Servoy Forum

Hi all,

I've this kind of code:

Code: Select all

var _myFoundset = databaseManager.getFoundSet("my_repository","my_table");
      _myFoundset.my_field = "hello"


and I obtain a warning like "the property 'my_field' is undefined for the type JSFoundset".

I wouldn't this kind of warning: the only way is to disable it from the preference?
or does exist a way to write it to avoid this warning? (I wantn't use a design form foundset)

Thanks for the help

Hi Marco,

When you use the databaseManager.getFoundSet() function you get an empty foundset so you first need to load any record(s) or create them in this foundset.

Hope this helps.

You can use jsdoc to let Servoy know what kind of foundset is in the variable:

Code: Select all

/** @type {JSFoundset<db:/my_repository/my_table>} */
var _myFoundset = databaseManager.getFoundSet("my_repository","my_table");
_myFoundset.my_field = "hello"

Then the warnings will disappear.

Ok!

Thank you all for your answers.
It will be usefull.

Ok, one last thing:

I've a MEDIA variable called "root".

At the startup a global fuction will instantiate "root" as Object()

Code: Select all

globals.root = new Object()


I use it as an Object array by:

Code: Select all

globals.root[_myCurrCollection] = new Object()


and fill its variables:

Code: Select all

globals.root[_myCurrCollection].myLength = 0;
globals.root[_myCurrCollection].myWidth = 100;
globals.root[_myCurrCollection].myCandies = 200;
globals.root[_myCurrCollection].myList = new Array()
etc..


At now it's all ok but when I point to "globals.root[_myCurrCollection].myLength" by a form-function, I obtain a warning as "undefined in javascript".

I've tried to use:

Code: Select all

/** @type {Number}  */


over the variable initialization but I suppose that it works just into the instance case.

What is the right way to solve this?

Thanks in advance.

Marco

look here:
http://wiki.servoy.com/display/public/D ... sing+JSDoc

under the section Object Type and so on

in your example globals.root looks a lot like:

Object<{{myLength :Number, myWidth :Number,myCandies :Number, myList :Array}}>

Thanks Johan!

I'll use it for any future necessity!

I've tried to follow what you have suggested and I've put for example:

As global:

Code: Select all

/** @type {Object<{{MyName:String}}>}*/
var root = new Object()

but when I save the changes it becames:

Code: Select all

/** @type {Object< MyName:String  >} */

with warning "Unknow type MyName."

Into the wiki I've found:

Code: Select all

{ {name:String, age:Number}}

so I've tried to put

Code: Select all

/** @type {{MyName:String}}  */

but after saving I obtain

Code: Select all

/** @type {MyName:String} */

with warning "Unknow type MyName".

Am I missing to do something?

Thanks

no you dont miss anything thats currently a bug in 6.0.1 (the removal of the { } )
Is already fixed for 6.0.2

Ok thanks, I'll wait for it!
