Re: Witango-Talk: Upgrading from Witango 5.0 to Witango 5.5 - Syntax Errors

Thu, 08 Feb 2007 10:31:38 -0800

When exactly were we as developers told not to use the @@ shorthand? I missed that update and have been using it for the past 8 years. I just checked with the 5.5 Programmer's Guide and it still gives examples using that shorthand. 

Just curious...

Due to unpredictable behavior related to the interpretation of the @@ notation in Tango, we stopped using it a long time ago. I can't comment on 5.0 vs 5.5. support, because it's something that I started getting away from back on Tango 2000

    Adam,

    I have no comments for or against the ( instead of [ trick - but if
    it works that certainly helps, doesn't it? I would guess it has more
    to do with the code shorthand not being handled properly though -
    and could also be handled by a search and replace. I always write
    things out a bit more, like:

    <@var request$exampleArray[<@var request$rowCounter>,FieldName]>

    You might try doing a replace on one file and see if it works. It's
    certainly more 'correct' than using the parentheses, although I
    really don't know if that's going to help.

    Good luck with it!

    Thanks for the info. Jason.  I've actually figured out a
    work-around, but it's not one that I feel comfortable implementing.
The issue seems to occur in IF actions (not metatags), I've pasted 
    examples below:
Non-working example in 5.5 - working in 5.0: 
    @@request$exampleArray[@@request$rowCounter,FieldName]
Working example in 5.5 - not tested in 5.0: 
    @@request$exampleArray(@@request$rowCounter,FieldName)
You'll notice that all I've done to fix the issue is replace the 
    [] brackets with () parenthesis.  I've checked Witango
    documentation, this is not correct syntax, but works none-the-less.
It seems like the Witango interpreter is getting hung up on [] 
    used in extracting array data in IF actions... maybe related to
    the CDATA encapsulators?
Has anyone encountered an issue like this? Can someone from the 
    Witango team provide any insight?  This issue affects around 20%
    of our applications and has thrown a wrench into our conversion
    timeline!
Our environment is a Windows 2000 Advanced Server using Witango 
    5.5.20 and a Pervasive 9.5 Database.

    Adam,

    The only major 'gotcha' I encountered was making sure that all
    places where I used 'encoding=multilinehtml' were change to
    'encoding=multiline'. Otherwise I don't think I had any problems.
    Things to look at though would also be customizations you may have
    made to the witango.ini file - like default scope for variables.

    It would help to know the server platform though, and any other
    details you can think of. If you look at two or three of the files
    that are producing errors you might find a common thread.

    Hope that helps-

    Jason

    Hello everyone,
We're in the process of upgrading our Witango Server from 5 to 
    5.5 and we've encountered an odd issue.  Applications that work
properly in the 5 environment are throwing Syntax errors. Specifically, it deals with 'Missing closing brackets' and 'Missing quote at the end of the statement' kinds of problems. Again, these applications work without issue in the 5 environment. Has anyone encountered something like this? Am I missing a 
    configuration option?  Is there a conversion application I should
    run against the Witango 5 applications to bring them up to 5.5?
Any help is greatly appreciated! Thanks,
