Hi Janak!
Thanks for answering.
I already fixed the problem here. The bug was that I called
super.updateToModel before reformatting the text. Now the call to
super.updateToModel is the last call of the overridden updateToModel and all
works as expected.
Instead of ULC's data types we use domain values - immutable objects. The
classes for those objects are deployed on the client and server. and they
are serialized as strings between client and server. factories that are also
available on the server and client are used to create those domain values
from strings and to create strings from the domain values.
A domain value can have several string representations - a date can be typed
in as "10.10.2006", "10102006", "1010" - but there is only one default
string representation - "10.10.2006" in this case. When reformatting we
reformat the string to the default string representation.
Anyways: it works now.
Cheers,
Robert

Hi Robert,
Could you please tell me:
1. what is the purpose behind overriding updateToModel() method?
Is it just to do formatting?
If so you can use one of the existing IDataType implementations of ULC
or
implement your own.
2. What exactly are you doing in the reformat() method?
When you call UITextComponent#setText() directly (as against
getBasicTextComponent().setText()), ULC first removes the document
listener,
sets the text, and sets the document listener again. This is the reason
why:
1. valueChanged event is not generated
2. no formatting is done because it is the document listener which in turn
invokes the formatter (i.e. the data type).
Kindly provide more details so that we can find an appropriate solution.
Thanks and regards,
Janak

Subject: [ULC-developer] UITextField.updateToModel problems
Hi!
We have an extension that extends ULC/UITextField. We have overridden
updateToModel to reformat the typed string after the typing is finished:
protected void updateToModel(final boolean displayFormattedValue)
{
super.updateToModel(displayFormattedValue);
if (displayFormattedValue)
{
getBasicTextComponent().setText(reformat(getBasicTextComponent
().getText()));
}
}
The problem with this is that it sometimes an extra valueChangedEvent
after
leaving the textfield.An alternative looks like this
protected void updateToModel(final boolean displayFormattedValue)
{
super.updateToModel(displayFormattedValue);
if (displayFormattedValue)
{
setText(reformat(getBasicTextComponent().getText()));
}
}
Now the extra event isn't created, but the text changes to the originally
typed in text when the textfield gets the cursor again.
For example if I typed in "1020", it is displayed as "10:20" after the
reformatting and again as"1020" once I click into the textfield.
Is there some way to reformat the text and make it stay reformatted
without
the extra valueChangedEvent?
Cheers and thanks in advance,
Robert
