Can we increase the size of the parameters input field on a step with a "call activity"

We are migrating from Pega 6.3 SP1 to Pega 7.3.1.

Some users indicated that the parameter field on a step making a "call" is smaller in Pega 7.3 than it is in Pega 6.3. It may be because of font size but still perception is, it is smaller.

Is there an easy way to change a "section" or "harness" to increase the size that seems to be fixed to 20 in the generated HTML ? I would like to have at least 50 for the size of the input field.

Thank you and have a nice day !

the link simply says that it cannot be changed because the rule is final.

The enhancement for the product team should be to put the "section / harness" available. Please. :-)

In the mean time we might write a "Chrome extension" to increase the size when required.

It should be pretty simple to do since the value is harcoded to 20.

Hi Lochana,

The more descriptive I can be is this:

When we edit a step with a "call" method and we expand the method to see the parameters, we would like the input field of the parameter to be larger than the fixed size of 20 that is currently set.

Preferably, we would like it to be something like "70%" of the width of the space available on that line.

It that enough descriptive? Please let me know. Thank you.

I found a way to increase the size of the parameter field! 

You need to do a private edit on the pzParamInput section. remember that when you search for this you need to put "old:" in front of pzParamInput in the search box. It is a "final" rule found under "Pega-Desktop".

So, in this rules, you have a HTML source that contains the following series of lines:

String paramName = UIPage.getString("pyParametersParamName"),

paramDesc = UIPage.getString("pyParametersParamDesc"),

paramType = UIPage.getString("pyParametersParamType"),

paramReqStr = UIPage.getString("pyParametersParamReq"),

paramInOutStr = UIPage.getString("pyParametersParamInOut"),

paramSize = "100%",

paramSPStr = UIPage.getString("pyParametersParamSmartPrompt"),

paramSPRule = UIPage.getString("pyParametersParamSmartPromptRule"),

paramSPRClass = UIPage.getString("pyParametersParamIntelliRule"),

paramSPBClass = UIPage.getString("pyParametersParamIntelliBaseClass"),

paramSPDataNode = UIPage.getString("pyParametersParamSmartPromptDataNode"),

paramDropDown = UIPage.getString("pyParametersParamDropdownValues"),

paramDefVal = UIPage.getString("pyParametersParamDefaultValue");


As you can see, I changed the paramSize for "100%" and problem is solved !


I haven't figured out yet, where the value is obtained in the previous line of the HTML source. As soon as I find out, I'll be posting something about my discovery.


I know I wasn't the only person wanting the parameter field to be wider. Spread the news ! :-)
