[Xerte-dev] Re: Problem with textDrawing (Flash) page in XOT

Mon Nov 26 16:40:00 GMT 2012

I found this while almost fully through developing textDrawing model. I think for the Easter release I'll work towards getting this working. If we can stay at IE8 compatibility then that’s fine by me...

Quite. IE8 is bad enough, but if you run XP you can't run IE9...

Well yes we have the same situation but everything can't be held back just so the NHS can access stuff...

At least now they can use iPads in placement...

At least you get IE9. IN the hospital it's [crackle of thunder and lightning] IE6.

Yes, I'm happy with IE8 for now but it's definitely something that we should look at upping to IE9, perhaps for the next release. IE is a terrible browser though and even IE8 messes up the Xenith interface slightly at the bottom which I've had a bit of a look at and not been able to remedy yet. But like you and many other institutions for some unknown loyalty to Microsoft, IE8 is was our standard browser, and now it's IE9...

IE8 is the recommended and supported browser here, that might be it, though more likely it was to try and get as much of the functionality working in IE as possible.

Hi Ron,

Are you sure you cleared the cache? I can see page 2 in IE but it does a poor job in this instance since it falls back to the available HTML4. I have to ask Fay if there is a reason that we are forcing IE8 compatibility in Xenith because we'll never be able to make use of <canvas> in IE9.

Have attached a screenshot of how page 2 appears for me...

Hi John
your updated file is in place now - seems to have fixed the Chrome issue but still not seeing page 2 in IE even after clearing cache etc.
Same links apply
View the flash version http://vle.jisctechdis.ac.uk/xot/play.php?template_id=150
View the html5 version http://vle.jisctechdis.ac.uk/xot/play_html5.php?template_id=150 page 2 is empty HTH Ron

Hi Ron,

Thanks for that, you managed to choose the worst text string possible!! Usually you need to be very careful about using parseInt or Math.round to convert strings to numbers when you do calculations in JavaScript. This time though I was using .split(' ') on the passed in text string but JS was very unhelpfully just casting the text to a number and then it obviously couldn't find the .split method...

I've fixed it in SVN now and it seems to be working please try that if you get a moment and see if it's fixed...

Yes I do mean that window and as I said anecdotally I don't remember this ever happening prior to 1.8 and it's not consistent now, but on occasions the browse window has appeared below other windows.

BTW John - I hadn't updated the Techdis install with the html 5 model until now and there seems to be some odd stuff going on...
e.g. In IE9 via the html5 version I see page 1 & 3 but not page 2 View the flash version http://vle.jisctechdis.ac.uk/xot/play.php?template_id=150
View the html5 version http://vle.jisctechdis.ac.uk/xot/play_html5.php?template_id=150 page 2 is empty

In Chrome it's the reverse I see page 2 but not 1 & 3 Same in Firefox and Safari

You mean the native windows browse file dialog? It's not to the front? I've never even thought you could control it, I thought it was always to the fore (and modal?)

Hi John
I just tested this and shared the file with your account on the Techdis install.
I can't make it lose any lines etc and importing an image works fine too.
e.g.
http://vle.jisctechdis.ac.uk/xot/play.php?template_id=150
page 1 I created as a test file for you previously, page 2 I just created.
All seems to work fine.

Having said that except for a more general point not unique to this page type that I've noticed recently and this is anecdotal rather than 100% certain..

I'm fairly sure that previously (pre 1.8) when using a page type that allowed for browsing and uploading media the browse window always appeared on top of all other windows. Now the browse window often appears below the editor window and so can easily be missed. I'm not sure if this is a client issue e.g. when using IE I'm now using IE9 rather than IE8. I don't have time to test this theory with other browsers at the moment but is it possible that when you've been testing adding an image the browse window has been behind others?

HTH
Ron

AFAIK, the code in the DRAW class hasn't changed, nor has the code in the drawing editor? At least, I've not changed it...

Hi,

Further to my last message about the image button not working, now there is a more serious problem with things disappearing. If you draw some lines and then go to 'Save Drawing' on the menu the last 1 (or few) of the lines that were drawn just disappear! Can anyone else replicate this? It's only been doing this recently so i'm assuming its due to one of the recent updates that one of you did and that someone will know where the problems lie?
