Update sessionScope variable from combobox

Category: Custom JSF code (Eclipse IDE)
Platform: All
Release: 8.5.3
Role: Developer,Administrator
Tags: sessionScope,Hide When
Replies: 2

So, I want to hide a field and only show it when a particular value is selected from a comboBox.

Here is what I have:

afterPageLoad: create and set the variable to false
1. sessionScope.put("showSC", false);

For the field that is to show or hide, set the visibility to the sessionScope variable:
2. sessionScope.get("showSC");
This part works, the field is hidden. I can change the variable to true in line 1 above and it does show.

When a value ("Operations") is selected in the comboBox, use javascript to set the sessionScope variable:
3. onchange of comboBox
var cat1 = document1.getItemValue("Category1");
if(cat1 == "Operations")
{
sessionScope.put("showSC", true);
}
else
{
sessionScope.put("showSC", false);
}

The javascript above never evaluated to True. I can verify the document1.getItemValue("Category1") is pulling the value by setting that as the default value in a field.

I'm not sure what I am doing worng.

Any thoughts?

A few things to check

First, are you doing at least a partial refresh of the control that should be hidden or shown when the onchange event happens? That is needed. Next, add a print statement to see what value you are getting from your getItemValue. You might be better off using getComponent("comboboxlabel").getValue() instead since that is not dependent on when the value gets written to the Domino data source. Howard

Re: Update sessionScope variable from combobox

Got it!

I was already doing a Full Update on change, planning on changing it to a panel/partial update later.

I have not used the getComponent method before. I tried it in line one of the onchange of the comboBox like so:

var cat1 = getComponent("comboBox1").getValue()

if(cat1 == "Operations")

{

sessionScope.put("showSC", true);

}

else

{

sessionScope.put("showSC", false);

}

That fixed it.

Thanks Howard!
