xpages #IsMember function in dialog list item values - xpages

Based on this XPages adding #Formulas in dialogList, my dialogList1 takes values from two concatenated views: a and b.
There is another dialogList2, which is rendered depending if the dialogList1 value is null or not, whose values should be like this:
dialogList1.value is from a => dialogList2.choices should be only from b
dialogList1.value is from b => dialogList2.choices should be only from a
I tried:
// Contr.txt_particontractcv_1 - is the value binded by dialogList1
var dbname = session.getServerName() + "!!" + "mynsf.nsf";
//var a = #Unique(#DbColumn(dbname, "vwNumeCompanii", 0)).sort();
//var b = #Unique(#DbColumn(#DbName(),"vwA",0));
//return a.concat(b);
if ( #IsMember(Contr.txt_particontractcv_1,#Unique(#DbColumn(#DbName(),"vwA",0))))
{ return #Unique(#DbColumn(dbname, "vwNumeCompanii", 0)) }
else
{ return #Unique(#DbColumn(#DbName(),"vwA",0)) }
but the dialogList2 is taking values only from vwA ( from b ) ... I think I'm missing something. Thanks for your time.

Contr.txt_particontractcv_1 cannot be used in SSJS. Dot notation works in LotusScript but not SSJS or Java because Java's runtime is not proprietary and has not been extended that way. That is why Contr.getItemValueString("txt_particontractcv_1") is required.
Some SSJS global variables allow dot notation to be used, e.g. sessionScope. But that is because it is based on a Map, so sessionScope.myProperty can only map to sessionScope.get("myProperty"). The Domino Document class does not extend the Map interface (that's one of the enhancements of the OpenNTF Domino API), so dot notation doesn't know whether to use getItemValue(), getItemValueString(), getItemValueDateTimeArray() etc.
This is also why best practice for scoped variables is also to use e.g. sessionScope.get("myVar"). When it comes to moving to Java, you will not be able to use dot notation, you will have to use the relevant method. So working that way in SSJS fosters good habits for the future.

Yep, I just modified Contr.txt_particontractcv_1 to Contr.getItemValueString("txt_particontractcv_1") and, now, it works.`

Use JOOQ Multiset with custom RecordMapper - How to create Field<List<String>>?

Suppose I have two tables USER_GROUP and USER_GROUP_DATASOURCE. I have a classic relation where one userGroup can have multiple dataSources and one DataSource simply is a String.
Due to some reasons, I have a custom RecordMapper creating a Java UserGroup POJO. (Mainly compatibility with the other code in the codebase, always being explicit on whats happening). This mapper sometimes creates simply POJOs containing data only from the USER_GROUP table, sometimes also the left joined dataSources.
Currently, I am trying to write the Multiset query along with the custom record mapper. My query thus far looks like this:
List<UserGroup> = ctx
.select(
asterisk(),
multiset(select(USER_GROUP_DATASOURCE.DATASOURCE_ID)
.from(USER_GROUP_DATASOURCE)
.where(USER_GROUP.ID.eq(USER_GROUP_DATASOURCE.USER_GROUP_ID))
).as("datasources").convertFrom(r -> r.map(Record1::value1))
)
.from(USER_GROUP)
.where(condition)
.fetch(new UserGroupMapper()))
Now my question is: How to create the UserGroupMapper? I am stuck right here:
public class UserGroupMapper implements RecordMapper<Record, UserGroup> {
#Override
public UserGroup map(Record rec) {
UserGroup grp = new UserGroup(rec.getValue(USER_GROUP.ID),
rec.getValue(USER_GROUP.NAME),
rec.getValue(USER_GROUP.DESCRIPTION)
javaParseTags(USER_GROUP.TAGS)
);
// Convention: if we have an additional field "datasources", we assume it to be a list of dataSources to be filled in
if (rec.indexOf("datasources") >= 0) {
// How to make `rec.getValue` return my List<String>????
List<String> dataSources = ?????
grp.dataSources.addAll(dataSources);
}
}
My guess is to have something like List<String> dataSources = rec.getValue(..) where I pass in a Field<List<String>> but I have no clue how I could create such Field<List<String>> with something like DSL.field().
How to get a type safe reference to your field from your RecordMapper
There are mostly two ways to do this:
Keep a reference to your multiset() field definition somewhere, and reuse that. Keep in mind that every jOOQ query is a dynamic SQL query, so you can use this feature of jOOQ to assign arbitrary query fragments to local variables (or return them from methods), in order to improve code reuse
You can just raw type cast the value, and not care about type safety. It's always an option, evne if not the cleanest one.
How to improve your query
Unless you're re-using that RecordMapper several times for different types of queries, why not do use Java's type inference instead? The main reason why you're not getting type information in your output is because of your asterisk() usage. But what if you did this instead:
List<UserGroup> = ctx
.select(
USER_GROUP, // Instead of asterisk()
multiset(
select(USER_GROUP_DATASOURCE.DATASOURCE_ID)
.from(USER_GROUP_DATASOURCE)
.where(USER_GROUP.ID.eq(USER_GROUP_DATASOURCE.USER_GROUP_ID))
).as("datasources").convertFrom(r -> r.map(Record1::value1))
)
.from(USER_GROUP)
.where(condition)
.fetch(r -> {
UserGroupRecord ug = r.value1();
List<String> list = r.value2(); // Type information available now
// ...
})
There are other ways than the above, which is using jOOQ 3.17+'s support for Table as SelectField. E.g. in jOOQ 3.16+, you can use row(USER_GROUP.fields()).
The important part is that you avoid the asterisk() expression, which removes type safety. You could even convert the USER_GROUP to your UserGroup type using USER_GROUP.convertFrom(r -> ...) when you project it:
List<UserGroup> = ctx
.select(
USER_GROUP.convertFrom(r -> ...),
// ...

