Displaying graphics question

Is there a Magritte description that know how to display graphics? I  
don't see anything that looks promising in the Magritte-Model- 
Description category, but I thought I had read something about it at  
one time.

MAFileDescription does that if the element is displayed in read-only  
mode. The editor in MAFileUploadComponent doens't do that per default  
anymore, because if it displayed huge images within forms wasn't that  
user friendly. However you can change that by subclassing  
MAFileUploadComponent.

Re: Differences w/ exception handling in Magritte..?

Where exactly do you get a recursion?

It looks like that this is exactly the point in time where I added  
code to avoid recursion when dealing with recursive descriptions. I  
guess the method causing trouble is  
MAValidatorVisitor>>#visitDescription:?

I'm not sure exactly -- I'll have to load it to find out -- I'll get back
to you with some more details.. Thanks for the heads-up though -- at least
it's a place to start looking.

What version of Seaside for current version of Magritte?

Lukas --

Just to make sure I'm not trying to plug together apples & oranges, what
version of Seaside does the latest version of Magritte work with? 
Ultimately, I'm trying to avoid the Seaside 2.6 tree and move into either
2.7 or perhaps even 2.8 and wanted to check.. I didn't see anything
indicating this on the web page, but may have missed it perhaps.

Thx!

That's exactly the spot.  The #resignalAs: is causing VW some heartburn.

I don't exactly remember why I copy the exception there. That seems  
rather strange and presumably causes VW to end up in an infinite  
recursion.

Please try with the following code that works -- as far as I can see  
right now -- well in Squeak:

visitDescription: aDescription
	"Validate the current object using aDescription within an exception  
handler to avoid running further tests that might cause error-cascades."

	aDescription isVisible ifFalse: [ ^ self ].
	[ self validate: self object using: aDescription ]
		on: MAValidationError
		do: [ :err | err beResumable; pass ]

#invalidDispatcher error - causes an improper store into indexable object

Hi,

in my image, PRPierMain>>invalidDispatcher: causes an improper store 
into indexable object
WAResponse internalError: 'bla bla'
executing the last line causes the error...in 
SeasideSupportPlatform>>walkbackStringFor:
is it because error are not meant to be a string (anymore) ? ... don't 
know how to fix...

I use the last seaside and pier version.

Cédrick

I am using it with 2.8. It should also work with 2.7 as far as I  
know, but I didn't try.
