How can I set variable as empty string in logic apps?
If I set no value in Value field I get "Error: Failed to save logic app. Definition contains invalid parameters."
If I set quotationmarks in Value field, I get a pair of escaped quotationmarks in output:
One workaround is to set it to trim(' ')
Set it to another var initialised which was set as null (no value)
If you want to set the empty value you need go to the Code view and set the value to " "(double quotation marks with a blank space) like below picture.

I have an array variable "Names" with this values for example ["Unity","Block","PRD","Monit"] and want to get each of them value into a new variable.
The output desired would be something like:
Variable Group = Unity
Variabel Test = Block
(...)
As this is an array i thought a basic Names[0] would give me the first value and so on for 1,2,3,etc, but on a logic app I can't figure out how that works.
Is this possible?
Thanks
You do know select value from an array have to specific the index, just don't know how to use variable expression.
Use variables('variable_name') get the variable value and then add the parameter [index] behind it to select the value you want. Just like the below picture shows.
I have a report which uses an expression to provide data for each particular page. I have been able to get the report to display the correct data, however the column that the expression is in, is not necessary and the rest of the table will not fit on the page. I need to get rid of the column but reference the expression somewhere else on the report. I have tried a few things, such as referencing the text box but get Scope errors.
I would like the expression to display where the green line is, and make the first column invisible.
Any ideas how I can reference the value of this textbox in the desired location?
Current state of report:
expression ="Load Number: " & Fields!TPLD_SYS_NO.Value & " | " & "Vehicle:" & Fields!TPLD_TPVH_REG.Value & " | " & Fields!TPLD_REF.Value
expression used to reference 1st expression =ReportItems!TPLD_SYS_NO1.Value
error The value expression for the textbox 'textbox8' refers to the report item 'TPLD_SYS_NO1'. Report item expressions can only refer to other report items in the same grouping scope or a containing grouping scope
This is from memory, zero testing I'm afraid so it might not be quite right but it should be close enough to follow.
A couple of options.
If the report will only ever show one value for this expression then you should be able to just use your original value expression directly in the 'new' text box but where you have Fields!myField.value, replace these with FIRST(Fields!myField.Value, "myDataset") where myDataset refers to the name of your dataset (you must include the quotes).
If the report is grouped so this expression will evaluate to two or more different values then you need to add a row inside the lowest group that will have all the required fields in either itself or child groups. As I guess I would say that would be the same level as your Total textbox. So Insert Row / Inside Group Above and then use the expression above but without the dataset name. You should be able to not specify this or if you get problems, specify it as the name of the rowgroup that your new textbox sits in.
To get an out of scope value, you can create custom code functions to store the value and assign the text as follows :
="Load Details" + Code.Save_TPLD_SYS_NO(Fields!TPLD_SYS_NO.Value)
When you need to recall the value at some other point you can reference a function that returns the saved value like:
=Code.GetSaved_TPLD_SYS_NO(true)
In your custom code you can create a variable that will hold the value and that the function would be something like:
NOTE : This is untested and the code comes from memory, you may have to fiddle a bit to get the correct syntax.
Public Dim Shared TPLD_SYS_NO As String ="";
function Save_TPLD_SYS_NO(value As String) As String
Begin
TPLD_SYS_NO = value
Return ""
End Function
function DisplayAndSave_TPLD_SYS_NO(value As String) As String
Begin
TPLD_SYS_NO = value
Return value
End Function
function GetSaved_TPLD_SYS_NO(resetValue as Boolean) As String
Begin
Dim result As String = TPLD_SYS_NO
If resetValue=true Then
TPLD_SYS_NO = ""
End If
Return result
End Function
I am retrieving some data using stored procedure and calling it within the database connector in mule. I have to include a condition when I pass a value which is not there in the database it should capture the error. For this I am using a choice component where I have to check whether the payload is null. But when running the flow in debug mode I found that the payload holds the value
{resultSet1=[]}. I tried #[message.payload.isEmpty()], #[message.payload!=null] and #[payload.resultSet1 != null]. But they weren't working. Could anyone help to resolve this. Thanks in advance.
You can use empty to check for:
Testing for Emptiness: The special literal empty tests the emptiness of a value. It returns an empty value depending on context. empty evaluates to:
null
boolean false
empty strings or strings containing only white space
zero
empty collections
The expression #[foo == empty] evaluates to true if the value if foo satisfies any of the requirements for emptiness.
Which in your case would be
#[payload.resultSet1 != empty]
The best way is #[payload != null && payload.size()>0]
you can try comparing with 'null" or "0" or, simply, "empty" and it should work fine for you :)
#[payload == empty]
should work.
Is there any way to query Datastore for entities where a specific property should not be the empty string?
I'm not referring to missing properties. I really mean non empty strings.
By using filters you can specify that value of the property is greater than "" (empty string). I don't use Go so I can't guarantee if it'll work but in other languages this trick usually works...
q := datastore.NewQuery("Example").Filter("Property >", "")
I have a mask setup on a date field using the angular-ui masks module like so:
<input type="text"
id="date"
ng-model="transaction.date"
ui-mask="99/99/9999" />
If I have 30/05/2013 in the field and want to change that to 10/05/2013 by simply putting a '1' at the start it pushes all the characters over so it becomes 13/00/5201.
Is there way to force ui-mask to overwrite the character insted of inserting it? (This would save someone from hitting 'delete' then the character.
Example: http://jsfiddle.net/5NbD7/
If you type '30' at the front of my example you will end up with 30/01/0120 I would rather it override the characters and produce 30/01/2010
I don't know it there is an easier way, but you try the following :
You will need to download mask.js, unminified, from source and link it in your html, if you haven't already done so.
https://rawgithub.com/angular-ui/ui-utils/master/modules/mask/mask.js
Then you will need to modify the source code of mask.js like this (seach for the comment //Update Values and put this code below) :
...
// Update values
if (oldValueUnmasked !== "" && oldValueUnmasked!==valUnmasked && !isDeletion) {
var charIndex = maskCaretMap.indexOf(caretPos);
if (charIndex === -1) {
charIndex = maskCaretMap.indexOf(caretPos+1);
}
valUnmasked=valUnmasked.substr(0,charIndex).concat(oldValueUnmasked.substr(charIndex,valUnmasked.length));
}
...
Now, before updating the value, mask will do a concatenation of the characters in the old value and those in the new value, depending on the position of the cursor (caret).
It's by no means an ironproof solution, but it should give you an idea of where to look if you want to customise the input more or check that this change does not break anything else.

I think that the way typed characters are inserted or overwrite input text depends on the keyboard current insert mode. Users can simply change the default pressing the Ins key.
The only way to change it from code would be forcing an Ins key press but this isn't allowed in Javascript.
