UPDATE
I was experiencing inconsistencies with Firestore's dot notation and have learned that we must use literal notation when using the setData operation and can use dot notation when using the updateData operation.
The following operation was ignoring dot notation:
...setData(
["someMap.\(someId)": FieldValue.increment(Int64(-1))]
, forDocument: Firestore.firestore().collection("someDocument").document(userId), merge: true)
someMap: ["x34JF2ko0sPLnbfoijw": 1] // not decremented
someMap.x34JF2ko0sPLnbfoijw: -1 // instead, new number field created
To remedy the problem, we must simply use literal notation:
...setData(
["someMap": [someId: FieldValue.increment(Int64(-1))]
, forDocument: Firestore.firestore().collection("someDocument").document(userId), merge: true)
Nothing has changed with dot notation, but it apparently doesn't work with setValue(). As far as I can see, it's only documented to work with updateData() - you can see examples in that link to the documentation.
So, what you will have to do if you want to update that nested field is something like this:
transaction.setData(
[ "interactionCounts.\(eventId)": FieldValue.increment(Int64(-1)) ],
forDocument: Firestore.firestore().collection("trackers").document(userId)
)
I don't do swift programming, but I confirmed that similar code operates correctly for nodejs update() vs. set() with merge.
If you are absolutely certain that this worked with setData() in the past, I recommend you file an issue with the iOS SDK.

On my process, I have a variable that is an array of objects similar to the following:
"llista-finques" : [
{
"FIN_ID": "H10",
"FIN_NOMBRE": "PLUTO VIVIENDAS",
"FIN_PROPIETARIO": "H10",
"FIN_LINIA_NEGOCIO": "Horizontal"
},
{
"FIN_ID": "H11",
"FIN_NOMBRE": "PLUTO PARKING",
"FIN_PROPIETARIO": "H11",
"FIN_LINIA_NEGOCIO": "Horizontal"
},
{
"FIN_ID": "H12",
"FIN_NOMBRE": "PINTO VIVENDES",
"FIN_PROPIETARIO": "H12",
"FIN_LINIA_NEGOCIO": "Horizontal"
},
{
"FIN_ID": "H16",
"FIN_NOMBRE": "ZURUBANDO",
"FIN_PROPIETARIO": "H16",
"FIN_LINIA_NEGOCIO": "Horizontal"
} ......
I am trying to create a Calculated Propery in one of my forms that needs to create a subset of this array filtering by object property. In order to do so, I was hoping to use the following javascript for the calculated field:
return this.llista-finques.filter(finca => {return finca.FIN_PROPIETARIO === this.Id_client});
For some reason this code produces no result, and after many tests, I have arrived at the conclussion that the variable "this.llista-finques" is simply not accessible from the script, although it is available in the process data.
If I change the Calculated Property script to simply return the value of the variable as bellow:
return this.llista-finques;
or even someting that simply should return a string:
return this.llista-finques[0].FIN_ID
the calculated property produces no result.
If I do exaclty the same with any of the other process variables that are not arrays of objects the calculated property seems to work correctly.
Al the testing I have done is using the screen preview debuging tools of Processmaker 4.
Is there a limitation on the kind of variables I can use for calculated properties? Is this a processmaker bug?
This is embarassing ... after testing and testing and testing I figured out that the problem was due to the name of the variable I was using. Can't use a name with the character '-' ....
Once I corrected the variable name it all worked as expected.
I have a list of elements (OData set) and use a binding to show this list.
One field is for a quantity value and this value could sometimes need some decimal places.
The requirement is: only show that amount of decimal numbers that is also available in the OData service.
Annotation techniques can't be used.
I 'hacked' something that is misusing a formatter to update the type of a binding. But this is 'a hack' and it is not possible to convert it to XML views. (The reason is a different handling of the scope the formatter will be called).
So I am searching for a working solution for XML views.
The following code would not work but shows the issue:
new sap.m.Input({ // looking for an XML solution with bindings
value: {
path: "Quantity",
type: new sap.ui.model.type.Float({
// formatOptions
maxFractionDigits: "{QuantityDecimals}",
// ...
}, {
// constraints
minimum: 0
}),
// ...
}
});
The maxFractionDigits : "{QuantityDecimals}" should be "dynamic" and not a constant value.
Setting formatOptions and constraints dynamically in XML (via bindings or a declared function) is unfortunately not (yet) supported. But IMHO this is a valid enhancement request that app developers would greatly benefit from, since it encourages declarative programming.
I already asked for the same feature some years ago but in a comment at https://github.com/SAP/openui5/issues/2449#issuecomment-474304965 (See my answer to Frank's question "If XMLViews would allow a way to specify the dynamic constraints as well (e.g. enhanced syntax), would that fix the problem?").