PDFTron: What is the proper way to find date fields in a PDF form

[PdfTron 5.2]
I have a PDF form with text and date fields. I want to find the date fields.
I can get the actions of the field with getActions().
field.getActions()
returns
{"F":[{"yc":"JavaScript","Gt":"AFDate_FormatEx(\"dd.mm.yyyy\");"}],
"K":[{"yc":"JavaScript","Gt":"...);","ey":null}]}
As you can see, the date is in actions.F[0].Gt. But checking actions.F[0].Gt
for "AFDate" seems wrong, that's too low-level.
Is there a better API function to find out, that I have a date field?
Thank you.
You are correct. The Gt property is obfuscated and minified which is volatile and not meant to be used. If you require an API, you should refer to our documentation. Everything should be available there except a few (one of which will be used below), but feel free to contact us if you do need help!
Unfortunately, there is no API currently to get that type. From my limited understanding, the "type" of a field is determined by the attached actions and not simply a specific type or flag. This suggests all fields are just text fields with special formatting actions to make it look and feel like its a date or numeric field.
In this case, you will have to check the formatting action (F) as you have already noticed for the date formatting function (AFDate_FormatEx). To get the JavaScript from that action, you should use the javascript property on the action which was not in the documentation. However, you can see it if you console log the action.
Here is an example:
const dateActionJs = /.+:"AFDate_FormatEx\(.*/;
instance.docViewer.on('annotationsLoaded', () => {
const annotations = annotManager.getAnnotationsList();
annotations.forEach(annot => {
const actions = annot.getField().getActions();
if (actions.F && actions.F[0] && actions.F[0].javascript && dateActionJs.test(actions.F[0].javascript)) { // F = Format Action
console.log('Found Date');
}
});
});
Let me know if this helps!
EDIT: You can search for AFDate instead of AFDate_FormatEx which will be sufficient.

getting a list of forms that contain a specified field, is there a better method

The following code is a script object on an XPage in it I loop through an array of all the forms in a database, looking for all the forms that contain the field "ACIncludeForm". My method works but it takes 2 - 3 seconds to compute which really slows the load of the XPage. My question is - is there a better method to accomplish this. I added code to check to see if the sessionScope variable is null and only execute if needed and the second time the page loads it does so in under a second. So my method really consumes a lot of processor time.
var forms:Array = database.getForms();
var rtn = new Array;
for (i=0 ; i<forms.length; ++i){
var thisForm:NotesForm = forms[i];
var a = thisForm.getFields().indexOf("ACIncludeForm");
if (a >= 0){
if (!thisForm.isSubForm()) {
if (thisForm.getAliases()[0] == ""){
rtn.push(thisForm.getName() + "|" + thisForm.getName() );
}else{
rtn.push(thisForm.getName() + "|" + thisForm.getAliases()[0] );
}
}
}
thisForm.recycle()
}
sessionScope.put("ssAllFormNames",rtn)
One approach would be to build an index of forms by yourself. For example, create an agent (LotusScript or Java) that gets all forms and for each form, create a document with for example a field "form" containing the form name and and a field "fields" containing all field names (beware of 32K limit).
Then create a view that displays all these documents and contains the value of the "fields" field in the first column so that each value of this field creates one line in this view.
Having such a view, you can simply make a #DbLookup from your XPage.
If your forms are changed, you only need to re-run the agent to re-build your index. The #DbLookup should be pretty fast.
Place the form list in a static field of a Java class. It will stay there for a long time (maybe until http boot). In my experience applicationScope values dissappear in 15 minutes.

