I have many input fields in Orbeon in Form builder as war1, war2 , war3, and not all fields have to be filled. I want to make a sum of this fields (I can't make them repeatable because I want to reset it via web service), but when some of the fields are empty, the sum doesn't display. Using an initial value doesn't resolve the problem because I want to set values via a web service, and sometimes the values returned by the service are empty string.
Assuming your fields are named war1, war2, war3, use:
sum(($war1, $war2, $war3)[string() castable as xs:decimal], 0.0)
And for some background on this, see the blog post Formulas for summing values, done right, which is exactly about this topic. (The very fact that there is a blog entry about this tells you that this is rather subtle, which makes your question all the more justifiable.)

I want to fill a Repeated grid with value from a checkbox.
User would select multiple items from a checkbox then hit a button to add the required number of rows and set the value of a field in each iteration according to what was checked
I would need something like a foreach checked value : run this code
I'm having a hard time finding documentation about this kind of Xforms. I did find some info about Iterate and Iterator that seems promising but i failed to make that work.
I was able to add the required number of row to my grid but then im not sure how to use xf:setvalue set the value of each row.
Any help appreciated.
I think a combination of the iterate attribute to create a loop, the xxf:split() function to get the selected values as a sequence you can iterate on, and xf:insert to create elements will do the trick. See this example, which does the following:
And here is an example which does the same, but for a form created with Form Builder. In this case, the result is as follows:
I have a problem when it comes to suming values from a repeated section. Specifically, when I have a repeated section in the orbeon builder with a control that has a value I can easily sum the values of these sections in a different control using sum($control-1) - in the calculated value. When inputing values in the form preview the sum is correct in my control with the summed value.
Unfortunately, when I add a section using the +Insert Below button in the form preview while testing the form the sum() function doesn't work anymore. In the control with this calculated value nothing is shown. Is there a different way to get the sum of values from repeated sections or is this a bug in orbeon?
Once you add a new section while testing the form the sum() function doesn't work anymore, because it adds a empty element to the node-set.
In XPath, when using the sum function, the value of each node is determined by trying to converting it to a number (number()), if there is a empty value, it's gonna convert to NaN, thus in the control with this calculated value nothing is shown by Orbeon.
A different way that would work would be to use the expression like: sum($control-1[text()]) . This way you are testing if the node has content before trying to sum it, so it's always gonna work.
Say we have a form built in Form Builder that consists of one repeat, containing two controls: a text input (id) and a text output (name). In addition we have a populated database table with two columns, id & name.
This is how the form should behave: the user can add as many rows as needed. In each row, when an ID is entered for a row, a database service is called which looks up name for the given id, and the Name text output is populated on that row.
It's easy to get such a scheme to work if a repeat isn't involved, but with the repeat, it seems that Orbeon doesn't know from which row to get the id parameter value, or to set the returned name value. Any options for accomplishing this that would work in Form Builder?
Apparently the answer is "no" for 4.4 but forthcoming v4.5 should introduce actions that work with repeats (see here and here).
When choosing 'Add' in CRUD, how best to generate a list of choices to pick from a dropdown?
For U/update - just display what's there...
The field contents starts with a letter, followed by five numeric digits:{A-I,K-N,Z}#####
Each letter has a different 'max' value for the numeric part.
So when adding a new record, I'd like to offer a listbox with one of each letter and that letter's highest numeric value + 10.
So, if the max 'A' as A00120, and max 'B' B00030 (etc) the listbox would have A00130 and B00040.. etc
Save the user having to figure out which is 'next' when generating a new record.
? Thanks,
Mark
This time I'll not be able to come up with ready to use solution, but I must say - everything is possible with ATK4. You just have to customize and extend it to fit your needs :)
Speaking about your question above - I guess you have to split it in multiple parts.
First part is about how to show select box on Create and readonly or disabled field on Update. I guess you can make some custom Form field or pin some action to existing Form Field hook. Not sure exactly what's better in this case.
Second one is about data structure. I believe that this field actually should be 2 fields in DB and maybe (only maybe) merged together in ATK model with addExpression() just for user interface needs to display these 2 fields as one field easily in UI. Maybe such concatenated field will be useful also for searching, but definitely not as only one field stored in DB. Imagine how hard it'll be for DB engine to find max value if such field. Store it like type = letter, num = number and then search like SELECT max(num)+10 FROM t WHERE type='A'
Finally Third part is about how to generate this next number. I read your question 3 times and came to conclusion that actually you don't have to show this +10 numeric value in UI at all if it's hardly predefined anyway. Actually that'll not work correctly if this will be multi-user system which I guess it will. Instead just show simple select box with letters {A-I,K-N,Z} and calculate this next value exactly before inserting data in DB. That can be done using models insert hook. This will be much more appropriate solution and will be better for UI and also more stable because calculated in model not incorrectly in UI part.
I have 3 fields, Action1, Action2 and Action3 contained in one report. Each Action field is selected from the same list of values. I would like to graph a count of these values by the value of the field and not field itself. I need one graph and not one graph per Action field. I have tried to combine the field values into an array in the details section, but the report shows the concatenated string values "Action1, Action2, Action3', as a single value in the graph. I tried to graph using "on change of", but it will only allow 2 fields and not 3. Is there a way to count these values regardless of the Action field where they are found?
I have been working with Crystal for years, but can't figure this out for whatever reason.
I was never able to find a solution to this issue inside of Crystal Reports itself. What I ended up doing was creating a stored procedure in SQL to use as the data source. In the stored procedure I basically performed a cross join such that there was only 1 Action returned per record. In CR I then was able to summarize the Action field values.
