Creating a component need help retrieving a string value

joefrancois — Sat, 16 Nov 2024 08:15:37 GMT

Hello,

I am in the process to create a new component. I am able to retrieve all parameters as strings except for a Parameter closed list, which gets pickup as a variable and not a string.

The METHOD parameters is the only CLOSED_LIST parameter. Please see XML below.

I used a standard ElementParameterParser.getValue to retrieve the set value.

Here I set my string Variable with the value I just retrieved.

As you see, when I try to run it, I get a message that the system cannot resolve the POST variable, but it is not a variable but a value of the httpMethod_<%=cid%> value.

When I look at the code, I can see all my other variable were set properly but for myhttpMethod_<%=cid%> variable value. The POST was set without the quotation mark. When I hard code the POST value, than the component works as expected.

Any help to resolve this would be very much appreciated.

Regards,

Joseph

Not sure (not much experience creating components), but while generating the code, it resolves to a var name in stead of a string value, "\"POST\"" escape your quotes.

Why not use default and set it to POST

I realized that I had to append the quotes as I was reading in the variable. Here is the line I changed that got me the result I was looking for.

String method = "\""+ElementParameterParser.getValue(node,"__METHOD__")+"\"";

Thank you for your support.
