Re: inmethod-grid refresh issue
Thanks Marc, This is indeed the issue, i am going to make it light weight for now and provide an alternate mechanism to launch the other features that are stuffed in here at present.

Re: inmethod-grid refresh issue
I bet we are getting to the source of the problem.
Non light-weight columns like yours, create the components just once when
the grid is first rendered. So the model instances you pass when you create
the Component will remain the same even if you update the grid.
I believe non-lightweight columns where designed as a means to create
editable rows and shouldn't be used otherwise.
I don't think you really need to use a component for what you are trying to
accomplish.
Maybe you should override "public IRenderable newCell(IModel
rowModel)" instead and write whatever markup you need directly to the
response.
Hope it helps

Re: inmethod-grid refresh issue
Actually i have overridden
public Component newCell(WebMarkupContainer parent, String componentId,
IModel rowModel)
{
...
}
to use a separate panel for cell content, due to other functions, will not
make any difference?
Thanks

Re: inmethod-grid refresh issue
You should start debugging your project instead of using "print" to see
what is really happening (call stack, variable values...).
PropertyColumn always calls the get method of your model object:
@Override
public IRenderable newCell(IModel rowModel)
{
return new IRenderable()
{
public void render(IModel rowModel, Response response)
{
CharSequence value = getValue(rowModel);
if (value != null)
{
response.write(value);
}
}
};
}
private CharSequence getValue(IModel rowModel)
{
I rowObject = getModelObject(rowModel);
P property = null;
if (rowObject != null)
{
try
{
property = getProperty(rowObject, getPropertyExpression());
}
catch (NullPointerException e)
{
}
}
CharSequence string = convertToString(property);
if (isEscapeMarkup() && string != null)
{
string = Strings.escapeMarkup(string.toString());
}
return string;
}

Re: inmethod-grid refresh issue
Also i put a print on every getter but it only prints on first call on a set of rows, if you filter among those rows its never get called, i suspect the grid has rows cached and its assuming nothing changed so using those rows again as a subset of previously created rows.

Re: inmethod-grid refresh issue
yes i am using property columns in grid to map columns to properties of model. Data Source is a very simple implementation just filter model objects in a cache into a list of filtered model objects. Context is user and also his filter settings. If a user can not see value from source x so his calculated value would be total value minus what he can not see, there are several other parameter to this context but this is what it is for all parameters. Also if he has filtered the view on XYZ, the calculated value will exclude everything that comes from XYZ (including rows). Its like total sales coming from multiple accounts but user may be seeing only one or few accounts (not all) so sales should show what is the sale from those selected accounts (in view).

Re: inmethod-grid refresh issue
In your IDataSource code, you left out the implementation "public IModel model(MyModel object);", I'm quite suspicious that your models are the source of the problem. I'm assuming that you are using PropertyColumns in your grid, with these columns, your getter method should be getting called every time. You also say "...that may return different value if the context changes..." what does "context" stand for? -- Marc Nuri www.marcnuri.com On Mon, Mar 4, 2013 at 5:39 PM, saty wrote: > Its a regular java bean with properties and setter and getter methods. > Grid uses the expression to map a column to a particular property on row > model (MyModel). > > Thanks > > > > -- > View this message in context: > http://apache-wicket.1842946.n4.nabble.com/inmethod-grid-refresh-issue-tp4656910p4656945.html > Sent from the Users forum mailing list archive at Nabble.com. > > - > To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org > For additional commands, e-mail: users-h...@wicket.apache.org > >
Re: inmethod-grid refresh issue
Just managed to get a workaround to fix the problem. I have to add a dummy property to the model object and calculate that property within my data source and than use that property to map to the calculated column. However since i can not change the state of original shared model object, so i have to clone it first (for every user, not a good idea ) and it introduces whole set of new problems. Does that ring a bell, how the problem can be solver without all this? When the model expose a getCalculatedValue method, why would not the grid call that method to render the row every time on a column that is mapped to an expression 'calculatedValue' ?

Re: inmethod-grid refresh issue
Its a regular java bean with properties and setter and getter methods. Grid uses the expression to map a column to a particular property on row model (MyModel).

copied relevant potion above, i can see query method is called every time,

Re: inmethod-grid refresh issue
grid.markAllItemsDirty(); grid.update(); This does not help, for some reason grid is smart not to regenerate a row for a model it already did. I can see my getXXX method is called by grid only first time and than its never get called again so the column shows what was calculated for the first call. To be more specific, if the grid shows 20 rows and than i filter to show 10 out of those 20 rows, it does not call the getXXX methods on my model object. However If i change filter setting so it has to now show 30 rows (20 previous and say 10 other rows) , it does call the getXXX methods again. Not really sure what controls this behaviors and how to override it.

Re: inmethod-grid refresh issue
Ok, I see. Either way if it is a DataGrid, calling markAllItemsDirty() and update() from your ajax request should do the job. -- Marc Nuri www.marcnuri.com On Mon, Mar 4, 2013 at 4:35 PM, saty wrote: > Thanks Marc, i will take a look at these methods if they can help, however > my > equals method can not help here as i said previously some columns are > derived in the sense they dont return an attribute of the object but a > value > which is derived from the context (and object state) in which the method is > called. > > > > > -- > View this message in context: > http://apache-wicket.1842946.n4.nabble.com/inmethod-grid-refresh-issue-tp4656910p4656938.html > Sent from the Users forum mailing list archive at Nabble.com. > > - > To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org > For additional commands, e-mail: users-h...@wicket.apache.org > >

Thanks Marc, i will take a look at these methods if they can help, however my equals method can not help here as i said previously some columns are derived in the sense they dont return an attribute of the object but a value which is derived from the context (and object state) in which the method is called. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/inmethod-grid-refresh-issue-tp4656910p4656938.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: inmethod-grid refresh issue
Hello Saty You should check methods "markItemDirty(IModel model)", "markAllItemsDirty()" and "update()". This are the methods you are supposed to be calling when refreshing the grid's content. You should also make sure that the equals() method of your model objects return false when both objects aren't equal...

inmethod-grid refresh issue
I have this strange case where when i do ajax target.add(grid), it does call my grid datasource to request the rows that the grid need to populate but when it finds that rows to be displayed are same what grid already has it does not recreate the grid (i can say that as i notice my get methods on model are not called). My guess is when it need to display same rows (model) it will not run through the list of model objects again that it need to show, however in my case there are few derived columns (hence corresponding get methods) that may return different value if the context changes (controlled by several filters on grid). How can i force the grid to run through the model list every time to refresh the grid, regardless? Not sure if above explains the problem clearly, please do let me know if more details are required.
