Change the view of tomahawk component
Hi all, i am really new in all of this jsf stuff. I would like to use the component to built a calendar portlet in Liferay, but i'd like to change the rendered view to a simple list. Within the list all entries should be listed with date, time, title etc. I don't need any other views like workweek or month scheduleviewmode. Has anybody got an idea how to start impementing this. Regards Lucas
Re: confused about selectOneItem and converter and data binding
An html select element looks like this:
Volvo
Saab
Fiat
Audi
You have:
where the getSelectItems() method returns a list of SelectItem objects
whose string is the text you want to display, and the value is a
ComplexProp object, right?
So the renderer for the f:selectItems writes out one tag for
each item in the list. The body text for the tag is taken from
the SelectItem.label property. The SelectItem.value is a ComplexProp
object, and so the converter.getAsString method is called to generate
the string to write out as the "value" attribute. Obviously this occurs
once for each item in the list.
When the form is posted back, the browser will include in the posted
form data the *string value* of whatever option was selected by the
user. JSF calls the converter once, to map this string back to a
ComplexProp object, then (in update-model phase) stores the resulting
object using the "value" EL-expression of the h:selectOneMenu component.
So on render, getAsString is called N times, and on postback getAsObject
is called once.

Re: confused about selectOneItem and converter and data binding
Hi dushyant,
thanks for response -
which value I should return in getAsString method? - actual Key
element or Value element? - because the selectOneItem is populated by
SelectItem's elements.
and why in debug I see that getAsString method is being called for N
times (over all elements in binded array)?

Re: confused about selectOneItem and converter and data binding
In case of selection, the getAsObject would convert the selected value as
specified and send it to BB. In getAsString() method you again have to specify
some code to change the BB value into one of the values in the selectItem list,
bound to the selectOneMenu component.

how to align to the right hand size of the screen?
I have a form which must always placed at the left, then I write another form and I want the form place in the right hand size of this form, by now the new form always placed under the left hand size form, any method (e.g. StyleClass) can placed a form to the right hand size? (the left hand size form is always reused and nearly included in every form, I want any new form placed in the right hand size of this form) 為了不斷提升Yahoo!
