[ 2.6.2 ]Function in javascript file not recognized

egau

Hello, 
 
I've created a file "functions.js" that I put in a "JS" folder in my workspace resource folder. I added this file in the Resources part of a rptlibrary ("JS/functions.js"). 
 
I use a function defined in the JS on a library object. Finaly I add the objet to a rptdesign, the js file is automatically added in the Resources part ("JS/functions.js") of the rptdesign but when I generate the rptdesign, I have an error message telling me that 
 
"ReferenceError: "formatStuff" is not defined at line 8 of chart script:'' 
 
Function : 
<pre class='_prettyXprint _lang-auto _linenums:0'>function formatStorage( value )</pre>
 
Used in a chart object : 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>value = formatStuff(value);</pre>
 
Do I have to import the js somewhere else ? Include something so that it works ? 
 
Thanks in advance. 
 
Edit : I checked, and I have 
 
<pre class='_prettyXprint _lang-auto _linenums:0'><list-property name="includeScripts">
<property>JS/functions.js</property>
</list-property></pre>
 
In the rptdesign XML so I really don't understand why my functions are not recognized -_-

hi, 
 
the chart and crosstab scripts are the only ones using a different scope as the rest of all the scripts, so you can't easily access a function that is defined in the other scope. 
 
A possible workaround is to create a persistent global variable: 
Put in initialize for every function: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
reportContext.setPersistentGlobalVariable("myFunc", formatStuff());
</pre>
 
In chart use 
<pre class='_prettyXprint _lang-auto _linenums:0'>
function beforeDrawAxisTitle( axis, label, icsc ){

func = icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("myFunc");
func(something);
}
</pre>
 
I m not sure but i think that it would be sufficient to use a global variable instead of a persistent global one.

Hello, 
 
Thanks for the answer, I tried your method but I got some issues : 
 
As you proposed, I put the in the initialize method of my rptdesign this line : 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>reportContext.setPersistentGlobalVariable("stringFormatStorage", stringFormatStorage());</pre>
 
 
Then in the chart object, I put : 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>func = icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("stringFormatStorage");
func(value)</pre>
 
 
And I got these 2 errors : 
 
'org.eclipse.birt.report.engine.script.internal.ReportContextImpl.setPersistentGlobalVariable(string,org.mozilla.javascript.Undefined)' cannot be found (/report/method[@name="initialize"]#1) 
 
and this one ( I guess it's related to the 1st one ) : 
 
TypeError: func is not a function, it's an object at line 9 of chart script:'' 
 
Do you have an idea ?

Well thanks for your help, it also gave me new keywords for google so I finally found this topic : 
 
<a class='bbc_url' href='http://www.birt-exchange.org/org/forum/index.php/topic/20615-report-resource-scripts-in-chart/page__s__b5fb14be2446aff9de6f515a187737d9'>http://www.birt-exchange.org/org/forum/index.php/topic/20615-report-resource-scripts-in-chart/page__s__b5fb14be2446aff9de6f515a187737d9</a> 
 
 
You mentionned the reason and the solution is , in the chart script ( no need to script anything in the initialize of the report) : 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>var myParameter = 10;
icsc.getExternalContext().getScriptable().setGlobalVariable("myValueParameter", myParameter );
var value = icsc.getExternalContext().getScriptable().evaluate("stringFormatStorage(myGlobalParameter);");</pre>
