmpStore = new Store(proxy, reader);
tmpStore.load();

tablePanel.getStore().removeAll();
tablePanel.getStore().add(tmpStore.getRecords());

I hope it work...

Changed the code to fix the obvious problem. Nothing is adding the
table to the 'this' panel.

tablePanel.getView().("APPLICATION ERROR: remote call for data

tablePanel.setTitle("Status Aggregate Table");

this.add(tablePanel);

{

tablePanel.getView().setEmptyText("SERVICE/NETWORK

}

{

I moved from reloading data every time status changes occurred to only
loading it once, and put all the suggestions you made, other than the
store refactoring, in place.

I also did some testing with the RPC to see what's going on there. I
got what I expected.

Now, for no apparent reason, whenever i try to load this panel, I see
it start to load, with no content, and then suddenly the page
refreshes.

Odd behavior. I am working on debugging it right now.


Below is the current state of my code.

Thanks again for taking a look.

Did you try this suggestion?

* When you reload the store, try it in this way...
your code:

MemoryProxy proxy = new MemoryProxy(data);
ArrayReader reader = new ArrayReader(recordDef);
store = new Store(proxy, reader);
store.load();
tablePanel.setStore(store);

suggestion:

MemoryProxy proxy = new MemoryProxy(data);
ArrayReader reader = new ArrayReader(recordDef);

Store tmpStore = new Store(proxy, reader);
tmpStore.load();

tablePanel.getStore().removeAll();
tablePanel.getStore().add(tmpStore.getRecords());

Instead of setting a new Store every time you call your reload method,
try to create a new Store to load the data, and then pass to the grid
store the new records...

[hhiranan]

Thanks for all the help so far. I tried your most recent suggestion.
Every variation of it failed and caused the same problem. The page
would reload every time the StatusSummary panel is loaded. I am
certain this is due to the fact that I no longer reload data. I only
loads it once. If it's not loaded, I assume that the EmptyText is what
will be shown.

LEO: Thanks again for helping me out so much. I'm going to continue to
work on it.

If there's anything else you see that may be suspicious in the code,
let me know.

You are the man. Thank you for helping me resolve the issue.

[leo_BsAs]

Did it work?

[hhiranan]

Fantastically. Everything worked well, i added some more custom code
to get it to look as per reqs.

I took that code and used it again, this time for a different
application and I'm having the same problem, where the page refreshes
every time the gridpanel is loaded. I tested the surrounding code, and
everything loads successfully. I have included the class in question
for your review. If/when you/anyone gets the chance to take a look. I
also tested the service/etc. I took the code directly from your
example, and my previously working code, so I was confident it should
work. Check it out. Right now i add the grid to the main panel to make
testing simpler, but give it a look.

Hi,
at first sight the only thing that I found was this:

resultsPanel = new Panel ();
resultsPanel.add(new HTML("TEST"));

try to set a FitLayout (or other) before add anything, eg:

resultsPanel = new Panel ();

resultsPanel.setLayout(new FitLayout());
resultsPanel.add(new HTML("TEST"));

Anyway... I'm reviewing deeper...

Thanks leo.

Even though i forgot the resultsPanel layout, it still worked. I've
been testing it, and the only thing that doesn't work is the darn
grid. Thing is driving me up the wall. I don't even know what's
missing/causing the error.

Thanks again.

After many reviews... I don't get anything but the follows....
Try to replace all the time that you initialize the data matrix
(statuslist) as empty in this form 0xn
statuslist = new Object[0][4];

instead of

statuslist = new Object [0][0];


perhaps it is a problem of matching the column definitions with the
data...

I don't know if it works... but try...

I was able to fix it earlier today. Dumb mistake on my part. Although
the advice you give makes sense, i'll probably put it in place just to
be on the safe side.

Check out my most recent post. I employed a nice little trick with css/
gridpanel to shade my rows. You may like it.

Thanks a bunch for all your help.
