Hi Martin,
This seems to be the normal JSF behavior. Let me explain :
- first, your boolean ra.kmt is false, inputText is present and
inputTextArea is not.
- after a click on your checkbox, ra.kmt is changed and becomes true.
So in the component tree, the inputText component is NOT present
(rendered=false). That's why it doesn't get the new value. I think it
might work if the checkbox was after the inputText, but I wouldn't
recommend you to expect this to always work in all cases.
However, the inputText should get a ValueChangeEvent, so if you add a
valueChangeListener, you should get the new value. You may want to
copy it yourself in ra.debitnote.
If it's possible for your project, another solution would be to work
with a jsf library such as Apache Trinidad. In Trinidad you have a
tr:inputText component that does inputText AND inputTextarea,
all-in-one, depending on the number of rows you set. Thus it would be
the very same component whether the checkbox is checked or not.
Your code with Trinidad would look like :
<tr:selectBooleanCheckBox value="#{ra.kmt}" autoSubmit="true" id="chooseSize"/>
<tr:inputText value="#{ra.debitnote}" rows="#{ra.kmt ? 4 : 1}"
partialTriggers="chooseSize"/>
Hope this helps,
Regards,
Cedric Durmont
