I have Ldap configureted in my project, it's very simple the settings and widgets but this Email template I can't configure because I don't know to where to start, I have tried setting it up a few times but without succesfull. I already have together with Email template, the Encryption and MxModelReflection. Someone could help me in how I to configure smtp and send emails?

How to dynamically size a Chart widget Pie chart.
Hi, I have a template grid in which I display a Pie chart for each record. This works great with the Charts widget, except for 1 thing; The total value of each Pie chart differs greatly but it is not visually visual as all Pie charts have the same size. Does anyone have an idea/trick on how to size a Pie chart dynamically. So that the sizes are in relation with each other?

Upgrade script generated not optimized
Hi Everyone We are planning to upgrade to mendix 8 from 7 and have a lot of float attributes that needs now to be converted to decimal. The upgrade script generated handle each column on its own even if they are in the same table. The problem with this is we have some very large tables with a few columns on each that mendix upgrade in the scripts. Doing one update per column at a time is very slow. We need to upgrade in a short window of time. Below is a sample of 2 columns handled separately. Is there a way mendix could generate the script more optimized like for instance see below. Generated: ALTER TABLE "BLAZE$AFFORDABILITYTRACKING" RENAME COLUMN "FIXEDPORTION" TO "5F4B4DCE0C7C49E3AE15492A691265"; ALTER TABLE "BLAZE$AFFORDABILITYTRACKING" ADD "FIXEDPORTION" number(28, 8) NULL; UPDATE "BLAZE$AFFORDABILITYTRACKING" SET "FIXEDPORTION" = CASE WHEN 1.0E20 > "5F4B4DCE0C7C49E3AE15492A691265" THEN "5F4B4DCE0C7C49E3AE15492A691265" ELSE 0 END; ALTER TABLE "BLAZE$AFFORDABILITYTRACKING" DROP COLUMN "5F4B4DCE0C7C49E3AE15492A691265"; ALTER TABLE "BLAZE$AFFORDABILITYTRACKING" RENAME COLUMN "DISPOSABLEMTHINCOME" TO "D1AE4A062D7F42DF89287C0102B09C"; ALTER TABLE "BLAZE$AFFORDABILITYTRACKING" ADD "DISPOSABLEMTHINCOME" number(28, 8) NULL; UPDATE "BLAZE$AFFORDABILITYTRACKING" SET "DISPOSABLEMTHINCOME" = CASE WHEN 1.0E20 > "D1AE4A062D7F42DF89287C0102B09C" THEN "D1AE4A062D7F42DF89287C0102B09C" ELSE 0 END; ALTER TABLE "BLAZE$AFFORDABILITYTRACKING" DROP COLUMN "D1AE4A062D7F42DF89287C0102B09C"; Optimised will look like this maybe: ALTER TABLE "BLAZE$AFFORDABILITYTRACKING" RENAME COLUMN "FIXEDPORTION" TO "5F4B4DCE0C7C49E3AE15492A691265"; ALTER TABLE "BLAZE$AFFORDABILITYTRACKING" RENAME COLUMN "DISPOSABLEMTHINCOME" TO "D1AE4A062D7F42DF89287C0102B09C"; ALTER TABLE "BLAZE$AFFORDABILITYTRACKING" ADD "FIXEDPORTION" number(28, 8) NULL; ALTER TABLE "BLAZE$AFFORDABILITYTRACKING" ADD "DISPOSABLEMTHINCOME" number(28, 8) NULL; UPDATE "BLAZE$AFFORDABILITYTRACKING" SET "FIXEDPORTION" = CASE WHEN 1.0E20 > "5F4B4DCE0C7C49E3AE15492A691265" THEN "5F4B4DCE0C7C49E3AE15492A691265" ELSE 0 END, "DISPOSABLEMTHINCOME" = CASE WHEN 1.0E20 > "D1AE4A062D7F42DF89287C0102B09C" THEN "D1AE4A062D7F42DF89287C0102B09C" ELSE 0 END; ALTER TABLE "BLAZE$AFFORDABILITYTRACKING" DROP COLUMN "5F4B4DCE0C7C49E3AE15492A691265"; ALTER TABLE "BLAZE$AFFORDABILITYTRACKING" DROP COLUMN "D1AE4A062D7F42DF89287C0102B09C"; We can manually update the generated script and run our selves but it could lead to errors in us manually updating it as we have a very large database with many tables. , and we are lazy :)

Use XPath query based on variable
Hi, I’m quite the newbie in Mendix, and I have a problem and a hard time solving it. I have created a published REST service that queries a database, retrieves a list based on a parameter, and returns it. The entire API works, but I got stuck trying to implement a filter. There’s a query parameter that can be provided with the GET call. This parameter is in an XPath query in my Retrieve from Database action. I got the filter to retrieve based on the parameter, but I want an ‘GET ALL’ function, where it completely disregards that specific XPath filter. So currently, my filters look like this: [vehicle=$vehicle] [status=$status] I can retrieve specific statuses when providing it as a parameter in my GET call. I have also set it to a default value in case it’s not provided. However, what I can’t seem to figure out, is how to retrieve ALL events for a vehicle, so leaving out the [status=$status] when the parameter ‘status=all’ is provided in the GET call. Any pointers would be great, I’m here to learn!

