[pde-ui-dev] Understanding Product Editor Validation

[Martin.Scheerer@xxxxxxx]

Hello PDE-UI Team,

I am currently developing an eclipse
forms application. I need some input validation like in the Product Editor.
I looked at the code and I understand most of it, but I can not find the
lines where the Error/Warning messages are created. 

As an example: 
In class WindowImagesSection
in method createClient()
all the inputs for different image file names are generated. Subclasses
of AbstractFormValidator
check their content. When there is no such file a error message is displayed.
But where is the code to display the message (it smoothly fades in just
where the page heading is, very nice ;-) ? I know how the String is constructed
but I can not find the graphical representation an the logic triggering
the display...

I hope my question is not completely
off-topic...

Thank you,

Martin