Please create a new issue via https://github.com/SAP/openui5/issues/new with a clear description of what kind of problems the feature would resolve and possibly other use cases (You can add a link to my comment). I'll add my 👍 to your GitHub issue, and hopefully others too.
I'll update this answer as soon as the feature is available.
Get your dynamic number from your model and store it in a JS variable.
var nQuantityDecimals = this.getModel().getProperty("/QuantityDecimals");
new sap.m.Input({
value : {
path : "Quantity",
type : new sap.ui.model.type.Float({
maxFractionDigits : nQuantityDecimals,
source : {
groupingSeparator: ",",
decimalSeparator: ".",
groupingEnabled: false
}
}, {
minimum:0
})
}
}),
I'm developing an app using Grails. I want to get length of array.
I got a wrong value. Here is my code,
def Medias = params.medias
println params.medias // I got [37, 40]
println params.medias.size() // I got 7 but it should be 2
What I did wrong ?
Thanks for help.
What is params.medias (where is it being set)?
If Grials is treating it as a string, then using size() will return the length of the string, rather than an array.
Does:
println params.medias.length
also return 7?
You can check what Grails thinks an object is by using the assert keyword.
If it is indeed a string, you can try the following code to convert it into an array:
def mediasArray = Eval.me(params.medias)
println mediasArray.size()
The downside of this is that Eval presents the possibility of unwanted code execution if the params.medias is provided by an end user, or can be maliciously modified outside of your compiled code.
A good snippet on the "evil (or lack thereof) of eval" is here if you're interested (not mine):
https://javascriptweblog.wordpress.com/2010/04/19/how-evil-is-eval/
I think 7 is result of length of the string : "[37,40]"
Seems your media variable is an array not a collection
Try : params.medias.length
Thanks to everyone. I've found my mistake
First of all, I sent an array from client and my params.medias returned null,so I converted it to string but it is a wrong way.
Finally, I sent and array from client as array and in the grails, I got a params by
params."medias[]"
List medias = params.list('medias')

Bonjour, Hello,
I'm making this delphi application that I use to create word documents. I'm done with basic word operations (create/save, text, tables..etc).
What I need to do is to insert Page Numbers of headings as Cross Reference in the text. Something like :
"... and the process works as explained on page 23..."
where page number is a hyperlink to a heading. When I recorded a Macros in word it looks like:
Selection.InsertCrossReference ReferenceType:="Heading", _
ReferenceKind:=wdPageNumber, ReferenceItem:="49", InsertAsHyperlink:=True _
, IncludePosition:=False, SeparateNumbers:=False, SeparatorString:=" "
What would be the equivalent in Delphi please?
Thanks in advance!
Arjun.
Even when you're using Late Binding you still need to provide all of the parameters in the same order as the original declaration.
expression.InsertCrossReference(ReferenceType, ReferenceKind, ReferenceItem,
InsertAsHyperlink, IncludePosition, SeparateNumbers, SeparatorString)
If you aren't using a parameter then you can replace it with EmptyParam.
So I think your code will be:
Selection.InsertCrossReference('Heading', 7, '49', True, False, False, ' ');
(I think that wdPageNumber's value is 7).
Following on from this question on whitelisting HTML tags, I've been experimenting with Jeremy Wall's go-html-transform. In the hopes of improving searchable documentation I'm asking this here rather than pestering the author directly... hopefully this isn't too tool-specific for SO.
App Engine, latest SDK. Post.Body is a []byte. This works:
package posts
import (
// ...
"html/template"
"code.google.com/p/go-html-transform/html/transform"
"code.google.com/p/go-html-transform/h5"
)
// ...
// Pre-process post body, then return it to the template as HTML()
// to avoid html/template's escaping allowable tags
func (p *Post) BodyHTML() template.HTML {
doc, _ := transform.NewDoc(string(p.Body))
t := transform.NewTransform(doc)
// Add some text to the end of any <strong></strong> nodes.
t.Apply(transform.AppendChildren(h5.Text("<em>Foo</em>")), "strong")
return template.HTML(t.String())
}
Result:
<strong>Blarg.<em>Foo</em></strong>
However, if instead of AppendChildren() I use something like the following:
t.Apply(transform.Replace(h5.Text("<em>Foo</em>")), "strong")
I get an internal server error. Have I misunderstood the use of Replace()? The existing documentation suggests this sort of thing should be possible.
Running your transform code outside of App Engine, it panics and you can see a TODO in the source at that point. Then it's not too much harder to read the code and see that it's going to panic if given a root node.
