FormAPI

summergs

Hello,

Can someone provide me with an example of how to invoke an external perl script from FormAPI?

Many Thanks!

You can't (directly) invoke a perl script from FormAPI. FormAPI runs on the client machine, while perl is installed on the server machine.

What you can do is to use the callServer method to point ot a URL which is serviced by your perl script. Something like this:

var myData = new Object();
myData.param1 = "value1";
myData.param2 = "value2";
...
IWDataCapture.callServer("/URL/to/your/perl/script", myData, false);

Do you know if there is a way to force a refresh of an inline command in a DCT?

I am having a problem with the inline command only working when creating a new DCR. During an edit of the DCR, the inline command is not invoked.

Any Ideas?

Dwayne

I suspect that you are misinterpreting the symptoms. It seems unlikely to me that the inline would run only on a new DCR, and not on an existing DCR. To the best of my knowledge, the inline is parsed without any knowledge of what DCR, if any, will be loaded into it.

In other words, how do you know that the inline is not running? Those symptoms might help with a diagnosis.

Howdy,
Its easy. I have an inline command that gets the Branch Name. Lets say "Federal001" is my branch name.
I create a new DCR in this branch, thus the value entered into the field is "Federal001".
I copy this DCR to another branch "State001".
When I edit the DCR, the branch name in the field is remains set to "Federal001".
I do a IWDatacapture.redraw, nothing changes.
I put a print statement in my ipl that is called in the inline, and it clearly indicates that the ipl is not being called.
I create a new DCR in branch "State001", the inline is called and I get a print.
I edit the DCR in branch "State001", the inline is NOT called as I do NOT get a print.

Wacked huh

Note any value in the DCR is applied to the DCR after the inline is called. So if you have a DCR that has an inline but already has a value in that field it will be "overwritten" although this does not explain why you are not seeing the inline fire on edit.

Correct. If I go into the xml file and delete the stored value, then edit the DCT, I get a message in my field " (No value was entered.)"

brandon1

Are you viewing the DCR not editing it? Because in that case an inline does not fire. When you said (No Value was Entered) it sounded like that was the case.

No. I am editing the DCR. (TS5.5 Windows2000, IE6)

Dwayne

The sequence of events that happens when you edit a DCR:

this sets default values as specified in the DCT
the DCR is loaded into memory, overwriting all default values with the contents of the DCR

If you want "proof" that the inline is being run, then make a syntax error in it, and try to edit a DCR. It won't work. For further proof that this is not an inline issue, take the output of your inline command, and paste it directly into the DCT (without the <substitution> lines, of course). You'll see the same behavior.

That is a good idea. I therefore edited the inline command changing the ipl filename so some erroneous name.
I then tried to edit the DCR.
I got an error:
An exception was thrown: Can't open perl script "D:\iw-home\local\bin\zzzzzzzbranchName.ipl": No such file or directory

So it does appear that the file is being located. Why would it not run the file????
(Keeping in mind that it works great when creating a new DCR)

Adam Stoller

Is your inline being used within - or inserting a 'default' value?

If so - I believe it will only work when the DCR is being created the first time and that would explain the behavior you're seeing - it certainly won't change anything if there is already a value associated with that field.

The DCT:

<item name="ProjectNumber">
<description>Extracted from Branch Name</description>
<text size="20" maxlength="20">
<inline command="D:\iw-home\iw-perl\bin\iwperl.exe

\iw-home\local\bin\my.ipl" />
</text>
</item>

The IPL:

$ENV{NLS_LANG} = 'AMERICAN_AMERICA.UTF8';
$ENV{TEMP} = 'C:\TEMP';
$ENV{SYSTEMROOT} = 'C:\WINNTADV';
my $areavpath = $ENV{IW_WORKAREA} || "";
$output = "<?xml version='1.0' encoding='UTF-8'?>\n";
$output .= "<substitution>\n";
my $brchvalue = ($areavpath =~ m/\/default\/main\/government\/internet\/Projects\/(.*?)\/WORKAREA\/.*$/);
$output .= " <default>$1</default>\n";
$output .= "</substitution>\n";print $output;exit();

summergs

So yes. You are correct. How can I pass the value in all the time?

$output .= " <default>$1</default>\n";

Adam Stoller

$output .= " <default>$1</default>\n";

Exactly - that sets a DEFAULT value - it will not replace a value that already exists.

I think the only way to do that would be with FormAPI code - sorry - don't have time to provide detailed code right now - but I think you can probably find some examples if you look hard enough through the forums

Anyone have any ideas?

jbonifaci

var branchName = new String(unescape(this.location));
branchName = branchName.replace(/^.*\/([^\/]+)\/WORKAREA\/.*$/, "$1");
IWDatacapture.getItem("/ProjectNumber").setValue(branchName);

summergs

Awesome! Works great! Many Thanks!
