Hello,<br />
<br />
I have really basic-problems with the „Example plugin for Expression Builder” posted on <a class='bbc_url' href='
http://www.birt-exchange.org/devshare/designing-birt-reports/1101-example-plugin-for-expression-builder/#description'>Example plugin for Expression Builder - Designs & Code - BIRT Exchange</a> and <a class='bbc_url' href='
http://birtworld.blogspot.com/2008/09/birt-231-adding-functions-to-expression.html'>BIRT World: BIRT 2.3.1 - Adding Functions to the Expression Builder</a>. <br />
<br />
Unfortunately I don’t even can start the attached example correct. I’m not very confirm with eclipse and the import and export of eclipse-projects.<br />
<br />
With the following steps I tried to import and export the project to insert the TestFunction() into BIRT:<br />
<br />
1.) I create a new plugin-project in eclipse and name it “plugin_test_02”. I do not change any other setting in the project-wizzard.<br />
<br />
2.) I import the downloaded archive-file in my project. I just choosed the “my.expression.functions”-directory in the extracted archive. I choosed the complete content of the directory for the import. I use the “overwrite existing resources without warning”-option and overwrite the existing files. <br />
<br />
3.) I export the project as “Deployable plug-ins and fragments”. As destination-directory I choosed the eclipse-plugins-directory. <br />
<br />
4.) I get the message: “Errors occurred during the export operation…”. The generated log-file has the following content:<br />

^^^^^^^<br />
The method execute(Object[], IScriptFunctionContext) in the type IScriptFunctionExecutor is not applicable for the arguments (Object[])<br />
<br />
4 problems (3 errors, 1 warning)<br />
<br />
So how can I get the example running? I want to try to insert some custom functions into birt.<br />
<br />
Thanks for some answers!<br />