How to maintain counters with LinqToObjects?

I have the following c# code:
private XElement BuildXmlBlob(string id, Part part, out int counter)
{
// return some unique xml particular to the parameters passed
// remember to increment the counter also before returning.
}
Which is called by:
var counter = 0;
result.AddRange(from rec in listOfRecordings
from par in rec.Parts
let id = GetId("mods", rec.CKey + par.UniqueId)
select BuildXmlBlob(id, par, counter));
Above code samples are symbolic of what I am trying to achieve.
According to the Eric Lippert, the out keyword and linq does not mix. OK fair enough but can someone help me refactor the above so it does work? A colleague at work mentioned accumulator and aggregate functions but I am novice to Linq and my google searches were bearing any real fruit so I thought I would ask here :).
To Clarify:
I am counting the number of parts I might have which could be any number of them each time the code is called. So every time the BuildXmlBlob() method is called, the resulting xml produced will have a unique element in there denoting the 'partNumber'.
So if the counter is currently on 7, that means we are processing 7th part so far!! That means XML returned from BuildXmlBlob() will have the counter value embedded in there somewhere. That's why I need it somehow to be passed and incremented every time the BuildXmlBlob() is called per run through.
If you want to keep this purely in LINQ and you need to maintain a running count for use within your queries, the cleanest way to do so would be to make use of the Select() overloads that includes the index in the query to get the current index.
In this case, it would be cleaner to do a query which collects the inputs first, then use the overload to do the projection.
var inputs =
from recording in listOfRecordings
from part in recording.Parts
select new
{
Id = GetId("mods", recording.CKey + part.UniqueId),
Part = part,
};
result.AddRange(inputs.Select((x, i) => BuildXmlBlob(x.Id, x.Part, i)));
Then you wouldn't need to use the out/ref parameter.
XElement BuildXmlBlob(string id, Part part, int counter)
{
// implementation
}
Below is what I managed to figure out on my own:.
result.AddRange(listOfRecordings.SelectMany(rec => rec.Parts, (rec, par) => new {rec, par})
.Select(#t => new
{
#t,
Id = GetStructMapItemId("mods", #t.rec.CKey + #t.par.UniqueId)
})
.Select((#t, i) => BuildPartsDmdSec(#t.Id, #t.#t.par, i)));
I used resharper to convert it into a method chain which constructed the basics for what I needed and then i simply tacked on the select statement right at the end.

Binding an edit box within a custom control to a form field programatically

I have a notes form with a series of fields such as city_1, city_2, city_3 etc.
I have an XPage and on that XPage I have a repeat.
The repeat is based on an array with ten values 1 - 10
var repArray = new Array() ;
for (var i=1;i<=10;i++) {
repArray.push(i) ;
}
return(repArray) ;
Within the repeat I have a custom control which is used to surface the fields city_1 through city_10
The repeat has a custom property docdatasource which is passed in
It also has a string custom property called cityFieldName which is computed using the repeat
collection name so that in the first repeat row it is city_1 and in the second it is city_2 etc..
The editable text field on the custom control is bound using the EL formula
compositeData.docdatasource[compositeData.cityFieldName]
This works fine but each time I add new fields I have to remember to create a new custom property and then a reference to it on the parent page.
I would like to be able to simply compute the data binding such as
compositeData.docdatasource['city_' + indexvar]
where indexvar is a variable representing the current row number.
Is this possible ? I have read that you cannot use '+' in Expression Language.
First: you wouldn't need an array for a counter. Just 10 would do (the number) - repeats 10 times too. But you could build an array of arrays:
var repArray = [];
for (var i=1;i<=10;i++) {
repArray.push(["city","street","zip","country","planet"]) ;
}
return repArray;
then you should be able to use
#{datasource.indexvar[0]}
to bind city,
#{datasource.indexvar[1]}
to bind street. etc.
Carries a little the danger of messing with the sequence of the array, if that's a concern you would need to dig deeper in using an Object here.
compute to javascript and use something like
var viewnam = "#{" + (compositeData.searchVar )+ "}"
return viewnam
make sure this is computed on page load in the custom control
I was never able to do the addition within EL but I have been very successful with simply computing the field names outside the custom control and then passing those values into the custom control.
I can send you some working code if you wish from a presentation I gave.
