After having positioned the ruler on the trend view, sometimes the values displayed in the Y value column of the value table are followed by "[u.]" or "[i.]"; what do these mean?
Late answer, but from the fine help
("WinCC Information System --> Working With WinCC --> Archiving Process Values --> Output of Process Values -->Process Value Output in Process Pictures --> Process Value Output in the Form of Trends in Process Pictures --> Operation in Runtime --> How to Determine the Coordinates of a Point"):
The displayed values can be assigned an additional attribute in the form of a letter:
Letter "i." : The displayed value is an interpolated value.
Letter "u." : The displayed value has an uncertain status. The value is not certain if the initial value is not known after runtime has been activated, or when a substitute value is used.

I have a Simulink Model with with multiple GotoFrom Tags. Instead of their individual name i want to display their current value. In the following picture i would want to substitute A with its respective value.
When I entered a value in the input box and submitted it, the mandatory item verification failed, and the system displayed a message indicating that a parameter was empty and instructed me to enter a value. The code for obtaining the input value is as follows:
(see the solution in column C)
can you give me some advice about it?
The possible cause is that the method for obtaining the value is incorrect. As a result, the value in the input box cannot be obtained.
Use the onchange event to assign a value to the model and obtain the value of the input box. The method is as follows:
Initialize the model.
data:{
accountValue:''
}
Bind an event to the input box.
<input #change="getAccountValue" value="{{accountValue}}"></input>
Assign a value.
getAccountValue: function(e) {
this.accountValue = e.value // Here, e.value instead of e.target.attr.value is used.
}
Refer to the official document instead of generating a JavaScript object for coding. A JavaScript object may lead to compatibility issues.
Currently, the data binding mode of the quick app is unidirectional.
The value entered in the input box does not change the value of accountValue in data.
If the value of the input box is changed by setting this.accountValue to xxx, the onchange event of the input will not be triggered.
In this.accountValue = xxx format, if the value of accountValue before and after the change is the same, the page will not be re-rendered.
Creating a form with no values and would like the input field to default to empty for two reasons:
Want users to be able to see the placeholder text.
Having a default number means the users can ignore the field by default. (I know I can validate the field, but that is just a bad user experience.)
The problem:
el-input-number fields default to a number (0 or whatever the :min value is set to).
This covers up the placeholder text.
The users can click save with the default number still in place. (I will validate, but don't want users to have to submit a bad value to know what to do.)
Does anyone know how to make the input field have the default value be just empty?
just give it a default value of undefined

I have two parameters in report:
week ---> has isForPrompting="true" property
year ---> has isForPrompting="true" property
But when I add a single value input control and run the same report on JasperReports Server, only a pop up window is opening up and not the the single value input control.
Also If I add a single value input control to my other reports, its showing up when I run the reports on JR Server.
I really don't understand why the single value input control is not showing up for the current report when everything is running well on iReport designer?
Most common problem: Your input control doesn't match exactly. The input control ID has to match the parameter. Remember that it's case sensitive.
if you create a new dataset, mandatory fields which are not set yet are marked with a wiggly red line.
it seems, that only string-values ( or several fields, but at least no integers ) are marked this way.
if integer-references are used ( 1-based ), the regarding fields are filled with 0 per default which causes the red line to disappear.
is there any way to leave those fields empty per default?
thanks for hints!
For integer and real fields you could set the ShowZero property to No (on the control or extended data type). Then zero values will appear with a red wave line.
For new base enums leave a blank zero enum value (by convention name it None).
Dynamics Ax does not have an "null" concept for fields. It uses some "zero" values for all data types - so you need to use some other NoYes field to express what you want if 0 is not empty
