Re: AjaxCallListener and promises

2017-05-03 Thread Martin Grigorov 
Hi,

No, Wicket doesn't use the return values for all handlers but
"preconditions" [1].
And even for preconditions the only value that matters is the literal
*false.*

My bad. Problem solved, accidentally this part of  code was within a
block of markup text where all whitespace was replaced with non breaking
space.

Nbsp looks the same for naked eye but a diff tool shows the difference, and
obviously browser will render differently  compared to

AjaxCallListener and promises

2017-05-03 Thread Boris Goldowsky 
Is there any way to use a method that returns a promise as the onBefore of an 
IAxaxCallListener?  I don’t want the ajax operation to move forward until the 
promise resolves.  Due to the nature of promises in Javascript, there doesn’t 
seem to be a way to simply wait for it.

Re: Question about ajax encoding/decoding, problem with image data url

I don't see any reason why this could break.
If you are able to reproduce it in a quickstart with 6.26/7.6 then please
create a ticket in JIRA.

Check what is in the Ajax response, not what is in the DOM.
Also you can check with Google Chrome. Maybe Firefox does something funky.

Question about ajax encoding/decoding, problem with image data url

2017-05-03 Thread Martin Makundi 
Hi!

I am trying to display (wicket 1.4) an image using base64 image data
representation.

For some reason the base64 gets garbled every time with ajax.

For example:

src="data:image/png;base64,iVBORw0KGgoNSUhEUgAAAcIAAACWCAYAAABNcIgQAAAKUklEQVR4nO3dzYoc1xkG4PcS+g5cVxDmAmzoC/BCm5BANrMIWXilCwgIvIl3hhC8CUYbe+WFcAgJWdgT8MI2xjEYjA0KGYSjmESYkSxLsmXHk0V1R6dPVff09H/JzwMHaTTVVae7xfnqfOen

Re: Modal dialog, form validation in AjaxBootstrapTabbedPanel

2017-05-03 Thread Martin Grigorov 
Hi,

I think I see the problem.
When using AjaxBootstrapTabbedPanel the tabs' content is loaded one at a
time. This makes it hard to validate the complete form because not all
fields are available at any time.
You may need to use
https://github.com/l0rdn1kk0n/wicket-bootstrap/blob/wicket-7.x/bootstrap-core/src/main/java/de/agilecoders/wicket/core/markup/html/bootstrap/tabs/ClientSideBootstrapTabbedPanel.java
instead. It will switch the tabs
via JavaScript and make the validation once you use the submit button.
If this doesn't help you then I'll try to take a look at your application
after work!

Re: Why has a cell item a model (and why is it a model with the populator (with the property) of the column)?

2017-05-03 Thread Sven Meier 
Hi,

a cell item is an org.apache.wicket.markup.repeater.Item, and each item has
a model - so AbstractDataGridView just uses a model containing the
ICellPopulator for that.

It seems strange, that all cells of a row share the same model object, but
it does no harm.

Do you see a problem?

Have fun
Sven

Why has a cell item a model (and why is it a model with the populator (with the property) of the column)?

2017-05-03 Thread Eric J. Van der Velden 
Hello,

I don't understand why a cell item gets a model, because I have not seen
where it is used. Only the model in the row item is used, together with the
property of the column.

Also why is the populator of the column in that model?


public abstract class AbstractDataGridView extends DataViewBase
@Override
protected final void populateItem(final Item item)
{

RepeatingView cells = new RepeatingView(CELL_REPEATER_ID);
item.add(cells);

int populatorsNumber = populators.size();
for (int i = 0; i < populatorsNumber; i++)
{
ICellPopulator populator = populators.get(i);
IModel populatorModel = new Model<>(populator);
Item cellItem = newCellItem(cells.newChildId(), i,
populatorModel);
cells.add(cellItem);
...

For example here we see that the row model + property of the column is
used, and not the model of the cell item:

public class PropertyPopulator implements ICellPopulator
@Override
public void populateItem(final Item cellItem, final
String componentId,
final IModel rowModel)
{
cellItem.add(new Label(componentId, new PropertyModel<>(rowModel,
property)));
}

Thanks.