GROUP BY OQL Function DATEPART throws ConnectionBusRuntimeException
Hi there, I’m currently developing an abstract data layer. I use a custom Java Action for the data retrieves. I’m not sure if this issue is connected to the one I already created an issue for, but since I turned security off for the project I assume this must be something different. We use a PostgreSQL database. I’d like to perform the following (working) query in postgres to be used in OQL in Mendix to retrieve the same data. This is the working PostgreSQL query:
select
date_part('WEEK', state_leaves_draft) as category,
State as subcategory,
count(State) as value
from
"requestfulfilment$request"
group by
category,
subcategory and yields:
[{
"category" : 45,
"subcategory" : "Initiated",
"value" : 3
}]
This is correct and expected. Here an example OQL I performed which worked:
select * from RequestFulfilment.Request yields
[
{
"Number": 97,
"State_Leaves_Draft": "Tue Nov 05 22:17:25 CET 2019",
"State": "Initiated",
...
},
{
"Number": 98,
"State_Leaves_Draft": "Wed Nov 06 10:09:13 CET 2019",
"State": "Initiated",
...
},
{
"Number": 102,
"State_Leaves_Draft": "Fri Nov 08 09:49:58 CET 2019",
"State": "Initiated",
...
}
] There are more columns, but those are not relevant for this example. The data returned is correct. Here another OQL query which works
select
DATEPART(WEEK, State_Leaves_Draft) as category,
State as part
from RequestFulfilment.Request yields:
[
{
"part": "Initiated",
"category": 45
},
{
"part": "Initiated",
"category": 45
},
{
"part": "Initiated",
"category": 45
}
] I also tested the `COUNT` function as well:
select
COUNT(State) as value
from RequestFulfilment.Request yields
[{"value":3}] Now, if I put this all together and use the group by the query looks like this:
SELECT
DATEPART(WEEK, State_Leaves_Draft) as category,
State as subcategory,
COUNT(State) as value
FROM RequestFulfilment.Request
GROUP BY category, subcategory This query throws a warning and an exception:
DataStorage_QueryHandling:

Is there a way in this situation to have the drop down from reference selector to display the selected value (i.e.already selected data )in drop down as selected the next time i open the popup. below are the images attached..here i want to display selected data(i.e. already selected )reason in reason drop down .

E-mail widget and reference selector
Dear all, do we have anyone I could contact in regards to references in Mendix and email-sending? In the logs, we find two errors in regards to this: emails cannot be sent due to no email address is found (though there is always an email address linked through a reference) sending email failed to mail server I believe that catching the references within the object is not done in time and therefore, sending the email causes an error. Does anyone have experience with this specific problem or knows how to tackle it? The App was built with Mendix Pro 8.3 and with the Siemens Layout available in the private section of the App Store. Thank you in advance, Sabrina

dynamic browser page title
Currently I am having an issue with a page where the Admins can choose which title the page should have. So this page title is saved in an entity and thus I am able to retrieve it via MF, However it seems it is not possible to use a variable in the override page title to set the correct page title in the browser tab when calling the show page. Is there any way to accomplish getting this user chosen title in the browser tab so it would look like ‘AppName – Dynamic PageTitle’

XPath retrieve sometimes slow when sorted
Situation: a table with 2.5M records. We do a sorted retrieve on all objects (in this case: around 130 of them) that are associated to a certain helper object. We do that in a java action like this:
Core.retrieveXpathQuery(getContext(),//Module.Person[Module.HelperObject_Person='349113150827176554'],-1,0,{PersonDateTimeAttribute=ASC})
Core.retrieveXpathQuery(getContext(),//Module.Person[Module.HelperObject_Person='349113150827176554'],-1,0,{PersonAutoNumberAttribute=ASC}) These queries take around 35 seconds, while there is a table index on both PersonDateTimeAttribute and PersonAutoNumberAttribute. Now consider the following, doing a similar retrieve but sorted on several attributes of an associated object:
Core.retrieveXpathQuery(getContext(),//Module.Person[Module.HelperObject_Person='349113150827176554'],-1,0,{Module.Person_Address/Module.Address/Zipcode=ASC, Module.Person_Address/Module.Address/Street=ASC, Module.Person_Address/Module.Address/HouseNr=ASC}) This (more complex, it seems) query takes 54 milliseconds. Why are the first queries so slow? How can we improve these?
