Hi,
I have this bit of flow script:
function myFunction() {
var form = new Form(formDef);
form.createBinding(formBind);
var success = false;
var errMsg = "";
var count = 0; // to prevent endless loops
while(!success && count < 10) {
try {
form.load(myForm);
var viewData = { some: data, errMsg: errMsg };
form.showForm(formDisplayPipeline, viewData);
form.save(myForm);
success = myHelper.storeNewForm(myForm);
}
catch(error) {
errMsg = "other error: " + error;
print(errMsg);
success = false;
}
count++;
}
cocoon.sendPage("displayResult");
}
FormDisplayPipeline points to a pipeline:
<map:generate type="jx" src="myTemplate.jx"/>
<map:transform type="cinclude"/>
<map:transform type="forms"/>
<map:transform src="stylesheets/resources/forms-samples-styling.xsl">
<map:parameter name="uri" value="stylesheets/resources"/>
</map:transform>
<map:call resource="html-layout"/>
<map:serialize type="html"/>
The above works ok. However, when something happens errMsg is set and the
loop starts from the top, but rather than redisplaying the form, I get an
error message stating 'Generator already set'. This repeats until count==10.
What should I do to redisplay the form properly with error message?
Thanks.
Bye,
Helma van der Linden
