Re: Initiating File Download through Ajax is not working

2012-03-13 Thread Rain... Is wet!
I'm using the AJAXDownload with success in my current project (Wicket 1.5.4).

Just create an instance of the AJAXDownload, override getResourceStream to
return your IResourceStream and getFileName (would recommend it) to return
your desired filename.

When done, add it to your AJAXSubmit component (AjaxLink, AjaxFallbackLink
or AjaxButton... or similar) and initiate your download in its onSubmit
method via yourAJAXDownload.initiate(yourIResourceStream);.

Basically its 100% like in the example given here:

Re: Dot in DataTable Columnheader - not allowed?

2012-03-13 Thread Rain... Is wet!
@Igor Vaynberg-2: I guess You're right.
The error is outgoing from the PropertyColumns used in the DataTable.
Unfortunately we already extended the Datatable way too far to just switch
to another Column-Type (it's the time factor). But we will (hopefuly)
remember that cicumstance in our next project. For now it's goin fine with
just abandoning dot's as column descriptors^^
Thank You anyway :)

Dot in DataTable Columnheader - not allowed?

2012-02-23 Thread Rain... Is wet!
Hi,
I just explored a strange behavior of the DataTable component in Wicket
1.5.4.

If a column header has a . (dot) in it's name, the values of the cells
belonging to to that column aren't rendered properly - they are rendered
like empty cells.

For example:
If I do a SQL-Command like 'SELECT f.Value f.val FROM values', all cells
in that column are rendered emtpy (but they are properly accessible through
the DataProvider).
If I instead do a SQL-Command 'SELECT f.Value fval FROM values',
everything works like a charm.

This problem seems to have nothing to do with the charset (its UTF-8),
because other special-chars won't harm the rendering. Neither seems it to
have to do with the DataProvider, because sorting and everything else worsk
as suggested too (checked via Debugger).

Does anybody else ever seen this behavior or maybe has a clue on where to
fix that instead of just not to use dots in column-headers?

Regards
  Rain... Is wet!

Re: Dot in DataTable Columnheader - not allowed?

2012-02-23 Thread Rain... Is wet!
Some more info:
My DataProvider is using a Model of the type ListHashMaplt;String,
Object, where list-index is acting as a table-row, the string is the name
of a column and the object is the value of a cell.

Re: Custom CSS-Class for OrderByLink (possible?)

2012-01-10 Thread Rain... Is wet!
Got what I want, but had to give up this approach :(

Instead of adding more css-classes, I just added a label to the
HeadersToolbar, to switch the ordering state via css background-image and
doing my checks for grouptotals in HeadersToolbar.onConfigure() where an
sumup-symbol is added as the new labels DataModelObject.

Custom CSS-Class for OrderByLink (possible?)

2012-01-06 Thread Rain... Is wet!
Hi,
I'm currently extending the DataTable and used classes to support some more
stuff.

I already extended OrderByLink to get the ability for interpreting
additional request-parameter and this is working just fine. The only thing
thats left for now is a way to extend the given SortState to provide +3
states (for every given one I need 1 more that represents an extended
version of itself) for 3 more css-classes. But as I can't extend enums
(SortState) and all major classes that deal with SortState (either in
SingleSortState and innerclasses in OrderByLink) are either static or final
I don't get the point on where to start, without the need of replacing
dozens of classes...

So my question is: Is there any easy way where I can hack my
extended-SortState in?

P.S.:
To determine the needed class it is a must have to have the ability to read
a attributes-list I added to the DataProvider-Class. I think this too is the
main reason why I have so much problems in dealing with all that
final-classes/-methods...

Re: Custom CSS-Class for OrderByLink (possible?)

2012-01-06 Thread Rain... Is wet!
In DataProvider i implemented a List of columns in which there should be
generated group-totals.
In addition to the given SortOrders NONE, ASCENDING, DESCENDING I need
NONESUM, ASCENDINGSUM, DESCENDINGSUM.
What I've come so far is the ability to set those attributes via an
additional request-parameter that is catched up in
OrderByLink.nextSortOrder(...). But what I can't from this point is to set
my new SortOrders and to implement the belonging css-classes that are being
set via OrderByLink.DefaultCssProvider - at least not without the need to
replace very much code and classes.

Re: Custom CSS-Class for OrderByLink (possible?)

2012-01-06 Thread Rain... Is wet!
Found an not so complicated way to implement own css-class to orderbylink.

After calling the constructor of the superclass I just removed the
standard-css Modifier and added my own implementation instead.

this.removeAll();
this.add(new HisOrderByLink.CssModifier(this, cssProvider));

And in my CSSModifier I implemented the Check i needed.

Unfortunately this was a false approach :D I won't need a class on the
OrderByLink but on the container holding the .th - I will investigate
further on this^^

Re: Numeric Filter on TextField

2012-01-05 Thread Rain... Is wet!
In the markup, add the attribute onkeypress=YOURFUNCTION(event) to your
textfield.

In your function get the keycode from the event and then use if/else or
switch/case to return true on every keycode from 47 to 57 (ASCII-codes for 0
to 9) or to return false for any other keycode.
Get yourself an ASCII-table to find other keycodes that might be worth to be
lettin through (ENTER on IE8, or ctrl on FF and others).

Re: DefaultDataTable column style and orderbylink

2012-01-04 Thread Rain... Is wet!
Maybe You can check the actual class of the columnheaders on the pages loadup
and then add a class to your columns via javascript.
With the use of the jQuery framework this should be a quite easy task.

Re: my book updated for Wicket 1.5.x

I already got Wicket In Action, and am playing with the idea to buy your book
aswell.
What gets in my way is the idea to buy the paper-version and then have to
pay (even with a discount) for the electronic-version again...
To bring an example on whats in my mind: If I paied for the business class
in an airplane but - as an example for the reason to get the chance to sit
beside a beautiful woman - want to get a seat in the economy class I
although won't have to pay again...
