Re: CompoundPropertyModel - white space

2021-06-08 Thread Sven Meier


Hi,

by default textfields trim their input, so I'd expect the total count 
characters to be correct to the processed input:


  "f " + "m" + "l" -> "fml" = 3 characters (also a space was entered 
after the *f*


You might want to override #shouldTrimInput if you want to keep the 
whitespace.


Have fun
Sven

Hello,

Apache Wicket version used: 8.12.0

I need to show total characters entered into First, Middle and Last name
text fields + one drop down for Suffix. The combined length of these four
fields should not exceed the set limit.
For this, I have added OnChangeAjaxBehavior to all the three text fields +
the drop down.

These fields are bound to the respective bean properties using
CompoundProperyModel. The bean has a generic getter method to calculate
combined length without trimming white space from any field.

Issue:
The CompoundPropertyModel bean setter method is not called when a white
space is entered after any letter in the field.
For example, entering "f" in the first name will call the setter method,
but entering white space after "f" does not call the setter method until
the next character is entered.
This is messing up the total chars count.

Here is how the length looks like without any white space trimming:

(1) F + M + L = "f" + "m" + "l" = 3
(2) F + M + L = "f " + "m" + "l" = 3 (Please note the white space after f)
(3) F + M + L = "f n" + "m" + "l" = 5

As one can see, the 2nd scenario is what I am trying to solve.

The OnChangeAjaxBehavior event is called when entering the white space, but
the bean setter is not, causing misleading total chars count.

Any suggestions?

Thank you,
-Mihir.

Re: CompoundPropertyModel: override method or catch exception

2015-06-17 Thread Martin Grigorov

Hi,

Then you need to roll your own IModel and use it instead of
CompountPropertyModel.
**PropertyModel classes use reflection to find and call the setter and
getter methods.

To go with my other thread

http://apache-wicket.1842946.n4.nabble.com/TextField-AjaxEventBehavior-onBlur-onEvent-tp4671150.html

about the same form page, I have an issue with the CompoundPropertyModel.
There is a TextField in a form on this page, and the corresponding setter
in
the model can throw an exception. When it does, wicket crashes the page. It
seems that it's using reflection by grabbing the name of the component on
the page, and looking for a setter for that component in the model
automatically behind the scenes.

What I need to have happen is either I can somehow override that method
through the CompoundPropertyModel, or just catch exceptions from the model
in general, or maybe some other mechanism. In any case, what I need is to
be
able to cleanly reset things on the page in the case of an exception rather
than the page crashing altogether.
