Flex 3: Passing Array to Custom Component

Question

I created a custom button component that accepts an array as a property. I set the property as follows:

titleDims="[{Month: comboBox1.text, Year:comboBox2.text, Sales Order:comboBox3.text}]"

and I get the following error:

"1084: Syntax error: expecting rightparen before colon."

Wat is wrong with the array syntax?

I thought you had to do that when passing a parameter to an custom component — Ivan

Is the custom component expecting a string or an array? isn't this json notation? — Amarghosh

I could be wrong, but I think Ivan wants to set a property in MXML, so quotes are required. Ivan, in the future, please specify if you're talking about ActionScript or MXML because it's not always easy to tell from context. — Josh Tynjala

Yes. Good point. I was trying to do this in MXML not Actionscript. — Ivan

Your problem is your formatting. Let's break it down:

titleDims = [{
    Month: comboBox1.text,
    Year:comboBox2.text,
    Sales Order:comboBox3.text // Whoops! There's a space here!
}]

I suggest to change it to SalesOrder instead.

If you really need spaces in the key, you can do this:

titleDims = [{
    'Month': comboBox1.text,
    'Year': comboBox2.text,
    'Sales Order': comboBox3.text
}]

+1 But interestingly, you can inject spaces in to variables names. Try this code: var o:Object = {}; o["sales order"] = "something"; trace(o["sales order"]); Now, as to why someone would do that, I don't know :)

I tried that and I get the same error. However, I will need spaces in the keys. I even tried: titleDims="[{Month: comboBox1.text}]" and the same error is generated!

@OP Why the quotes? That makes it a string. Isn't titleDims=[{Month:comboBox1.text}] what you want?

just out of curiosity - I will need spaces in the keys - what kind of requirement is that?

cb1 = comboBox1; cb2 = comboBox2; cb3 = comboBox3;

Option A

titleDims="[{'Month': cb1.text, 'Year':cb2.text, 'Sales Order':cb3.text}]";

Option B

titleDims="[{Month: cb1.text, Year:cb2.text, SalesOrder:cb3.text}]";

Option C

titleDims="[{Month: cb1.text, Year:cb2.text, Sales_Order:cb3.text}]";

I'm ignoring your use of setting titleDims to a string first and assuming you have some code that needs it that way. In the future, you don't need to quote this declaration.
