[Xerte] Re: Decision icon repeat

[Dave Burnett]

Hi Jonathan.Thanks for looking in to that.
The issue is that in Authorware, which Julian based the flow structure of Xerte on, setting a decision icons repeat property meant it would loop through that decision icon and all attached icons that specified number of times.
It would essentially repeat the entire attached sequence of icons x times.
I know I had this issue a couple years back, and the solution was a bit obtuse, but I can't remember it or track it down in the archives.

Further to my earlier post the Branch property will also affect what happens.

The help file reads

A setting of 
'sequence', 'randomUnused', 'randomAny', or 'calculate'. 



'sequence' loops through the children of the 
decision icon in order. 


'randomUnused' loops through the children in a 
random order, until all the paths are used, or until the repeat property is 
satisfied. 


'randomAny' loops through the children until the 
repeat property is satisfied, and may visit the same child more than once. 



'calculate' allows you to route the flow into a 
particular page of the decision icon using the path property, which is zero 
based - to flow into the third page, set branch to calculate, and the path 
property to 2.
The following models use the decision icon and may give further insight into its use.

annotatedDiagram.rlm
bullets.rlm

buttonSequence.rlm
categories.rlm

columnPage.rlm
connectorMenu.rlm

customHotspots.rlm

dialog.rlm
dragDropLabel.rlm

inventory.rlm
links.rlm

list.rlm
memory.rlm

menu.rlm
perspectives.rlm

quiz.rlm
table.rlm

text.rlm
textMatch.rlm

thumbnailViewer.rlm
timeline.rlm

transcriptReader.rlm


The only one that does not set repeat-"all" in the model code is text.rlm which has repeat="1" and branch="calculate"


I don't know if this will help you to resolve your issue.


Hope it does :-)

I have taken a look at the model files to see which pages use the decision icon.

After finding that the bullets page uses the decision icon I then ran some tests

By default the decision icon in the bullets page is set to 

all
This results in the page listing every bullet.
If however you replace the repeat value in the property page with a number e.g.


3
Then only the first three bullets gets listed.
So I guess the answer is you put a number in (without any quotes) and the decision icon will run that many times.


Hope that helps.
You may find that taking a look at the bullets.rlm file in your xerte installs \pages\models\ folder will cast some light on its use.


Kind regards
Johnathan
PS sorry for the delay in replying - very busy on the Connector page documentation at the moment.

No takers?
Help says the Repeat property will take All or a number.If I use a number, nothing happens.

What goes in the property sheet of a decision icon to have it repeat a set number of times?
