ScriptEvaluationError when previewing simple report with one image (URI source) [message #194761] Wed, 11 October 2006 12:40 Go to next message

Hi,

[BIRT v2.1.1 - I just did a fresh update this morning.]

I just created a very simple report - a blank report, with one image added
to it. In the URI for the image (within the 'Edit Image Item' window) I
specified:

http://www.eclipse.org/eclipse.org-common/themes/Phoenix/ima ges/header_logo.gif

Clicking the preview button in that same window successfully displayed the
image.

When I go to the report preview tab, I see the image, as well as the
date/time from the master, however I also get a ScriptEvaluationError:

- There are errors evaluating script
" http://www.eclipse.org/eclipse.org-common/themes/Phoenix/ima ges/header_logo.gif".
Error.ScriptEvaluationError ( 1 time(s) )
detail : org.eclipse.birt.report.engine.api.EngineException: There are

....

If I understand this right, does this mean the URI is getting evaluated as
Javascript, in which case I would need to enclose the image URI in quotes so
that it would be evaluated as expressions? This is the only way I could get
it to work without throwing an error. However, then the preview button in
the 'Edit Image Item' window does not work, displaying a dialog box with a
file not found error.

The URI field in the 'Edit Image Item' window does not seem to suggest this
requirement, as confirmed by the fact that the preview button in that window
succesfully retrieves the image.

Thanks,

Jason

Hi Jason,

I don't understand the requirement for the double-quotes, but I have
noticed this behaviour as well, and wanted to point out that it is
documented as a requirement.

If you look at the Field Guide to BIRT >> Laying Out a Report >> How to
insert a linked image, it states:

To link to an image stored in any other location:
In Select picture from, select URI.
Under Enter URI, specify the location of the image file. Enclose the URI
in double quotation marks (" ").
The following expression is an example of a URL for a file in a remote
location:
"http://mysite.com/images/companylogo.jpg"

The one thing you mentioned below I did not experience however. When I
have the quotes surrounding the URI and do a preview in the Edit Image
Item window I can see the image.

I would be interested in knowing why the double quotes are a requirement
as well.

I'm using BIRT 2.1.1.v20060926-0959

Thanks for the heads-up. I guess I need to be a little more thorough in my
documentation reading. That said, it would be nice if the dialog performed
some validation as well.

The difference here is that I surrounded my URI with single quotes, rather
than double. I just tried with double quotes, and experienced the same
successful behavior as you.

Design Engine API Example - ImageHandle.setURL and quotes (Was: ScriptEvaluationError when previewin [message #194785 is a reply to message #194777] Wed, 11 October 2006 15:19 Go to previous messageGo to next message

Following on from this discussion - I have been working with a similar
scenarion using the Design Engine API. The example provided at
http://www.eclipse.org/birt/phoenix/deploy/designEngineAPI.p hp has the
following code:

....
ImageHandle image = factory.newImage( null );
CellHandle cell = (CellHandle) row.getCells( ).get( 0 );
cell.getContent( ).add( image );
image.setURI(" http://www.eclipse.org/birt/phoenix/tutorial/multichip-4.jpg");
....

This generates an rptdesign file
(http://www.eclipse.org/birt/phoenix/deploy/sample.rptdesign) containing an
unquoted expression value for the image location, resulting in the same
ScriptEvaluationError mentioned in my previous thread.

In the current version of the Design Engine API, is the solution to call
image.setURL (as setURI has been deprecated) with escaped double quotes?
The JavaDoc for this class just states 'the uri to be set' for the uri
parameter.

image.setURL("\" http://www.eclipse.org/birt/phoenix/tutorial/multichip-4.jpg \"");

Thanks,

Jason

Ah, I missed that, thanks for pointing that out.
