Ahh, I already found some the _keyAssociations method while browsing for content assist to the WOComponent.

When I tried it out, this is what I got.

If you catch and dig down in that exception you might get some explanation, but...


Or should I try it out somewhere else? In Debugging mode? Learning...

public PrintTickets(WOContext context) {
		super(context);
		System.out.println("[ into printticket]\n");
		System.out.println(associations());
}


BTW, this is what I got in 5.4.3 with the original code: it complains about "\ufeff" (65279). Any idea?

<zero width no break space>
Looks like the first character of your WOD is not acceptable. Maybe a UTF-16 char in a UTF-8 defined file?






I replaced the whole wod file with a new one (copy and paste). Still the same error.

The briljant and cool as ice associations() class does not give any hints either. All I get is a null error. What is it supposed to be showing, and when?


I noticed that another wod file, with another component, seemed to produce very strange content: there was a word in that wod file: "Beëindig Verkoop", that got into the webbrowser as:
<pastedGraphic.png>


It seems odd, Safari did not pick up that it was UTF-8 encoded. But I guess that is not the core of this problem.

What does the WOO file say the encoding is? What does Eclipse think it is? Any chance these are really UTF-16?

Chuck



sh-3.2# file *
PrintTickets.html: ASCII text, with very long lines
PrintTickets.wod:  ASCII text
PrintTickets.woo:  ASCII text


Eclipse (via navigator):
PrintTickets.wo : UTF-8, inherited from container
PrintTickets.html : UTF-8, inherited from container
PrintTickets.woo : UTF-8, determined from content
PrintTickets.wod : UTF-8, determined from content

PrintTickets.woo:
{
	"WebObjects Release" = "WebObjects 5.0";
	encoding = "UTF-8";
	variables = {};
}

I opened the files in SubEthaEdit and TextWrangler, and they both agreed on UTF-8 for all the files.

(Had the error in 5.4.3 and 5.3.3, latest WOLips and Wonder)

I had an error in an old project, so I wanted to fix that, but while testing it, somewhere else in the code I suddenly got this error that seems to be saying it can not find a component called PrintTicketForm, which is a WOForm in the Component PrintTickets.wo.

I looked at it, and looked at it. It is there, I can see it, I looked at UTF gremlins, none around.

If it makes you feel any better, I can see it to. :-) Try logging out associations() from PrintTickets and see if that matches the WOD or produces a more useful error.


What do you mean by associations? How do I provoke these things to come up?
<pastedGraphic.png>


The second one seems not too good a reference...


The only thing that I can imagine is that the PrintTickets component does not like to be an extension of another component (WebStoreComponent) which is an extension of WOComponent.

I do multi-level inheritance like that all the time, that should not be the problem.


Does anybody know any other reason why the webobjects parser is not able to find this, but used to like this in the old days (let's say the end of 2006?). 

I can't think of anything.
